Encoding-Free ElGamal Encryption Without Random Oracles
[chapter]
2006
Lecture Notes in Computer Science
ElGamal encryption is the most extensively used alternative to RSA. Easily adaptable to many kinds of cryptographic groups, ElGamal encryption enjoys homomorphic properties while remaining semantically secure providing that the DDH assumption holds on the chosen group. Its practical use, unfortunately, is intricate: plaintexts have to be encoded into group elements before encryption, thereby requiring awkward and ad hoc conversions which strongly limit the number of plaintext bits or may
