The Design and Implementation of DSA and DSS

The proliferation of the internet and the World Wide Web as well as the widespread use of e-commerce has meant that there is a rapidly growing demand for secure electronic business transactions over insecure communication channels. In a digital environment, there is a need to protect information and data from falling into the wrong hands or from being tempered. Protecting information which has been coded in a digital format is the art of cryptography. In the past, public – key cryptosystems such as the Rivest-Shamir-Adleman or the RSA and the Digital Signature Standard or the DSS have been widely used for protecting digital information. The DSS is a component of the United States government’s Capstone program which has attempted to develop cryptography standards for United States government agencies and those private companies that want to do business with this government. This paper presents a method for implementing the DSA and the DSS.
