Abstract -
Content distribution in network sometimes may be vulnerable henceforth unauthorized users can inject “bogus” data to corrupt the content during its distribution process in order to deplete the network resource. The direct application of network coding may be insecure. Content verification is the important and practical issue when maintaining integrity of the content. While random linear networking coding is used, it is impracticable for the source of the content to sign all the data, and also the traditional methods such as “hash and sign” are no longer applicable. This is achieved by on the fly verification, which employs a classical homomorphic hash function. In this method content is spitted and hashing is applied. Hashed content is sent to the destination through peer to peer network. Key is sent to the destination directly from the source. Without the key unauthorized users finds difficult to modify the content. Hence the content is secured, however this technique is very complex to be applied to network coding because of high computational and communication overhead. We analyzing this issue further by carefully for different types of overhead, and we propose methods to reducing both communication and computational cost, and also to achieving that providing provable security at the same time.
