Integration of PRESENT Cipher Model Using Bit Permutation in Wireless Sensor Network for Data Security

Security of data has become the biggest concern in recent years, due to the growing number of wireless networks. Accordingly, cryptography is becoming essential in improving data security. Encryption schemes that transforms the data into an incomprehensible shape. It plays an important role in applications such as wireless sensor networks, as most of the data is transmitted through an unsafe channel. Ultra-lightweight cryptography is one the most preferable research areas which having significant contribution towards the security aspects. There is a low power block cipher PRESENT. In this proposed work a PRESENT as reference block cipher is implemented. Here a method called PRESENT block cipher is used with key shuffling and S-Box. This method produces a 64 bits cipher text as result on input text of size 64 bits and key having of 128 bit. This developed method gives better results in comparison to other existing cipher on performance on different hardware and software platforms. With less memory requirement it produces a higher accuracy and confidentiality of the message is maintained. The proposed cipher have the better encryption time, decryption time, throughput. This proposed cipher has better resistance to crypt analysis according to avalanche effect. This proposed cipher can well be applicable for application where small traced area and low power decadence are vital design metrics.
