IRJET-Implementing Encryption Algorithm for Addressing GSM Security Issues (original) (raw)

The Advanced encryption standard (AES) is an algorithm that was formerly considered to be the most popular method for private key encryption. AES is still appropriate for moderately secured communication. In this paper we have implemented AES algorithm for voice data encryption and decryption by using the MATLAB. The GSM speech service is secure up to the point where speech enters the core network. However to achieve end-to-end security it is desired that the GSM subscriber, not the network operator controls the encryption on the speech channel. A new approach of encryption at the user-end is introduced. The MATLAB Software was used as program module of the system implementing the encryption and decryption algorithm.
