Using P systems to Solve the Discrete Logarithm Problem used in Diffie-Hellman Key Exchange Protocol

By Xiaojing Ma Zhitang Li Hao Tu

DOI: https://doi.org/10.5815/ijcnis.2009.01.04, Pub. Date: 8 Oct. 2009

The discrete logarithm problem has been used as the basis of several cryptosystems, especially the Diffie- Hellman key exchange protocol. P systems are a cluster of distributed parallel computing devices in a biochemical type. This paper presents a P system with active membranes and strong priority to solve the discrete logarithm problem used in Diffie-Hellman key exchange protocol. To the best of our knowledge, it’s the first time to solve the problem using P systems.
