  • Publication number: 20120137128
    Abstract: Systems and methods for securing a credential generated by or stored in an authentication token during an attempt to access a service, application, or resource are provided. A secure processor receives a credential from an authentication token and securely stores the credential. The secure processor then verifies the identity of the individual attempting to use the authentication token and cryptographically verifies the identity of the server being accessed. The credential is only released for transmission to the server if both the identity of the individual and the identity of the server are successfully verified. Alternatively, a secure connection is established between the secure processor and the server being accessed and a secure connection is established between the secure processor and a computing device. The establishment of the secure connections verifies the identity of the server. After the secure connections are established, the identity of the user is verified.

  • Patent number: 8086844
    Abstract: An online trusted platform module (TPM) in communication with a security module that can be located elsewhere in the network in a server machine. In an embodiment, the online TPM is connected directly to a network interface card (NIC) that is also resident at the client. This allows the online TPM to communicate directly to the network, and therefore to the security module (without having to deal with the TCP/IP stack at the client machine in some circumstances, e.g., the boot process). In an embodiment, the communications channel between the online TPM and the security module is implemented using the transport layer security (TLS) protocol. A secure boot process is performed in advance of security processing. Typical security processing includes receipt, by the online TPM, of one or more commands from an application. The online TPM then proxies out the commands to the security module.
