Publication number: 20240039714Abstract: Techniques are disclosed relating to relating to a public key infrastructure (PKI). In one embodiment, an integrated circuit is disclosed that includes at least one processor and a secure circuit isolated from access by the processor except through a mailbox mechanism. The secure circuit is configured to generate a key pair having a public key and a private key, and to issue, to a certificate authority (CA), a certificate signing request (CSR) for a certificate corresponding to the key pair. In some embodiments, the secure circuit may be configured to receive, via the mailbox mechanism, a first request from an application executing on the processor to issue a certificate to the application. The secure circuit may also be configured to perform, in response to a second request, a cryptographic operation using a public key circuit included in the secure circuit.Type: ApplicationFiled: August 9, 2023Publication date: February 1, 2024Inventors: Wade Benson, Libor Sykora, Vratislav Kuzela, Michael Brouwer, Andrew R. Whalley, Jerrold V. Hauck, David Finkelstein, Thomas Mensch

Patent number: 8954740Abstract: A server receives identifying information of a user of a client device and data encrypted with a public key of a group, where the encrypted data includes an encrypted session key for secure content. The server determines whether the user is a member of the group using the identifying information of the user. If the user is a member of the group, the server decrypts the encrypted session key using a private key of the group, and causes the client device to obtain a session key to access the secure content.Type: GrantFiled: October 4, 2010Date of Patent: February 10, 2015Assignee: Symantec CorporationInventors: Vincent E.
