Abstract:
Public key cryptography is an important aspect in Information Security. Since RSA is the most widely used and
accepted public key algorithm so far, many proven applications based on the RSA algorithm are widely used around
the world. At present, applications of the Elliptic Curve Cryptography have been arisen as ECC has become a
competing algorithm to RSA. Therefore, many comparisons between the two algorithms have been identified for
various applications. This research focuses on applying Public Key Cryptography for user authentication in online
transactions. Authentication is carried out generating biometric base digital signatures. The process of generating
the digital signature is a combination of biometric signature and public key cryptography. The introduced new
technique was implemented for algorithms ECC and RSA, and then conducted a strength comparison between two
algorithms in order to observe the most suitable algorithm for the biometric digital signature generation.
