He HMAC algorithm involves a hash function with a secret key. And SM3 is the only standard hash algorithm of China. HMAC-SM3 algorithm is based on the mixing of different algebraic operations, such as XOR and addition modulo 232, thus the classical side-channel attacks on it are mainly against these basic group operations and need to exploit multiple leakage models. Therefore, the attack procedures...
Driving fatigue detection is an important approach to ensure the traffic safety. However, the most existing mature analysis methods are based on driving behavior or driver's body characteristics, which leads to the low accuracy and predictability. The EEG signal analysis is proved to an effective way to reflect the fatigue state in medical science, thus this paper explores the EEG signal to detect...
The study analyzes the dosimetric variation due to the misalignment of the device under test (DUT) during numerically evaluation of specific absorption rate (SAR). The novelty of the research is to discuss the individual effect of the six misalignment directions to the SAR variation. In this work, five DUT models are generated. Finite-difference time-domain method is applied according to the specification...
With the development of information technology, electronic handbook is used commonly. The important of electronic handbook materials is growing, so that a model of word resource management system based on Open XML is submitted in order to realize materials' collection and sharing. And introduce the application of Open XML in Word resource management system.
In the background of coal mine production safety accidents happening frequently in our country, the establishment of safety evaluation system is to be imperative in coal mine on the basis of the concept of sustainable development. In this paper it established a set of safety management system which is self restraint, collaborative operation and effective, according to its five internal system of coal...
China has implemented the oil and gas industry reforms in 1998, but there is few quantitative analysis on the performance of deregulation reform. We construct two econometric models - the profit model and the efficiency model, select 1986–2008 years data as a sample, use co-integration analysis including the structural breaks, we shows that deregulation dummy variables have a significant impact for...
In the research of Emergency Preparedness (EP), knowledge representation and storage of the EP is one of the most important tasks. However, most of the existing plans are ill-structured and lacked compatibility, which makes it difficult to manage. In this paper, we proposed a formal description of their features and contents, which conforms to Open XML standards, on the basis of the analysis of EPs...
