Research on Attribute-based Proxy Signature Technology

Digital signature is one of the important applications of asymmetrical cryptography in information security domain.Proxy digital signature is one of the technical problems of digital signature.Starting from the concept and process of digital signature, this paper introduces the definition of attribute-based signature, and then designed the proxy digital signature scheme, and one of the seven kinds of algorithm is studied in detail.Finally, this article discussed the security of proxy digital signature.
