Description

technical field [0001] The invention relates to the security field of encryption equipment, in particular to a general encryption equipment power consumption capture system for various encryption chips. Background technique [0002] Today, the functionality and importance of encrypted devices is accepted for many applications. Since the hardware carrier of the encryption algorithm has higher security and efficiency than the software form, it has been designated as an essential security protection platform and encryption form by many industries. The hardware carrier includes cryptographic chips, smart cards, etc. [0003] Traditionally, the security of an encryption device is determined by the cryptographic algorithm used, the authentication method, and the mathematical complexity of the security protocol. However, for a practical encryption device, its security is not only related to the cryptographic algorithm used, but also involves program implementation and hardware de...

AI Technical Summary

Problems solved by technology

The existing power consumption capture methods mostly use oscilloscopes and other equipment for linkage acquisition. There are several problems in the actual power consumption test: First, for different types of encryption equipment, even for different products of the same type of encryption equipment, it is difficult to collect power consumption. Large, low versatility; Second, high-frequency sampling oscilloscopes are expensive, which greatly increases the cost of testing
