Efficient certificateless multi-receiver anonymous signcryption scheme
Tongxin xuebao, 2016 To solve the private key escrow problem of identity-based multi-receiver signcryption schemes,the security model for multi-receiver signcryption scheme was constructed,and then a certificateless multi-receiver signcryption scheme based on ECC was ...

Signcryption schemes with insider security in an ideal permutation model
Journal of Mathematical Cryptology, 2019 Signcryption aims to provide both confidentiality and authentication of messages more efficiently than performing encryption and signing independently. The “Commit-then-Sign & Encrypt” (CtS&E) method allows to perform encryption and signing in parallel ...

Improved Identity-Based Signcryption [PDF]
, 2005 Identity-based cryptography is form of public-key cryptography that does not require users to pre-compute key pairs and obtain certificates for their public keys. Instead, public keys can be arbitrary identifiers such as email addresses. This means that the corresponding private keys are derived, at any time, by a trusted private key generator.

IET Communications, Volume 20, Issue 1, January/December 2026.Federated learning (FL) enables collaborative model training without collecting user data but faces security risks such as privacy breaches, poisoning, and free‐rider attacks. To address these challenges, we propose DRFL, a defense mechanism integrating dual encryption, reputation evaluation and blockchain to enhance security and transparency ...

Formal Proofs for the Security of Signcryption [PDF]
Journal of Cryptology, 2002 Signcryption is an asymmetric cryptographic method that provides simultaneously both message confidentiality and unforgeability at a low computational and communication overhead. In this paper we propose realistic security models for signcryption, which give the attacker power to choose both messages/signcryptexts as well as recipient/sender public ...

IET Communications, Volume 20, Issue 1, January/December 2026.This paper presents a lightweight mutual authentication protocol for VANETs that integrates SDN, edge computing, and ECC to achieve low‐latency, scalable, and privacy‐preserving vehicle communication. The proposed system reduces authentication delay and computational overhead while supporting batch verification and conditional identity traceability ...

Identity Based Generalized Signcryption Scheme in the Standard Model
Entropy, 2017 Generalized signcryption (GSC) can adaptively work as an encryption scheme, a signature scheme or a signcryption scheme with only one algorithm. It is more suitable for the storage constrained setting.
