Present a content integrity service for objects in a digital museum, especially for objects stored in long-term digital archives. The goal of the service is to demonstrate that the information in the archive is authentic and has not been unintentionally or maliciously altered even after its bit representation in the archive has undergone one or more transformations. The service is based on one-way...
With the increasing scale of software and the exploding amount of data, software performance problem has become more and more serious, drawing more and more people to study the way of testing softwarepsilas performance. Although there are many performance test methods focusing on B/S structured system, other systems are ignored. In this paper, the common performance test procedure is given first,...
In this paper, an authenticated deterministic secure quantum communication protocol based on entanglement swapping is presented. The users' identity will be authenticated, and only legitimate users can anticipate the communication even though there are no quantum communication channels between them. The authentication center acts as the server of modern application system, and the users is like those...
Image unchangeable coefficient rule in discrete cosine and wavelet transformation was proved when it was scrambled in spatial domain. Based on the constructed composite chaotic iterative dynamic system, whose invariant distribution density was one, and in order to initialize for composite chaotic iterative dynamic system, it put forward two construced functions using image scramble constant as input...
