into entering their usernames and passwords. SSL performs this authentication by using an SSL certificate provided by a trusted authority such as VeriSign. The logic is as follows: VeriSign guarantees that the identity of the Bank's website is true. Because Internet Explorer trusts VeriSign, it also trusts the website. If you want to verify with

To apply for a certificate with the name of VeriSign, the applicant must prove that he is a registered company and has the right to use a specific Internet domain name.

Unified user authentication is based on uums. It provides unified authentication methods and policies for all application systems to identify the legitimacy of user identities.

Ca is the authority responsible for issuing certificates, certification certificates, and managing issued certificates. It requires policies and specific steps to verify and identify user identities, and sign user certificates to ensure the identity andPublic Key. For example, Alice communicates with Bob.
