Since the “free-riding” behavior objectively exists in a P2P network, how to precisely determine the “free-riders” in the network is now a key problem. Passive testing method has been the best way of finding the potential faults on the real network at present. The observer placement problem is one of the critical problems that have been played much attention on. The problem has been also proved to...
The volume's exponential explosion problem has been the critical factor that constraints the development of the DNA computing. For the objective to decrease the DNA volume complex of the vertex cover problem which is a famous NP-complete problem, a new DNA algorithm is advanced. The new algorithm consists of a parallel reducer, a solution generator, a dense parallel searcher, a sparse parallel searcher...
Access control is a crucial security technology, it can control the legal users to sensitive resources effectively and ensure users to access relative resource. In order to compute the minimal and unique roles set which satisfy the resource access requirement, this paper proposes a DNA-based computing method to search the appropriate roles in the hybrid role hierarchy according to the user's privilege,...
