Parallel Generator of Discrete Sequences using Multi-Threading Approach
Résumé
We implemented in efficient manner (time computation, software security) a generator of discrete chaotic sequences (GDCS) by using multi-threaded approach. The chaotic generator is implemented in C language and parallelized using the Pthread library. The resulting implementation achieves a very high bit rate of 1.45 Gbps (with delay =1) on 4-core general-purpose processor. Security performance of the implemented structure is analyzed by applying several software security tools and statistical tests such as mapping, auto and cross-correlation, and NIST test. Experimental results highlight the robustness of the proposed structure against known cryptographic attacks.
