Abstract

The invention discloses a signing method of PKCS#11 interface calling cryptographic equipment. The method includes: when data signing needs to be performed on first data, in a packaged object set, using an object searching initialization function to search for a first object aiming at first data signing; using the object searching function to search for the object handle of the first object; using a signing initialization function to perform signing initialization by the aid of the object handle of the first object to obtain a first signing initialization result; using a signing function to sign the first data according to the first signing initialization result. By the signing method, data signing of the PKCS#11 interface calling cryptographic equipment can be achieved, data safety is enhanced, secret keys are not exposed outside the cryptographic equipment, and secrete key safety is increased. The invention further provides a signing device of the PKCS#11 interface calling cryptographic equipment, and the signing device has the corresponding technical effects.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a signature method and device for invoking a cryptographic device by a PKCS#11 interface. Background technique [0002] With the rapid development of computer technology, more and more attention is paid to information security. In order to enhance data security, it is often necessary to sign the data through a cryptographic device. When using a cryptographic device, the key pair is stored inside the cryptographic device and cannot be exported. [0003] At present, the most frequently used cryptographic algorithm interface in the world is the PKCS#11 interface. The full name of PKCS is Public-keyCryptography Standards, which is the standard of public-key cryptography. The PKCS#11 interface definition does not consider the use of hardware arithmetic operations. How to use the PKCS#11 interface to invoke a cryptographic device to perform data signature is a technical...
