Post-quantum cryptography has become a research hotspot in the current security field.In this paper,a secure SoC design scheme based on post-NIST quantum cryptography is proposed by studying Saber algorithm,which is a candidate of post-NIST quantum cryptography competition.The scheme firstly analyzes the hardware architecture of the algorithm,optimizes operations such as matrix operation and numerical splicing to improve hardware efficiency,and uses secondary verification to enhance the security of the decryption process of the algorithm,design Hash random number expansion generation module,encryption and decryption module and data storage and random number seed generator to complete the Saber algorithm hardware IP Core.On the basis of RISC-V processor,bus and in-terface circuit,a secure SoC based on post-quantum cryptography is designed with clock gating technology.The experimental results demonstrate that the area of the designed security SoC chip is 2.6 mm2,with an equivalent logic gate count of 90k.The chip core area accounts for 75.2％,the PAD area accounts for 24.8％,and the chip power consumption is 9.467 mW.
