Hybrid traffic security shaping scheme combining TAS and CQSF of time-sensitive networks in smart grid

The new intelligent factory introduces Time-Sensitive Network into industrial Ethernet to provide real time and deterministic guarantee communication for production system. Since the problem pertaining to data leakage or damage during transmission has increasingly become pronounced, security protection technology has been introduced, but this technology will bring about a delay in user response and a decline in the quality of service. Meanwhile, ensuring the deterministic mixed transmission of time-sensitive and large-bandwidth data traffic supported by the same switching device is a still challenging problem. Therefore, this study proposes a hybrid security scheduling scheme which combines Time-Aware Shaper and cycle specified queuing and forwarding (CSQF). Specifically, the mechanism first adopts various encryption methods for different traffic, and afterward, it reduces its resource occupation by adjusting the sampling period of the time-sensitive traffic. At the same time, it adopts CSQF to schedule the large-bandwidth data traffic, thereby improving the scheduling success rate. According to the experimental results, this scheme enhances network security and network scheduling success rate by up to 51%. The scheduling of mixed traffic in the Time-sensitive Network is realized securely and efficiently.

A robust and lossless commutative encryption and watermarking algorithm for vector geographic data

As an organic integration of encryption and watermarking technology, commutative encryption and watermarking (CEW) overcomes the limitation that a single security protection technology cannot provide full-process data protection. Existing CEW algorithms for vector geographic data, however, only take attack robustness into account, making them inappropriate for copyright protection of high-precision vector geographic data since the influence of embedding watermark on data accuracy. This study presents a CEW algorithm that utilizes geometric features and the initial vertex order of features to address this issue. The minimum bounding rectangle (MBR) is chosen as the geometric characteristic in this method to provide independent operating space for watermark and encryption. The encryption is completed by randomly shifting the coordinates of the features. At the same time, the watermark information is embedded by modifying the features' starting vertex order. The watermark can be extracted either from the plaintext or the ciphertext, as the order of the element's starting points remains unchanged regardless of the coordinates. Finally, the commutative, robustness, and lossless ness of the algorithm in this study are experimentally validated. As can be demonstrated by the results, the proposed algorithm is more robust, lossless, and secure than some state-of-the-art algorithms.

Research on computer network security protection technology based on a superiority algorithm

Abstract The rapid development of computer network technology has brought great convenience to all walks of life and made the transmission of various information faster. A secure and reliable computer network environment has a critical impact on the functioning of the computer network. In this paper, we derive and analyze the detection probability, false alarm probability and judgment threshold of the new algorithm based on the results of random matrix theory based on the feature-fitting superiority algorithm, which can exhibit better detection performance. In the framework of matrix theory, the superiority algorithm reduces the problem of network security to some extent and improves the performance relative to other fitted superiority detection algorithms. For common threats to network security, give the corresponding ideas to deal with network security issues from a technical perspective. The detection rate and false alarm rate are calculated by testing the total number, the number of intrusion bars, the number of detected intrusion bars, and the number of false alarm bars detected by the system, respectively. The test results show that the average detection rate is still greater than 94%, the average false alarm rate has improved, and the average false alarm rate is controlled at about 3.1%, which can fully meet the system requirements. Give reference to further enhance the reliability and stability of network security systems.
