As the core of cryptography, hash function is one of the basic techniques for information security. During the last few years, considerable effort has been devoted to research on chaos-based hash functions. Nevertheless, the corresponding analysis of them lag far behind. In this paper, a new e...
A hash is a one-way function that transforms data in such a way that, given a hash result (sometimes called a digest), it is computationally infeasible to produce the original message. Besides being one-way, hash functions have some other basic properties: ▪ They take an input of any ...
Lyapunov exponents, a densely distributed bifurcation diagram, and a phase space trajectory diagram, which provides superior dynamic complexity and thereby shows high sensitivity to initial conditions and control parameters, and demonstrates remarkable applicability in fields such as hash function construction...
Hash function.A hash algorithm alters or digests the message once more. HMAC usesgeneric cryptographic hash functions, such as SHA-1, MD5, or RIPEMD-128/60. A pair using this system must agree on: Secret keys.They must have a way to decode messages they get. A secret key handles this...

In the data security field, a modular cryptographic hash function process is embodied in a computer system or hardware (circuitry). The process is based on the mode of operation of
Elliptic curve hash functions are provided which do not require a pre-existing hash function, such as that required by the MuHash. The elliptic curve hash functions can be built fro
