Title:
SIGNATURE VERIFICATION METHOD PERFORMED IN COMPUTING DEVICE AND COMPUTING DEVICE FOR PERFORMING SAME
Document Type and Number:
WIPO Patent Application WO/2024/090659
Kind Code:
A1
Abstract:
The present invention relates to a method for verifying a signature during transmission and reception of a message between computing devices. The signature verification method performed in a computing device, according to the present invention, comprises the steps of: receiving a signature, generated by encrypting, with a private key, a message to be signed, and the message; performing a point operation on a public key, generated as a point on a first coordinate system defined as a finite field from the private key, on the basis of coefficients obtained from the signature and the message; and verifying the signature by comparing the result of the point operation with the signature. In the step of performing the point operation, it is preferable to perform an operation by referring to the result of a point operation according on the obtained coefficients, or a value in an operation table in which at least some of sub-operations constituting the point operation are prestored. According to the present invention, accurate information can be provided due to an improved verification speed even during high-speed traveling. In addition, the present invention enables more stable transmission/reception of information through parameters optimized depending on self-driving conditions.
