Abstract:
This paper presents e-book shopping system with cryptography by using RSA algorithm. Information security is a major issue today for any company or individual who conducts business electronically. Computer applications need to protect their data from an unauthorized access. The most important security tool is cryptography. Cryptography provides stronger methods of authentication, called digital signatures and certificates. Public Key Cryptography can be used for confidentiality, authentication, or both. Digital signature is a user authentication method to prevent impersonations .The proposed system utilizes the combination of public key cryptography (RSA) algorithm and secure hash algorithm (SHA-1). In this system, cryptography is used in encryption of order information and payments information of customer and market.
