Key Privacy for Identity Based Encryption

Authors: Jason E. Holt


We define key privacy for IBE systems in terms of two
properties, indistinguishability under chosen identity attack, and
indistinguishability under chosen key generator attack. Further, we
show that the BasicIdent system in the Boneh/Franklin IBE has these
properties under chosen plaintext attack.
