hash function

Research and Improvement of Computing Algorithms for Calculating the Trigonometrical Coefficients of the Hashing Algorithm MD5

The paper examines the problems of ensuring the authenticity of messages, as well as analyzes the modern requirements for hash functions and the problems of designing algorithms for calculating hash functions.

Data protection of biometric authentication for remote access to a bank account

This article is devoted to the hash function that provides closure of biometrics in information networks for remote access to client account. There is proposed hash function which is described as a table of numbers. Verification of sustainability of cryptographic hash functions is performed. The session key for the hash is determined by the sequence of biometric data. The protocol of mutual authentication of a client and the server of payment system is given. The number of client’s safe applications to ATM is estimated.
