A Certificate-Based Group Signature Scheme
Haiting Du · Computers & Security · 2013
The certificate-based public key cryptography has been a new public key cryptosystem proposed by recent years.Group signature is a kind of digital signature with Multi-users.We introduce the nature of group signature into certificate-based cryptography,expanding the certificate-based signature into Multi-user environment,such as office automation,e-commerce and voting system.We propose the notion and security nature of certificate-based group signature(CBGS) and a construction of CBGS.In addition,the safety and efficiency analyses are put forward.
