In order to promote the feasibility of the construction of cubic splines, this paper presented a novel pseudoinverse-based construction method (PCM) to construct the cubic spline function effectively. Without using endpoint-constraint conditions, this method obtained the solution of the second-order derivatives of the cubic spline that was closest to the origin, namely the minimum norm solution. Theoretical analysis and numerical experiments highlight the efficacy of the PCM. For better understanding, it further studied and investigated the characteristics of various construction methods. In this way, it provided guidelines for choosing suitable methods to construct cubic splines in practical applications of engineering calculation. [ABSTRACT FROM AUTHOR]

The ranges of state variable value of transition system are large, and the state space of system transition, but the transitions of the system are often unpredictable. This paper defined the concepts: initial safety states, safety transition condition, safety state, safety action, safety run and safety transition system, and proved the all states in safety transition system were safe. Then it used it to remold the network transition system, and changed it a safety transition system. [ABSTRACT FROM AUTHOR]

This paper proposed a multi-authority attributed based signature scheme based on distributed ABE, which was suitable for distributed system. It compared with traditional schemes, our scheme allowed an arbitrary number of authorities to independently maintain attributes and distribute secret attribute keys. The master authority was responsible for the distribution of secret user keys, without need to supervise each attribute authority. Attribute authorities were responsible to verify whether a user is eligible of a specific attribute, and every attribute is associated with a single attribute authority. Our construction was very efficient, as it required only a small amount of pairing operations during sign and verification. Our scheme has a good flexibility, and has a great of practical value in practical applications. [ABSTRACT FROM AUTHOR]

To detect malware such as bot and trojan, this paper proposed a method based on inherent activities of compromised hosts. This method identified suspicious network traffic through persistent arithmetic that measured if hosts had temporal regularity when communicating with other hosts, and analyzed suspicious network traffic through rules of user driven activities and occurring moments to detect compromised hosts. The results show that the system can accurately detect compromised hosts with low error rates. [ABSTRACT FROM AUTHOR]

Through the cryptanalysis of a certificateless proxy blind signature scheme proposed by Ge Rong-liang, it find that this scheme can cause the public replacement attack and malicious-but-passive KGC attack. To avoid these attacks, this paper proposed a new improved scheme. Analysis result shows that the new improved scheme satisfies the requirements of proxy blind signature scheme and has the same computational efficiency compared with the original scheme.
