SHAH: Hash Function based on Irregularly Decimated Chaotic Map
This work addresses the need for secure cryptographic hash functions, but it appears incremental as it builds on existing chaotic map techniques.
The authors tackled the problem of designing a secure hash function by proposing SHAH, based on an irregularly decimated chaotic map, and experimental results showed it achieved an admirable level of security.
In this paper, we propose a novel hash function based on irregularly decimated chaotic map. The hash function called SHAH is based on two Tinkerbell maps filtered with irregular decimation rule. Exact study has been provided on the novel scheme using distribution analysis, sensitivity analysis, static analysis of diffusion and confusion, and collision analysis. The experimental data show that SHAH satisfied admirable level of security.
