An Approach for SMS Security using Authentication Functions

algorithm like Diffie-Hellman can be used to encrypt the SMS message in M-commerce or mobile banking system. Password key exchange protocol based on Diffie- Hellman key exchange algorithm allows users to exchange a secret key that can be used in message encryption. The security of this protocol can be increased by using the MAC (message authentication code) or hash function with the encryption. These functions act as an error detecting code or...
