ABSTRACT:
A computer readable medium storing executable code to generate an identity-based encryption key includes executable code to specify a master key, receive an identity-based string and execute a function that processes the master key and the identity-based string to produce a seed. The seed is then used to produce an identity-based encryption key interoperable with a deployed public key cryptosystem.
