Design and implementation of system-on-chip for peripheral component interconnect express encryption card based on multiple algorithms

Abstract

Purpose The data protection is always a vital problem in the network era. High-speed cryptographic chip is an important part to ensure data security in information interaction. This paper aims to provide a new peripheral component interconnect express (PCIe) encryption card solution with high performance, high integration and low cost. Design/methodology/approach This work proposes a System on Chip architecture scheme of high-speed cryptographic chip for PCIe encryption card. It integrated CPU, direct memory access, the national and international cipher algorithm (data encryption standard/3 data encryption standard, Rivest–Shamir–Adleman, HASH, SM1, SM2, SM3, SM4, SM7), PCIe and other communication interfaces with advanced extensible interface-advanced high-performance bus three-level bus architecture. Findings This paper presents a high-speed cryptographic chip that integrates several high-speed parallel processing algorithm units. The test results of post-silicon sample shows that the high-speed cryptographic chip can achieve Gbps-level speed. That means only one single chip can fully meet the requirements of cryptographic operation performance for most cryptographic applications. Practical implications The typical application in this work is PCIe encryption card. Besides server’s applications, it can also be applied in terminal products such as high-definition video encryption, security gateway, secure routing, cloud terminal devices and industrial real-time monitoring system, which require high performance on data encryption. Social implications It can be well applied on many other fields such as power, banking, insurance, transportation and e-commerce. Originality/value Compared with the current strategy of high-speed encryption card, which mostly uses hardware field-programmable gate arrays or several low-speed algorithm chips through parallel processing in one printed circuit board, this work has provided a new PCIe encryption card solution with high performance, high integration and low cost only in one chip.

Construction of power network security risk assessment model based on LSA-SVM algorithm in the background of smart grid

“…Aiming at the problem of high training cost of traditional PS security assessment model, Thams et al proposed an improved and highly scalable algorithm based on complex network theory, and empirically analysed the algorithm, and found that the algorithm's training cost is much lower, and its training time is 10% of that of the traditional algorithm, which is of practical application value 15 . In order to protect PN data security, Chen et al proposed an improved encryption system architecture based on high-speed encryption chip, and empirically tested the scheme, and found that the scheme can meet the performance of most cryptographic operations, with a certain degree of ubiquity, and has the potential for practical application 16 . In order to conduct real-time analysis of complex PS and respond to emergencies, Silva et al proposed and risk response only system based on static security analysis, and empirical analysis of the system found that the system can cut off emergencies, and its response accuracy rate is close to 59%, which is of practical use value 17 .…”

Research on Computer Network Security Vulnerabilities and Encryption Technology in Cloud Computing Environment

“…Today's current stage of information technology and computer networks has been able to develop rapidly, and at the same time, it has had a certain impact on contemporary society and, even to a certain extent, has changed the whole world. However, in the whole development process, people should pay attention to the sensitivity and specificity of data and information issues, and at the same time, strengthen the information encryption and protection of the importance of information, and can effectively promote the current computer network communication security [9][10][11][12].…”
