Survey Paper on Pervasive Computing for Mobile Security

Now a day, many applications rely on the existence of small devices that can exchange information and form communication networks. And it is very challenging to provide security for such application. In a significant portion of such applications, the confidentiality and integrity of the communicated messages are of particular interest. In this work, we propose two novel techniques for authenticating short encrypted messages based on Advance Encryption crypto graphic System that are directed to meet the requirements of mobile and pervasive applications. The encryption technique have the chance of the data misusing hence we add the password based authentication technique. By using Advance Encryption algorithm we are authenticating the message which is encrypted and we are improving the decryption speed and authentication accuracy to secure the communication the proposed message authentication technique is more efficient than the previous MAC algorithms and the aim of this proposed techniques is to utilize the security that the encryption algorithm can provide to design more efficient authentication mechanisms, as opposed to using standalone authentication primitives. It provides the security to the data. However it has high risk to the sender input data while the transmission to the receiver. The process will be evaluated in the real time scenario in terms of the networking environment. The performance will be evaluated in terms of the time complexity of the whole process.
