As technology is growing, mobile devices are replacing the traditional systems, and it is increasing the ease of access; but at the cost of resource availability, these lightweighted devices come with lesser memory and processing power. The network available for such devices is often wireless; hence, data transmission rate is generally slower than that of traditional system. Thus, in order to provide security measures for such devices, various parameters need to be considered. The security mechanism should be fast as well as efficient enough to overcome those limitations. In order to implement security over network, various techniques can be used, and cryptography is one of the most commonly used methods. It converts the readable plain text into a non-readable format known as cipher text. There are various techniques to implement cryptography. The proposed system is using an enhanced cryptographic technique which will be secure as well as efficient. It uses compression prior to encryption; hence, both time and space are reduced for further operations, and as a result, both time and space are saved which play a vital role in enhancing the performance, especially when it is a mobile device. In order to enhance, the security file is converted into byte code and then it is broken into chunks which are further treated with XOR operation to increase the randomness of data. Several passes of ex-or are performed to make data as random as possible so as to make it less vulnerable against brute force attack. In this way, the proposed system enhances the security as well as performance.
