Heterogeneous hybrid signcryption for multi-message and multi-receiver. [PDF]
PLoS ONE, 2017 To achieve secure communication in heterogeneous cryptography systems, we present a heterogeneous hybrid signcryption scheme. The proposed scheme allows a sender in an identity-based cryptography system to send multi-message to multi-receiver in a ...

On the Security of Certificateless Signature Schemes
International Journal of Distributed Sensor Networks, 2013 Wireless Sensor Network (WSN) has proved its presence in various real time applications and hence the security of such embedded devices is a vital issue. Certificateless cryptography is one of the recent paradigms to provide security.

Certificateless Public Key Cryptography [PDF]
, 2003 This paper introduces the concept of certificateless public key cryptography (CL-PKC). In contrast to traditional public key cryptographic systems, CL-PKC does not require the use of certificates to guarantee the authenticity of public keys. It does rely

Modelling and simulation of a biometric identity-based cryptography [PDF]
, 2014 Government information is a vital asset that must be kept in a trusted environment and efficiently managed by authorised parties. Even though e-Government provides a number of advantages, it also introduces a range of new security risks.

IET Blockchain, Volume 6, Issue 1, January/December 2026.ABSTRACT The proliferation of Internet of Things (IoT) devices has created an urgent demand for secure, scalable and interoperable data‐sharing architectures. Centralized paradigms exhibit single points of failure, inadequate access control and limited transparency, rendering them structurally misaligned with the distributed nature of IoT deployments ...

An Efficient Heterogeneous Signcryption Scheme from Certificateless to Identity-based Cryptosystem
MATEC Web of Conferences, 2017 The heterogeneous signcryption can not only realize the confidentiality and un-forgeability of the information transmission between different public key cryptography environments, but also reduce the communication cost. The proposed scheme uses bilin-ear

IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes a novel lightweight certificateless public key authentication with keyword search (CPAEKS) scheme tailored for IIoT environments, effectively addressing data confidentiality and retrieval efficiency. The scheme resists frequency analysis attacks, removes reliance on bilinear pairings, and eliminates key escrow and certificate ...
