Security analysis of a one-way hash function based on spatiotemporal chaos
Shi-Hong Wang, Peng-Yang Shan · Chinese Physics B · 2011
The collision and statistical properties of a one-way hash function based on spatiotemporal chaos are investigated. Analysis and simulation results indicate that collisions exist in the original algorithm and, therefore, the original algorithm is insecure and vulnerable. An improved algorithm is proposed to avoid the collisions.
