What is RANDOM ORACLE? What does RANDOM ORACLE mean? RANDOM ORACLE meaning & explanation
What is RANDOM ORACLE? What does RANDOM ORACLE mean? RANDOM ORACLE meaning - RANDOM ORACLE definition - RANDOM ORACLE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a random oracle is an oracle (a theoretical black box) that responds to every unique query with a (truly) random response chosen uniformly from its output domain. If a query is repeated it responds the same way every time that query is submitted. Stated differently, a random oracle is a mathematical function chosen uniformly at random, that is, a function mapping each possible query to a (fixed) random response from its output domain. Random oracles as a mathematical abstraction were firstly used in rigorous cryptographic proofs in the 1993 publication by Mihir Bellare and Phillip Rogaway (1993). They are typically used when the cryptographic hash functions in the method cannot be proven to possess the mathematical properties required by the proof. A system that is proven secure when every hash function is replaced by a random oracle is described as being secure in the random oracle model, as opposed to secure in the standard model of cryptography. Random oracles are typically used as an ideal replacement for cryptographic hash functions in schemes where strong randomness assumptions are needed of the hash function's output. Such a proof generally shows that a system or a protocol is secure by showing that an attacker must require impossible behavior from the oracle, or solve some mathematical problem believed hard in order to break it. Not all uses of cryptographic hash functions require random oracles: schemes that require only one or more properties having a definition in the standard model (such as collision resistance, preimage resistance, second preimage resistance, etc.) can often be proven secure in the standard model (e.g., the Cramer–Shoup cryptosystem). Random oracles have long been considered in computational complexity theory, and many schemes have been proven secure in the random oracle model, for example Optimal Asymmetric Encryption Padding, RSA-FDH and Probabilistic Signature Scheme. In 1986, Amos Fiat and Adi Shamir showed a major application of random oracles – the removal of interaction from protocols for the creation of signatures. In 1989, Russell Impagliazzo and Steven Rudich showed the limitation of random oracles – namely that their existence alone is not sufficient for secret-key exchange. In 1993, Mihir Bellare and Phillip Rogaway were the first to advocate their use in cryptographic constructions. In their definition, the random oracle produces a bit-string of infinite length which can be truncated to the length desired. According to the Church–Turing thesis, no function computable by a finite algorithm can implement a true random oracle (which by definition requires an infinite description). In fact, certain artificial signature and encryption schemes are known which are proven secure in the random oracle model, but which are trivially insecure when any real function is substituted for the random oracle. Nonetheless, for any more natural protocol a proof of security in the random oracle model gives very strong evidence of the practical security of the protocol. In general, if a protocol is proven secure, attacks to that protocol must either be outside what was proven, or break one of the assumptions in the proof; for instance if the proof relies on the hardness of integer factorization, to break this assumption one must discover a fast integer factorization algorithm. Instead, to break the random oracle assumption, one must discover some unknown and undesirable property of the actual hash function; for good hash functions where such properties are believed unlikely, the considered protocol can be considered secure.

Confidential computing with SQL secure enclaves  - BRK3157
Imagine a database system that can perform computations on sensitive data without ever having access to the data in plaintext. With such confidential computing capabilities, you could protect your sensitive data in use from powerful adversaries, including malicious machine admins, cloud admins, or rogue DBAs, without scarifying database system’s query processing power. With the Always Encrypted and secure enclave technologies, such as Intel Secure Guard Extensions (SGX) and Virtualization Based Security (VBS) in Windows, this powerful vision has become a reality. Join us for this session to learn about these game changing technologies that are now available in SQL.

CryptDB: Processing Queries on an Encrypted Database
Online applications are vulnerable to theft of sensitive information because adversaries can exploit software bugs to gain access to private data, and because curious or malicious administrators may capture and leak data. CryptDB is a system that provides practical confidentiality in the face of these attacks for applications backed by SQL databases. CryptDB's approach is to execute SQL queries over encrypted data. It can do so practically with two techniques: using a collection of efficient SQL-aware encryption schemes, two of which are new, and onions of encryptions which allow dynamic adjustment of encryption schemes. An analysis of a trace of 126 million SQL queries from a production MySQL server shows that CryptDB can support operations over encrypted data for 99.5% of the 128,840 columns seen in the trace. Our evaluation shows that CryptDB has low overhead, reducing throughput by only 26% for queries from the standard SQL benchmark TPC-C when compared to unmodified MySQL.

