The survey of various techniques & algorithms for SMS security

Abstract

Now days, Message authentication is an important security tool. But, without some security mechanism, it is difficult to send data in secure manner. Most popular shortest and cheapest textual form of communication is short message service (SMS). Cryptography is the one of the main categories of computer security that converts information from its normal form into an unreadable form by using Encryption and Decryption Techniques. To ensure the security of the texts which is sent, many encryption algorithm are available. This paper will focus on message security and to secure the text data while transmitting in the network. The data which is to be transmitted from sender to receiver in the network must be encrypted using the encrypted algorithm.). Symmetric key algorithm reduces the problem of computational overhead and to the calculation of algorithm and improves the performance of encryption. The proposed paper is to provide more efficient authentication mechanisms for textual data. The proposed review paper presents a review of security techniques for SMS and a performance comparison between most common encryption algorithms like DES, 3DES, RC4, Blowfish and AES (Rijndael)
