Abstract
Abstract: A wireless sensor network is usually composed of a large number of spatially distributed autonomous sensor nodes. Advancement in the field of modern communication networks especially in the wireless network dramatically improved their accessibility,affordability and accuracy. The eavesdropping is a serious security threat to a WSN since this attack is a prerequisite to other attacks. Avoiding the major threat called eavesdropping,cryptographic techniquies are to be used. Reexamine the notion of security,accessibilty,affordability and confidentiality of the WSN, combines Shannon's cypher method and Ford-Fulkerson algorithm together with one time pad system. The idea behind the algorithm is simple. According to Ford-Fulkerson algorithm,as long as there is a path from start node to end node with available capacity on all edges in the path, send flow along one of these paths,find another path and so on.That path is called augmented path. Through this non-cooperative eavesdropping can be avoided. Ford-Fulkerson algorithm can be used along with the one time pad scheme. The one time pad scheme is a binary additive stream cipher, where stream of truly random keys are generated and then combined with the plaintext for encryption or with the ciphertext for decryption using exclusive OR addition. Because of the three important properties of this scheme one time pad scheme can accepted as the most prominent security providing mechanism,properties such as: key must be as long as the plain text, key must be truly random and key must only be used once. Main disadvantage is that one time pad scheme has a serious threat to Brute force attack. Thus for avoiding the brute force attack combines Ford-Fulkerson and ZKP along with the AES algorithm.
