Abstract

In this paper we analyse a technique designed to transform any discrete logarithm based cryptosystem into an identity-based cryptosystem. The transformation method is claimed to be efficient and secure and to eliminate the need to invent new identity-based cryptosystems. However, we show that the identity-based cryptosystem created by the proposed transformation method suffers from a number of security and efficiency problems.
