Implementation of a randomness test to evaluate chaos-based cryptography

Undegraduate poster related to PARSEC project presented at the 26º SIICUSP (2018) The main goal of this scientific initiation project is the implementation of a cryptosystem based on the k-logistic map PRNG [1]. To achieve such goal, the pseudo-randomness of the algorithm must be verified, which is being done in parallel to the crypto-system’s implementation. Thus, the goal of this work is to implement a randomness test sensitive enough to accurately measure the pseudo-random properties of the given chaotic system.
