摘要：In this paper we propose a technique to enhance the security of forward digital signature.In this enhancement scheme the private key and the public key changes at random intervals of time ,if there is a communication between two users. If there is no communication then the keys will not be changed. This technique is mainly based on elliptic curve cryptography and Digital signature algorithm. By using this enhancement scheme the attacker cannot get the older or future signatures even if the private key is compromised.The attacker can only know the signature at that session only.This scheme is more secure and it is proved practically.
