Pairing Free Certified Common Asymmetric Group Key Agreement Protocol for Data Sharing Among Users with Different Access Rights. [PDF]
Wirel Pers Commun, 2021 Research into a pandemic like Covid-19 needs a tremendous input of patient histories and characteristics. Patients and doctors are only willing to share these sensitive data when they are ensured that the data are solely used by legitimate research laboratories.

Dynamic asymmetric group key agreement protocol with traitor traceability [PDF]
IET Information Security, 2019 In asymmetric group key agreement (ASGKA) protocols, a group of users establish a common encryption key which is publicly accessible and compute pairwise different decryption keys. It is left as an open problem to design an ASGKA protocol with traitor traceability in Eurocrypt 2009.

Pairing free asymmetric group key agreement protocol
Computer Communications, 2022 Abstract More and more applications are nowadays distributed and rely on collaborative input. Group key protocols, enabling the construction of a common shared key, are the most evident primitive to efficiently provide the required authentication and confidentiality in the group.

Asymmetric Group Key Agreement [PDF]
International Conference on the Theory and Application of Cryptographic Techniques, 2009 A group key agreement (GKA) protocol allows a set of users to establish a common secret via open networks. Observing that a major goal of GKAs for most applications is to establish a confidential channel among group members, we revisit the group key agreement definition and distinguish the conventional (symmetric ) group key agreement from asymmetric ...

Efficient Certificateless Authenticated Asymmetric Group Key Agreement Protocol
KSII Transactions on Internet and Information Systems, 2012 Group key agreement (GKA) is a cryptographic primitive allowing two or more users to negotiate a shared session key over public networks. Wu et al. recently introduced the concept of asymmetric GKA that allows a group of users to negotiate a common public key, while each user only needs to hold his/her respective private key.

Identity-Based Authenticated Asymmetric Group Key Agreement Protocol [PDF]
International Computing and Combinatorics Conference, 2010 In identity-based public-key cryptography, an entity's public key can be easily derived from its identity. The direct derivation of public keys in identity-based public-key cryptography eliminates the need for certificates and solves certain public key management problems in traditional public-key cryptosystems. Recently, the notion of asymmetric group
