Description

technical field [0001] The invention relates to the technical field of encrypted communication in integrated circuits, in particular to a fast encryption system for encrypting and decrypting data inside a chip, signing and verifying data. Background technique [0002] In the past ten years, with the rapid development of information technology, the popularity of computer networks and mobile terminals has greatly increased, and the amount of information transmission has increased suddenly. It contains a large amount of important military, political, economic, and personal information. If it is eavesdropped, tampered, intercepted, or destroyed during the dissemination and sharing of information, it will cause immeasurable losses. Therefore, the issue of information security has become an increasingly important subject, and people have put forward higher requirements for information security. Cryptography technology is an important part of solving information security problems,...

Problems solved by technology

However, the common elliptic curve encryption algorithm requires multiple operation modules (modular addition and subtraction, modular inversion, modular multiplication, point addition, point doubling, scalar multiplication, and protocol layer), and its computational complexity is relatively high. Processing, the ordinary elliptic curve encryption system will consume huge computing time and computing resources, resulting in particularly serious delays in data source encryption and decryption and signature verification, which greatly limits the application scenarios of elliptic curve encryption algorithms, and even endangers the encryption system. Timing environment, resulting in a series of design problems such as internal dysfunction of the encryption chip
