Data Encryption of Audio File by using AES and RSA Algorithms

In this age of universal electronic connectivity is needed to protect data and resources from disclosure, to guarantee the authenticity of data and messages, and to protect systems from network-based attacks. The disciplines of cryptography and network security have matured, leading to the development of practical, readily available applications to enforce network security. The cryptography is one of the ways to be data secure.This paper intends to design a security protocol using hybrid encryption technique for wave files. The hybrid encryption technique is a combination of both symmetric and asymmetric cryptographic techniques. The encryption algorithms are more secured depends on the key value and its size. But, the key distribution is major problem. The various protocols are currently given the solution. The new protocol solves the key management problem using key servers. This paper presents the encryption of wave file by AES algorithm and RSA algorithm is used to secure the AES key
