With the rapid pace of globalization and outsourcing, supply chain integrity of ICT system is gaining more and more attentions. Integrity of ICT Supply Chain has a slightly different focus from network security. Due to the increasing complexity and formidable cost and timing, it's by no means enough to guarantee the integrity of a modern ICT product through technical testing and vendor screening....
Interior point method (IPM), as one of the most efficient methods, is being extended to solve different types of optimization problems in electric power domain. In this paper, the nonlinear OPF problem, formulated with a rectangular coordinate form, is solved using the enhanced multiple predictor-corrector interior point method, which is combined with the selection of the optimal composite direction...
Basing on the discourse about traditional model of the securities markets pricing mechanism, and considering the reality of the "absence of the liquidity supplier" in our country's security markets, this paper works out a dynamic stochastic matching pricing model basing on Markov tactics of the traders. And by the empirical testing, it vitrifies the basic hypotheses of the model.
We propose a public key homomorphism in real domain based on a modified ElGamal. It can encrypt addition, subtraction, multiplication, and division operation in real domain. It solves all problems in Xing et al.psilas method based on Lee et alpsilas homomorphism and can be applied in many applications.
The nanoscale technology makes the design concept of the sea of processors possible in the coming billion transistor era for high performance implementations. In order to solve the scalability, complexity and timing problem of the communication between these processors in a large scale SoC (System on a Chip) implementation, the NoC (Network on a Chip) or OCN (On-Chip Network) paradigm, a replacement...
A DRM system based on P2P whose certificate and digital production can both transmitted among users is presented to solve the bottle-neck problem of the usual system. We make the digital production transmitted quicker and the digital right of the production can be saved in security at the same time. The security proof of the system is given at the end of the paper.
We apply the concept of parameter identifiability to the security of parameters in chaos-based communication. The parameter is a good choice of the secret key if it is not identifiable. To test the parameter identifiability, we use the linear algebraic method based on differential 1-forms, which is applicable to more general systems than existing results. We analyze the identifiability of a chaotic...
By using of chaotic map and block-wise independent technology, a new chaotic fragile watermarking algorithm is proposed in this paper. Firstly, location key is looked as logistic chaotic initial value to iterate and create location matrix, according to this matrix we can generate mapping image and identify the embedding location of watermarking in image blocks. Then watermarking sequence related with...
