Problems solved by technology

[0002] At present, the known USB Key is a digital certificate key storage carrier based on the PKI (Public Key Cryptography Infrastructure) system, and it is also a cryptographic device that completes digital certificate encryption / signature, but it can only ensure that data information is encrypted / signed by the digital certificate in the Key. The security after signature output cannot guarantee the security of data information input from untrusted network devices (computers, PDAs, etc.) to USB Key, when untrusted network devices (computers, PDAs, etc.) There is no way for users to find out and stop when the authentication and transaction information has been tampered with or has been tampered with
