ABSTRACT
It has been shown that the encrypted information or ciphertext produced by symmetric-key block ciphers with Electronic codebook mode is vulnerable to ciphertext searching, replay, insertion and deletion because it encrypts each block independently. To compensate for this, each block of the encrypted information should be encrypted dependently. The encrypted information should be operated with a special mode. The operation mode should be changed. This paper analysis what an operational mode of block ciphers needs to feedback exactly and proposes a simple real-time changing operation mode technique that extends the existing mode changing opportunity. The new change operation mode technique considers the sign differences between the intra-feedback information and the public-feedback information, and then adaptively determines the corresponding change operation mode factor for each data block. This mode hopping technique for mobile streaming security is highly suitable for recent block computing in future various environments.

    A black hole attack is one of the most serious attacks in mobile ad hoc networks. A malicious node can act as if it has a valid route to a destination and then respond with a false Route Reply (RREP) message to the source, when it receives a Route Request (RREQ). Then the malicious node absorbs...
