Abstract:
The growth of the Internet and e-commerce has
presented businesses; these have also been exposed to the
various threats. So, network security is necessary to counter the
threats and make networks safe to use. The main security
concern of applications are addressed b cryptography. Public
key cryptography can be used for confidentiality, authentication
or both. Proving identity is called authentication.
Authentication is one of the most important factors in online
systems. RSA algorithm is extensively used in the popular
implementation of Public Key Infrastructures. Digital signature
is a user authentication method to prevent impersonations. Sales
and marketing people need to understand crypto in order to
prove the products they are selling are secure. In this paper, we
have implemented secure online shopping system by using
Public key authentication, (Rivest-Shamir-Adleman) RSA Digital
signature and Secure Hash Algorithm (SHA-512) to ensure
security of not only the data but also network of online
shopping.
