Modified ID-Based Public key Cryptosystem using Double Discrete Logarithm Problem

Author 1: Chandrashekhar Meshram

In 1984, Shamir [1] introduced the concept of an identity-based cryptosystem. In this system, each user needs to visit a key authentication center (KAC) and identify him self before joining a communication network. Once a user is accepted, the KAC will provide him with a secret key. In this way… Read full abstract & cite →
