CCA2 Secure IBE: Standard Model Efficiency through Authenticated Symmetric Encryption
We propose two constructions of chosen-ciphertext secure identity-based encryption (IBE) schemes. Our schemes have a security proof in the standard model, yet they offer performan...

An Application of the Goldwasser-Micali Cryptosystem to Biometric Authentication
This work deals with the security challenges in authentication protocols employing volatile biometric features, where the authentication is indeed a comparison between a fresh biom...

Attribute-Based Authenticated Key Exchange
We introduce the concept of attribute-based authenticated key exchange (AB-AKE) within the framework of ciphertext policy attribute-based systems. A notion of AKE-security for AB-A...

Session Corruption Attack and Improvements on Encryption Based MT-Authenticators
Bellare, Canetti and Krawczyk proposed a security model (BCK-model) for authentication and key exchange protocols in 1998. The model not only reasonably captures the power of pract...

On the soundness of authenticate-then-encrypt: formalizing the malleability of symmetric encryption
A communication channel from an honest sender A to an honest receiver B can be described as a system with three interfaces labeled A, B, and E (the adversary), respectively, where...
