Query: Commutative-like Encryption: A New Characterization of ElGamal   Commutative encryption is a useful but rather strict notion in cryptography.
In this paper, we deny a loose variation of commutative
encryption-commutative-like encryption and give an example: the generalization
of ElGamal scheme. The application of the new variation is also discussed.
