TITLE | Chaos-based cryptography and STPCS stream cipher |
ABSTRACT |
Cryptography has been widely used in the present society. As a result of chaos theory and cryptography has a natural relationship, how to use the chaos theory in cryptography has become a subject of interesting. In this talk, we will brief chaos-based cryptography and propose the spatial-temporal perturbation chaotic system(STPCS) and the extend skew logistic map(ESLogist) to construct a chaos-based stream cipher, which is a fast, safe, low cost, and easy to achieve. |
