Grain-v1 is an 80-bit hardware oriented stream ciphers that has been selected for the final portfolio of eSTREAM project. It has been proved experimentally that an algebraic attack can be devised against Grain-v1 which can recover almost half of its 160 internal state bits within limited resources. This attack is possible because of the algebraic structure of the equations relating the internal state...
One of the threats to watermarking security is unauthorized removal. In this paper, a framework based on extended Trusted Computer Platform to solve this problem was presented. Using Trusted Computing Platform could enhance the security of watermarking detection. The TPM as a supervisor that control the watermark detection program and only the legal one can use the secret knowledge, that is, this...
