This paper proposes a new ID‐based cryptographic scheme for implementing public‐key cryptosystems and signatures. Instead of generating and publishing a public key for each user, the ID‐based scheme permits each user to choose his name or network address as his public key. This eliminates the need of a large public‐file and the exchange of private or public keys. The major advantage of the ID‐based cryptosystems is that the number of users can be exteneded to t*L users without decreasing the system security when users conspire, where L is the number of the system's secrets and t is the number of factors in p ‐ 1.
