Tame logarithmic signatures of abelian groups

Journal of Mathematical Cryptology, 2017
The security of the asymmetric cryptosystem MST1{{}_{1}} relies on the hardness of factoring group elements with respect to a logarithmic signature. In this paper we investigate the factorization problem with respect to logarithmic signatures of abelian ...

Converting pairing-based cryptosystems from composite to prime order setting – A comparative analysis

Journal of Mathematical Cryptology, 2018
Composite order pairing setting has been used to achieve cryptographic functionalities beyond what is attainable in prime order groups. However, such pairings are known to be significantly slower than their prime order counterparts.

Revocable policy-based chameleon hash using lattices

Journal of Mathematical Cryptology
A chameleon hash function is a type of hash function that involves a trapdoor to help find collisions, i.e., it allows the rewriting of a message without modifying the hash.

Investigation of metabelian platform groups for protocols based on (simultaneous) conjugacy search problem

Journal of Mathematical Cryptology
There are many group-based cryptosystems in which the security is related to the conjugacy search problem or the simultaneous conjugacy search problem in their underlying platform groups.
