Description

Technical Field

[0001] The utility model relates to the technical field of information security and defense computer engineering applications, and particularly relates to an authentication carrier applicable to harsh environments and a tabletop mounting adapter thereof. Background Art

[0002] Identity authentication refers to the process of a computer and network system confirming the identity of an operator, mainly solving the important problem of corresponding the physical identity of the operator with the digital identity. This technology has been widely applied in many fields with high requirements for information security, such as online banking, securities, industrial and commercial taxation, e-commerce, etc. By authenticating the identity of personnel operations, information and fund security can be guaranteed.

[0003] The USB Key (authentication carrier) combines modern cryptography technology, smart card technology, and USB technology, and is used as the carrier of digital certificates and private keys for user identity authentication and electronic signature. It is a general identity authentication product at the present stage, with characteristics such as a secure storage space, small size, light weight, and easy portability. The identity authentication method of the USB Key (authentication carrier) is a convenient, secure, and reliable identity authentication technology, and is a relatively mainstream authentication method in the commercial field at the present stage.
