Leakage-Resilient Hybrid Signcryption in Heterogeneous Public-key Systems

Informatica
Signcryption integrates both signature and encryption schemes into single scheme to ensure both content unforgeability (authentication) and message confidentiality while reducing computational complexity. Typically, both signers (senders) and decrypters (

Efficient signcryption scheme based on Cocks’ identity cryptosystem

Tongxin xuebao, 2020
Most of the existing identity-based signcryption schemes are based on bilinear or multilinear pairing operations construction.To solve the problem of low efficiency caused by complex pair operation, a new efficient signcryption scheme based on the ...

Multipurpose Identity-Based Signcryption [PDF]

, 2003
Identity-Based (IB) cryptography is a rapidly emerging approach to public-key cryptography that does not require principals to pre-compute key pairs and obtain certificates for their public keys—instead, public keys can be arbitrary identifiers such as email addresses, while private keys are derived at any time by a trusted private key generator upon ...

A Novel Efficient and Secure Privacy-Preserving Scheme for Smart Grid Based on HECC

IEEE Access
Smart Grid (SG) is an electricity distribution network that monitors energy flow from the point of generation to its final location. The SG can save electricity usage and improve service quality at the same time.
