WebDynamical degradation occurs when chaotic systems are implemented on digital devices, which seriously threatens the security of chaos-based cryptosystems. The existing solutions mainly focus on the compensation of dynamical properties rather than on the elimination of the inherent biases of chaotic systems. In this paper, a unidirectional hybrid control … Web(quantum) random oracles are contrived and unlikely to be constructed in practice. 3. No schemes with security reductions in the (Q)ROM have been shown to have vulnerabilities stemming from the failure of hash functions to approximate a (quantum) random oracle. We first describe the ROM, the QROM, and their nontrivial relationship.
