ABSTRACT
In this paper the realization of one algorithm for digital signature, DSA (Digital Signature Algorithm), is presented. In the algorithm, for calculating the variables needed to generate public and private key, one-way hash function, SHA (Secure Hash Algorithm), is used. A method of realization of SHA and DSA is presented, and the time required to digitally sign messages of different sizes and time required to generate the keys are measured. The results are compared with the analogous result based on another software implemented system for digitally signing with hash function and RSA algorithm.
