Key dependent message security

Tal Malkin, Isamu Teranishi, Moti Yung
2011 Proceedings of the first ACM conference on Data and application security and privacy - CODASPY '11  
An encryption scheme is Key Dependent Message (KDM) secure if it is secure even against an attacker who has access to encryptions of messages which depend on the secret key.  ...  In this paper we review the definition, and survey recent results and applications of KDM security.  ...  Circular security has two meanings: the original definition in [17] is equivalent to clique security, but it sometimes refers to a weaker security notion (Strictly Circular Security): {Enc(ski, sk i+  ...
