Traditional multi-step attack correlation approaches based on intrusion alerts face the challenge of recognizing attack scenarios because these approaches require complex pre-defined association rules as well as a high dependency on expert knowledge. Meanwhile, they barely consider the privacy issues. Under such circumstance, a novel algorithm is proposed to construct multi-step attack scenarios based on discovering attack behavior sequential patterns. It analyzes time sequential characteristics of attack behaviors and implements a support evaluation method. An optimized candidate attack sequence generation method is applied to solve the problem of pre-defined association rules complexity as well as expert knowledge dependency. An enhanced k-anonymity method is applied on this algorithm to realize privacy-preserving feature Experimental results indicate that the algorithm has comparatively better performance and accuracy on multi-step attack correlation and reaches a well balance between efficiency and privacy issues.

To efficiently implement the technology validation and test of power electronic devices, a new test method is presented, APF controller closed-loop simulation based on RTDS. Simulate those primary circuits by software in RTDS, such as three-phase grid, load and APF inverter bridge, DC side capacitor and circuit breaker. The APF control and protection part are done through the control panel in real devices. The standard interfaces of RTDS physical controller simulation are formed by 5 signal-conditioning modules, which fix the signal mismatch between APF controller and RTDS software models. In addition, construct the overall simulation model in RTDS small-step environment and some modeling methods of core modules are presented, including IGBT trigger pulse, protection and control signal logic, short circuit fault model in RTDS, operation observation interface and etc., which establish the complete test procedures and items. In the end, the effectiveness of the method is verified through comparative analysis of the test data between RTDS and real device testing. It brings up a new idea to efficiently implement the development and test of power electronic devices.

In this paper, an improved fruit fly optimization algorithm based on tournament selection mechanism (TS-FFO) is put forward. In TS-FFO, considering the fact that the aggregation way in the vision optimization phase will easily cause the loss of biodiversity and make the population jump into the local extreme, tournament selection mechanism is embed into FFO to randomly generate a new conductive individual to replace the current best fruit fly. In addition, in view of the blind search surrounding the best individual in the osphresis optimization phase, the evolutionary formula is also redefined by incorporating the current individual's own information to effectively control the evolution direction and step size. Six high dimensional benchmark functions are used to test and evaluate the TS-FFO. The experimental results demonstrate that TS-FFO has quicker optimizing efficiency and better accuracy compared with the standard FFO and several advanced algorithms. TS-FFO is also used to solve the image template matching problems and the statistical results show that our proposed approach is more effective and efficient than the particle swarm optimization (PSO) and differential search algorithms (DSA).

This paper analyzes the existing recursion formulas of SG-CMA, presents an improved SG-CMA with better convergence and stronger beam-forming gain. Considering the disadvantages of existing error functions, the algorithm makes some changes. It takes the sum of the signal modulus of each element as the expected value, which overcomes the fluctuation of signal modulus, and increases the application range and anti-noise capability. The signal modulus of an arbitrary array is built, then the SG-CMA and the improved SG-CMA are compared by simulation based on uniform linear array. The simulation results verify the effectiveness of the improved SG-CMA as well as its improvement on convergence and beam-forming gain.
