An Efficient and Secure Attribute-Based Signcryption Scheme for Smart Grid Applications
Smart Grid (SG) Ciphertext-Policy Attribute-Based Signcryption (CP-ABSC) scheme Authentication
2018/3/13
With regards to the development of modern power systems, Smart Grid (SG) as an intelligent generation of electricity networks has been faced with a tremendous attention. Fine-grained data sharing in S...
In data security, the main objectives one tries to achieve are privacy, data integrity and authentication. In a public-key setting, privacy is reached through asymmetric encryption and both data integ...
A Constructive Perspective on Signcryption Security
