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.
In cryptography, Camellia is a symmetric key block cipher with a block size of 128 bits and key sizes of 128, 192 and 256 bits. It was jointly developed by Mitsubishi Electric and NTT of Japan. The cipher has been approved for use by the ISO/IEC, the European Union's NESSIE project and the Japanese CRYPTREC project.
Debdeep Mukhopadhyay is an Indian cryptographer and professor at the Department of Computer Science and Engineering of the Indian Institute of Technology Kharagpur.He was awarded the Shanti Swarup Bhatnagar Award for Science and Technology, [1] [2] [3] the highest science award in India, in 2021 for his contributions to micro-architectural security and cryptographic engineering.
The development of CrypTool started in 1998. Originally developed by German companies and universities, it is an open-source project since 2001. [2]Currently 4 versions of CrypTool are maintained and developed: The CrypTool 1 (CT1) software is available in 6 languages (English, German, Polish, Spanish, Serbian, and French).
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).
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 ...
