Attribute-based authenticated key agreement protocol supporting revocation

Tongxin xuebao, 2014
Revocation is a crucial issue for the practical use of attribute-based authenticated key agreement (ABAKA) protocols. A new ABAKA protocol supporting revocation was proposed.

Cryptanalysis of a multi-party quantum key agreement protocol with single particles

, 2013
Recently, Sun et al. [Quant Inf Proc DOI: 10.1007/s11128-013-0569-x] presented an efficient multi-party quantum key agreement (QKA) protocol by employing single particles and unitary operations.

Key Agreement Using Statically Keyed Authenticators [PDF]

, 2004
A family of authenticators based on static shared keys is identified and proven secure. The authenticators can be used in a variety of settings, including identity-based ones. Application of the authenticators to Diffie-Hellman variants in appropriate groups leads to authenticated key agreement protocols which have attractive properties in comparison ...

Novel 5G Authentication Protocol to Improve the Resistance Against Active Attacks and Malicious Serving Networks

IEEE Access, 2019
The security of mobile communication largely depends on the strength of the authentication key exchange protocol. The 3rd Generation Partnership Project (3GPP) Group has standardized the 5G AKA (Authentication and Key Agreement) protocol for the next ...

Communication Complexity of the Secret Key Agreement in Algorithmic Information Theory

, 2020
It is known that the mutual information, in the sense of Kolmogorov complexity, of any pair of strings x and y is equal to the length of the longest shared secret key that two parties can establish via a probabilistic protocol with interaction on a ...

Efficient and Secure Temporal Credential-Based Authenticated Key Agreement Using Extended Chaotic Maps for Wireless Sensor Networks

Sensors, 2015
A secure temporal credential-based authenticated key agreement scheme for Wireless Sensor Networks (WSNs) enables a user, a sensor node and a gateway node to realize mutual authentication using temporal credentials.

The Sender-Excited Secret Key Agreement Model: Capacity, Reliability and Secrecy Exponents

, 2013
We consider the secret key generation problem when sources are randomly excited by the sender and there is a noiseless public discussion channel. Our setting is thus similar to recent works on channels with action-dependent states where the channel state

Concurrent Two-Party Key Exchange With Forward Unlinkability in Internet of Drones

IEEE Access
By the drone capturing attacks, the adversaries can extract the long-term secret keys stored in the drones. Therefore, it is necessary to consider forward secrecy and forward unlinkability to minimize the damage by the drone capturing attacks.

Secret Key Agreement from Correlated Gaussian Sources by Rate Limited Public Communication

, 2010
We investigate the secret key agreement from correlated Gaussian sources in which the legitimate parties can use the public communication with limited rate.