Analyzing Blockchain and Bitcoin Transaction Data as Graph
Blockchain technology and Bitcoin will potentially revolutionize business transactions. Blockchain offers a robust, decentralized platform for privacy and trust. It underlies the digital crypto-currency Bitcoin, which can be exchanged freely and anonymously, without a central authority. Bitcoin transactions - recorded publicly, provide an invaluable dataset to gain insight into the behavior of digital currency and the underlying Blockchain technology. Blocks, transactions with potential multiple inputs and outputs, and flow of bitcoins between addresses, form a sophisticated real-time graph. This talk details a pipeline used to gather bitcoin transaction data and analyze it with powerful graph cloud database technologies.

PostgreSQL Security. How Do We Think? - Masanori Oyama - FOSSASIA Summit 2017
Speaker(s): Masanori Oyama (Tokyo) Abstract: In recent years, applicable area of PostgreSQL has quickly extended into the enterprise sector thanks to continuing effort of the community to improve performance and functionality. As a result, there is an emerging demand to use PostgreSQL in more security-critical circumstances.In this presentation, I will talk about the following two topics. * Considerations for securing a database system. * Current status of database audit on PostgreSQLI am working for the open source software center (OSS center) of NTT which is the largest telecommunications company group in Japan. We have encouraged many of our customers to migrate a lot of database systems to PostgreSQL so far and this contributed much to cost reduction.Some projects need to conform to security standards, for example PCI DSS (Payment Card Industry Data Security Standard). It is one of the most prevailing security standard in the world. However it is not easy to build and operate a PostgreSQL-based system conformant to these security standards. I'd like to describe some aspects required for secure database systems in general, such as encryption, key management, identity management and auditing.Then I explain considerable points for building a secure database system using PostgreSQL, and show the remaining challenges for secure database systems using PostgreSQL.Finally, I introduce a forked version of pgaudit that we are maintaining, then explain how to use it. pgaudit is developed by 2ndquadrant and Crunchy Data, especially by David Steel with a great contribution. However, it does not meet our customer's requirements. For example, It cannot output the audit log and server log separately, it cannot audit Superuser fully, etc. So we forked it and added some changes.

System Design - Sharding | Data Partitioning
Sharding or Data Partitioning: - Sharding is a technique to break up a big database into many smaller parts - Horizontal scaling means adding more machines, which is cheaper & more feasible - Vertical scaling means improving servers - Partitioning Methods: - Horizontal partitioning: - In this we put different rows into different table(db), i.e. rows can be based on location with zip codes, this is also range based sharding - Problem is if range is not choosen carefully, it'll lead to unbalanced servers. - Vertical Partitioning: - In this we divide data to store tables related to a specfic feature to their own servers.i.e. In Instagram, we can have 1 for user profile, 1 for photos, 1 for friend list. - Problem is in case of additional growth, its necessary to further partition a feature specific DB across servers. - Directory based Partitioning: - In this, create a lookup service which knows your current partitioning scheme & get it from DB access code. - To find out a data entry, we query directory server that holds the mapping between each tuple key to its DB server. - This is good to perform tasks like adding servers to the DB pool or change our partitioning scheme without impacting application. - Partitioning Criteria: - Hash-based partitioning: - In this we apply a hash function to some key attribute of the entity we're storing, that gives partition number. - Make sure to ensure uniform allocation of data among servers - Problem is it effectively fixes total number of DB servers, since adding a new server means changing the hash function, which would require redistribution of data & downtime, the workaround is Consistent Hashing. - List Partitioning: - In this each partition (DB server) is assigned a list of values, i.e. APAC, EMEA, US region has respective partition. - Round-robin Partitioning: - One by one assign which ensure uniform data distribution - Composite partitioning: - Combining any of above partitioning schemas to devise a new scheme. i.e First list partitioning with hash partitioning in each. - Common problems with Sharding: - Joins & Denormalisation: - Performing joins on a database which is running on one server is straightforward, but if DB is partitioned & spread across multiple machines, it's not feasible to perform joins that span database shards. - These joins won't be performance efficient. - Workaround is to denormalise the DB so that queries that required joins can be performed on single table. - Referential integrity: - Trying to enforce data integrity constraint suh as foreign keys in a sharded DB can be extremely difficult. Most of RDMS do not support this. - Rebalancing: - When data distribution is not uniform. - When there is lot of load on a particular Shard.

