Secure Hybrid Encryption from Weakened Key Encapsulation
We put forward a new paradigm for building hybrid encryption schemes from constrained chosen-ciphertext secure (CCCA) key-encapsulation mechanisms (KEMs) plus authenticated symmet...

Generic One Round Group Key Exchange in the Standard Model
Minimizing complexity of group key exchange (GKE) protocols is an important milestone towards their practical deployment. An interesting approach to achieve this goal is to simplif...

On the Security of Tag-KEM for Signcryption
Signcryption tag-KEM (Key Encapsulation Mechanism with a tag) is an authenticated tag-KEM for generic construction of hybrid signcryption. Signcryption tagKEM allows the sender to...

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...

Strongly Secure Authenticated Key Exchange from Factoring, Codes, and Lattices
Abstract. An unresolved problem in research on authenticated key exchange (AKE) is to construct a secure protocol against advanced attacks such as key compromise impersonation and ...
