The invention provides a downloading and mounting method of a signature authentication tool, and a terminal device. The method comprises the following steps: obtaining a downloading instruction of thesignature authentication tool; creating an auxiliary security domain in a built-in security element according to the downloading instruction of the signature authentication tool; establishing a security channel with a trusted service management platform, wherein the trusted management service platform is used for providing signature authentication tool downloading service; downloading, by the secure channel, a mounting file of the signature authentication tool into the built-in secure element; and mounting the signature authentication tool in the auxiliary security domain. By adoption of thescheme of the invention, the problem that a user cannot perform online transaction and registration at any time or the registration is troublesome is solved.
Description
technical field [0001] The present application relates to the technical field of information security, in particular to a method for downloading and installing a data signature tool and a terminal device. Background technique [0002] The signature authentication tool is a tool used for electronic signatures in online banking. It uses asymmetric key algorithms to encrypt, decrypt and digitally sign online transaction data to ensure the confidentiality, authenticity, integrity and non-repudiation of online transactions. [0003] In some current methods, the signature verification tool is usually installed and stored in an external security hardware to ensure that key information is not read or copied. Terminal equipment for online transactions is connected to ensure the security of online transactions. The external security hardware installed and stored with signature authentication tools is usually called U-shield, K treasure, USB-key, and so on. Although these external se...
