Abstract- Chaotic systems have numerous properties, for example: mixing property,
sensitivity to initial conditions parameters, structural complexity and deterministic
dynamics. These properties were investment in the last decade for cryptographic
applications and developments of pseudorandom number/bit generator. The paper propose
new pseudorandom number (bits) generator (PRNG) based on the Jacobian elliptic chaotic
maps and standard map. The principle of the method consists in generating binary sequence
from elliptic chaotic maps of cn and sn types. These sequence positions is permuted using
standard map. The performance of the generator is studied through conventional statistical
methods and also using the NIST test suite. The results show that the produced sequences
possess high randomness statistical properties and good security level which make it
suitable for cryptographic applications.
