Abstract: A system includes a processor and a computer-readable medium storing instructions for execution. The instructions include generating a cryptographic pair of user public and private keys for a user. The instructions include registering an identity of the user with an identity provider, transmitting the user public key, and receiving a user certificate from the identity provider. The instructions include signing a trust certificate for a web server, including an address and a public key of the web server, with the user private key. The instructions include, in response to an access request from the user specifying a second web server: obtaining a second trust certificate from the second web server; and establishing a connection with the second web server in response to successful verification of a signature of the second trust certificate using a public key corresponding to a trusted contact of the user.
