This paper proposes two one-round authenticated group key exchange protocols from newly
employed cryptographic invariant maps (CIMs): one is secure in the quantum random oracle …

We present the first constant-round, tree-based, group key exchange protocol based on
SIDH with logarithmic-order communication and memory complexity, where the only …

While instant messaging systems bring convenience to people's lives and work, they also
make it easier for malicious users to discuss and plot illegal activities. Therefore …

Dual-receiver encryption (DRE) is a special form of public key encryption (PKE) that allows a
sender to encrypt a message for two recipients. Without further properties, the difference …

The 3PAKE (Three-Party Authenticated Key Exchange) protocol is a valuable cryptographic
method that offers safe communication and permits two diverse parties to consent to a new …

In this paper, we propose a two-round dynamic multi-cast key distribution (DMKD) protocol
under the star topology with a central authentication server. Users can share a common …

We present the first constant-round, tree-based, group key exchange protocol based on
SIDH with logarithmic communication and memory complexity, where the only previous …

With the rapid advancement of Mobile Internet (MI) and wireless networks, mobile devices
have become very essential tools for people's daily tasks as they can provide a wide range …

We propose a group key exchange compiler using any two-party key exchange for which the
shared key space is the subset of a group and whose security reduces to a decisional hard …

We present the first constant-round, multicast, tree-based Ring-LWE group key exchange
protocol with logarithmic communication and memory complexity. Our protocol achieves …
