In this paper, we are describing concept to improve security of wireless sensor networks [1] using checksum one way function called hash code. Along with the security we are also performing file compression using compression techniques like zip input and output streams to reduce the storage cost. In existing technique security is provided using cryptography techniques but still attackers [5] can manage to get original data by hacking keys and eavesdrop (identify and alter packet) packet [7]. Cryptography techniques require heavy computation and can be hack by attackers. To improve security author is using reluctant checksum (hash code) [4] while sending data and only destination can decode and compare data. While sending data first corrupted data will be added to message and only source and destination may know how to get original data from corrupted data and message integrity will be checked using UMAC hash code. Sender will generate checksum code and send code with message to receiver and then receiver once again generate code on received message, if same hash code generated [4] then message was not eavesdrop or alter by attacker. By adding corrupted messages attacker will have no clue to identify which part of message is original and which part is corrupted and without getting original message attacker cannot alter packet and security[6] will be improve. Furthermore, we can add file compression concept to save the memory and processing time in our design with this the storage occupied by compressed file will be lesser than the original file. |
