Abstract

The invention provides an update method, an update system and a security authentication device. After the security authentication device receives an update command, the device generates a certificate request by using a certificate renewal key preset in the security authentication device. After that, the device applies a certificate to a security authentication server by using the certificate request. Since the certificate request is generated based on the certificate renewal key preset in the security authentication device, the certificate request is encrypted in the security authentication device. Meanwhile, the security authentication device itself is capable of resisting attacks and avoiding the key leakage, so that the certificate request grenade by the security authentication device is higher in security. Therefore, the risk that the certificate request is tampered is lowered. As a result, the security of the update process is improved.

Description

technical field [0001] The present application relates to the field of electronic information, in particular to an updating method and system, and security authentication equipment. Background technique [0002] With the increasing number of online banking users, the validity period of the certificates issued by banks for security authentication devices (such as online banking shields) is generally 3 or 5 years. When the customer's security authentication device certificate expires or is about to expire, the user usually needs to connect to the bank's online banking system to complete the certificate update before using the security authentication device normally. [0003] During the update process, even if the certificate request generated by the client (referred to as P10) is illegally tampered with, for example, the public-private key used to generate P10 information is known to the attacker, the online banking server is not aware of it, so the online banking server is st...
