Title: SIGNATURE VERIFICATION METHOD, DEVICE AND SYSTEM
Abstract:
Embodiments of the present application provide are a signature verification method, device and system. The method comprises: according a private key and a digital signature algorithm, a sending side determines a signature of a message to be sent; a host verifies the message and the signature according to a public key and the digital signature algorithm; when the public key corresponds to the private key, the host determines a check code of the message according to a preset key, the complexity of an algorithm used by the check code being lower than that of the digital signature algorithm, and the host and the sending side having a capability of a digital signature; and a receiving side verifies the message according to the check code and obtains the message, the receiving side being an embedded system. In the embodiments of the present application, the host computer performs the digital signature algorithm instead of a reception side, so that the reception side does not need to use a high-complexity digital signature algorithm to verify data; accordingly, by means of the embodiments of the present application, the authenticity and the integrity of the data received by the reception side of low hardware costs can be ensured.