Introduction to Physical Storage
In this unit, our focus will be shifted to look at how data are physically held in secondary storage (such as magnetic or optical disks). We will not only study the most important physical organisations of data, but also discuss the management of such physical organisations. Although an ordinary user of an off-the-shelf DBMS package (such as Oracle) is unlikely to have much control over the physical aspects of the DBMS, an understanding of the materials presented in this unit is still valuable when making decisions about the performance responses of the database system. It is also important to have the knowledge in order to assess the overall storage requirements for a database application to be developed. (Chapter 6 Part 1)

Network Security - Apply Principle of Least Privileges for Access Control
Fundamentals of Computer Network Security Launch you career in cyber security. This specialization in intended for IT professionals, computer programmers, managers, IT security professionals who like to move up ladder, who are seeking to develop network system security skills. Through four courses, we will cover the Design and Analyze Secure Networked Systems, Develop Secure Programs with Basic Cryptography and Crypto API, Hacking and Patching Web Applications, Perform Penetration Testing, and Secure Networked Systems with Firewall and IDS, which will prepare you to perform tasks as Cyber Security Engineer, IT Security Analyst, and Cyber Security Analyst. Course 1 - Design and Analyze Secure Networked Systems University of Colorado System About this Course In this MOOC, we will learn the basic cyber security concepts, how to identify vulnerabilities/threat in a network system. We will apply CIA basic security services in the triage of recent cyberattack incidents, such as OPM data breach. We will learn the risk management framework for analyzing the risks in a network system, and apply the basic security design principles to protect the data and secure computer systems. We will examine the trustworthiness of programs and data installed in our systems and show the proper way to verify their integrity and authenticity. We will apply principle of least privileges for controlling the shared access given to different groups of users and system processes. On Amazon Cloud instances, we will use GnuPG software to generate public/private key pair for signing/verifying documents and open source software, and for encrypting documents. We will learn how to publish software, the related signature and release key on web server and publish public key to PGP key server for others to retrieve. We will learn Public Key Infrastructure (PKI) and Linux utility to serve as a CA for an organization, learn how to sign certificate request for clients or servers in secure email and web applications. Module 2 - Protect Data Access and Verify Source of Trust Edward Chow In this module we apply principle of least privileges for controlling the proper access given to users and system process. We will demonstrate such an access control by using an example of project document access control using the Unix file access mechanism. We use OPM data breach example to show the impact and the need for principle of adequate data protection. Trust is critical and in the center of any secure systems. We will examine the source and authenticity of the programs and data installed in systems we used daily and show the proper way to check their integrity, and verify their authenticity. Less Learning Objectives • Apply least privilege principle to provide proper access control. • Apply principle of adequate data protection to secure data • Inspect the web server identity presented by the web browser • Examine source and authenticity of the programs and data in your systems, and understand who and what we trust. • Describe the web serve certificate signing and installation process

l diversity k anonymity for privacy preserving data ( Java)
This work is an adaptation of the paper: http://ijarcsee.org/index.php/IJARCSEE/article/view/219/197 The objective is to change the view of a table containing sensitive information such that the table does not loose any significant information and yet can provide a generalized form. This is extremely important from survey point of view and to present such data by ensuring privacy preservation of the people such that under no way a particular person's identity can be obtained from partial information.
