González Vasco et al. extend the area of application of algorithms for the hidden number problem in 2004. Using this extension and relations among the bits in and binary fraction expansion of x mod p/p, we present a probabilistic algorithm for some trapdoor functions to recover a hidden message when an imperfect oracle is given of predicting most significant bits in hidden message. We show that computing...
In order to remedy the flaw of SRA mental poker protocol, we propose poker-resembled protocols over Zopf*p and Zopf*N, where p is a strong prime and N is the product of two strong primes. Using the results of hidden number problem, we analyze the security of these protocols and prove that when the first card drawing player is malicious, the security of the random permutation and the secret key selected...
This paper proposes an effective method of fault location based on a binary tree for optical burst switching (OBS) network. To minimize the monitoring cost, we divide the network into several monitor domains by introducing monitoring-cycle algorithms. In order to generate an exclusive code, we modify the monitoring cycle algorithm when two nodes have the same code. Through the binary tree algorithm,...
