An online and offline circulating unbalanced oil and vinegar signature method

Abstract

The present invention discloses an online and offline circulating unbalanced oil and vinegar signature method, which decomposes the traditional unbalanced oil and vinegar signature process into offline and online parts, wherein the offline step is independent of the signature message, and can be performed in advance, and a combination of circulating calculation methods is used in the calculating process to improve performance. When the online part needs to be signed, the final signature operation is completed by using the calculated result stored in the offline step. The present invention is a multi-variable public key cryptosystem-based unbalanced oil and vinegar signature scheme, which is a lightweight digital signature scheme suitable for low-performance electronic devices. The invention decomposes the unbalanced oil and vinegar signature algorithm into offline and online parts, and the offline step calculation can be performed in advance, which can more fully utilize energy and accelerate the online signature process simultaneously. In the calculation of the offline step, the present invention uses a circulating calculation method, which greatly reduces the size of the secret key and shortens the signature period.
