The design philosophy of authenticated system based upon digital signature algorithms and the implementation of DSA-Digital Signature Algorithms with SHA-1 (Secure-Hash Function) using Java language for computer networking applications are presented.
This paper presents, the design philosophy of authenticated system based upon digital signature algorithms and the implementation of DSA-Digital Signature Algorithms with SHA-1 (Secure-Hash Function) using Java language for computer networking applications. Digital Signature Algorithms have been used for PKI-Public Key Infrastructure applications which are necessary for e-commerce. DSA with SHA-1 is a FIPS standard approved by NIST, USA, therefore, it is considered for implementation. This standard algorithm is implemented in Java an object oriented, network Savvy and platform independent computer language. Graphical user interface-GUI is also designed for input. The future work will be to generate digital certificates using X.509 standard.
