Cryptology Research Society of India (CRSI) is a scientific organisation that supports research in India on cryptography, data security, and related fields. [1] [2] The organisation was founded in 2001. [2] CRSI organises workshops and conferences about cryptology. [3]
It is one of the institutes which comes under the purview of the National Technical Research Organisation. [2] The other one is the National Critical Information Infrastructure Protection Centre. It was envisioned to house simulation laboratories, and digital fortress laboratories for financial security and design.
Cryptography is also a branch of engineering, but an unusual one since it deals with active, intelligent, and malevolent opposition; other kinds of engineering (e.g., civil or chemical engineering) need deal only with neutral natural forces. There is also active research examining the relationship between cryptographic problems and quantum physics.
Attribute-based encryption is a generalisation of public-key encryption which enables fine grained access control of encrypted data using authorisation policies.The secret key of a user and the ciphertext are dependent upon attributes (e.g. their email address, the country in which they live, or the kind of subscription they have).
The Cryptology ePrint Archive is an electronic archive of new results in the field of cryptography, maintained by the International Association for Cryptologic Research. It contains articles covering many of the most recent advances in cryptography, that did not necessarily undergo any refereeing process. [1]
Computational hardness assumptions are of particular importance in cryptography. A major goal in cryptography is to create cryptographic primitives with provable security. In some cases, cryptographic protocols are found to have information theoretic security; the one-time pad is a common example. However, information theoretic security cannot ...
Countries may wish to restrict import of cryptography technologies for a number of reasons: Imported cryptography may have backdoors or security holes (e.g. the FREAK vulnerability), intentional or not, which allows the country or group who created the backdoor technology, for example the National Security Agency (NSA), to spy on persons using the imported cryptography; therefore the use of ...
PRNGs are central in applications such as simulations (e.g. for the Monte Carlo method), electronic games (e.g. for procedural generation), and cryptography. Cryptographic applications require the output not to be predictable from earlier outputs, and more elaborate algorithms, which do not inherit the linearity of simpler PRNGs, are needed.
