A Low-Cost Solution for Frequent Symmetric Key Exchange in Ad-hoc Networks
: Next to authentication, secure key exchange is considered the most critical and complex issue regarding ad-hoc network security. We present a low-cost, (i.e. low hardware-complex...

Fully Secure Functional Encryption: Attribute-Based Encryption and (Hierarchical) Inner Product Encryption
In this paper, we present two fully secure functional encryption schemes. Our first result is a fully secure attribute-based encryption (ABE) scheme. Previous constructions of AB...

Efficient Constructions of Deterministic Encryption from Hybrid Encryption and Code-Based PKE
Abstract. We build on the new security notion for deterministic encryption (PRIV) and the PRIV-secure schemes presented by Bellare et al at Crypto'07. Our work introduces: 1) ...

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...
