Secure Proxy Digital Signature Scheme using Digital Signature Standard with Random Key Generation Process

Now a days digital signature schemes stress on secure, authentication and verification mechanism of electronic signature used in electronic transaction system. In this sequence proxy digital signature may play an important role to achieve the security goals. Proxy Digital signature is the process of authorized signatory of the document by one person on behalf of other one. None of the proxy signature schemes which have been proposed up to now, are based on Digital Signature Standard (DSS) cryptosystem with changing random key values dynamically. Therefore, these proposals have unavoidably been considered infeasible because of obvious security weaknesses, so they suffer from new attacks. Consequently, I propose a new proxy signature scheme which combines the Digital Signature Standard (DSS) properties with random key generation. Finally, a DSS proxy digital signature system is implemented and its time complexity is analyzed.
