An improved sign-in scheme based on RSA cryptosystem

This paper presents an improved sign-in scheme base on public key cryptosystem. In the program, the client uses JavaScript to implement the RSA´s encryption and decryption algorithms, using Java implement key pairs generation and management, encrypt and decrypt the ciphertext in server side, combine the above technologies to implement the scheme, and illustrate the key codes, as a result, it not only reduce the load of system, but also enhance the security of system.
