[Abstract]:With the rapid development of the Internet of things, the security of restricted devices has been seriously challenged. As the main security measures of restricted devices, lightweight cryptography has attracted more and more researchers' attention. This paper reviews the design strategy, security and implementation performance of lightweight cryptography. This paper expounds the common design strategies and key problems in the design of lightweight ciphers, and analyzes and discusses the typical and common lightweight ciphers from the aspects of principle, realization mechanism and so on. This paper summarizes the common methods of lightweight cryptographic security analysis, and emphasizes the threat of bypass attack and the problems that should be paid attention to when adding protection mechanism. The existing lightweight cryptographic algorithms are compared and analyzed in detail from the point of view of various important indexes of lightweight cryptographic performance, and the applications of hardware-oriented and software-oriented lightweight ciphers are pointed out. Finally, some unsolved problems in the current lightweight cryptography research and the possible development direction in the future are pointed out. Combined with the characteristics of lightweight cryptography and its application environment, it is pointed out that the comprehensive evaluation of the security and implementation performance of lightweight ciphers is a problem worthy of further study in the future.
