Simple Generalized Group‐Oriented Cryptosystems Using ElGamal Cryptosystem [PDF]
Informatica, 2003 Summary: In the generalized group-oriented cryptosystem, the sender can send a conditional message to a group of users such that only the specified sets of users in this group can cooperate to decrypt this message. We use an ElGamal cryptosystem and an elliptic curve ElGamal cryptosystem to achieve the purposes of generalization and group-orientation ...

Proceedings of the 2nd international conference on Security of information and networks - SIN '09, 2009 In this paper we describe a new cryptosystem we call "The Hush Cryptosystem" for hiding encrypted data in innocent Arabic sentences. The main purpose of this cryptosystem is to fool observer-supporting software into thinking that the encrypted data is not encrypted at all.
