Behind multiple trapdoors: A cryptographic commitment scheme for establishing secure communications

Borja Gómez

Abstract: This paper introduces a cryptographic commitment using multiple platform groups where the attacker must solve multiple instances of the Discrete Logarithm Problem to break the scheme. The goal is that Alice and Bob establish a secret communication after verifying a finite set of values that have been computed using multiple trapdoor-permutation functions. Moreover, applicable cryptanalytic techniques and procedures that entirely define this scheme are discussed
