Circular and KDM Security for Identity-Based Encryption
We initiate the study of security for key-dependent messages (KDM), sometimes also known as “circular” or “clique” security, in the setting of identity-based encryption (I...

Ideal Key Derivation and Encryption in Simulation-Based Security
Abstract. Many real-world protocols, such as SSL/TLS, SSH, IPsec, IEEE 802.11i, DNSSEC, and Kerberos, derive new keys from other keys. To be able to analyze such protocols in a com...
