Identity-based encryption algorithm using hybrid encryption and MAC address for key generation

Abstract

In today’s world, secured communication is what every field wants. But due to the escalation of theft and unauthorized access to the data, the need for new encryption algorithms has also gone high. This paper proposed a hybrid encryption scheme which uses ElGamal key exchange algorithm and Genetic algorithms. In this scheme, the users share seventeen 16-bit keys, random in nature, using the ElGamal algorithm, which is used to calculate a shared key. Along with this shared key and MAC(Medium Access Control) addresses of both sender and receiver(MAC is used as it is a unique identifier attached to a network adapter or system), a final key is generated through a 10-round algorithm. Further, this final key is used for data encryption using Genetic algorithms. A new key is generated for each communication session between sender and receiver. The proposed technique shows that it is resistant to most of today’s known and common attacks.
