Limited domain multiplication is the most basic computing in the elliptic curve cryptosystem(ECC), so it is very important to design fast time-multiplier to improve the speed of encryption and decryption. In this paper, Multiplication matrix was given on the analysis of the multiplication tables of optimal normal basis(ONB) in the finite fields, which can be used by type I and type II. The matrix...
Collection and analysis of information about network public opinion has currently become an effective means to get people thinking and recommendations by the government departments. In this paper, we presents a method of BBS(Bulletin Board System) hot topic analysis based on multiple keywords combination, this method, which use Chinese automatic word segmentation technology, firstly extracts keywords...
The number of cooperative sensors to use is a compromise between sensing performance and resources usage efficiency. The definition of the optimal cooperative sensor set is given out firstly and then a greedy selection algorithm for the optimal cooperative sensor set is proposed which can use fewest cooperative sensors to maximize the resources usage efficiency, while still having enough for the sensing...
Although the method of cooperative spectrum sensing can greatly improve the sensing performance, the consumption of system resources will increase as the number of cooperative sensors increases, therefore, the number of cooperative sensors to use is a compromise between sensing performance and consumption of system resources. Firstly, based on the expression for the probability of detection, a sensor...
The new dynamic spectrum environment in cognitive radio networks necessities novel routing protocols which should be spectrum-aware, self-configured, high-adaptive and robust to match the dynamic nature of Cognitive Radio Networks (CRN) and exploit the available spectrum efficiently. In this paper, we present ASAR, which is a biologically inspired routing solution for CRN. In our routing algorithm,...
This paper discusses teaching reform ideas in the ldquoscientific computingrdquo education by means of modeling and simulation, that can make students get a better understanding of the background, concept and design of each numerical algorithm in ldquoscientific computingrdquo education, and it will help them enhance their self-learning ability and exploration ability.
