Secure file transmission using byte rotation algorithm in network security

Secure file transmission from one android user to another android user is important issue in network security. Byte rotation algorithm (BRA) and AES algorithm solve the problem of secure file transmission using encryption and decryption. In this paper we have introduced BRA for file encryption and decryption within minim delay. These algorithms improves the security and reduce time for process of file encryption and decryption. To provide security for different types of file like image, text, audio and video using BRA. Results are taken using Net Bean java complier for AES and BRA. Compare result for various parameters like BRA and AES encryption time as well as decryption time. To improve file security using random key generation (128bit) is used. User can set time and frequency during file transmission. When these conditions are satisfied file and key used for encryption will be deleted.
