Methods and systems for updating a secure boot device using cryptographically secured communications across unsecured networks

A system for updating one or more trusted software modules in a secure boot device directly connected to a client computing system, the system comprising:

• a service enclave configured to receive and respond to authentication and authorization requests from a client computing system, and to define one or more communities of interest associated with a secure boot device;
• a customer enclave configured to, upon authorization of the secure boot device at the service enclave, establish a secure connection to the client computing system and receive transaction information from the client computing system;
• and
• an update enclave configured to, while the secure connection is established between the customer enclave and the client computing device, establish a second secure connection between the update enclave and the client computing device and update one or more of the trusted software modules.

A computer-storage medium storing computing instructions which, when executed, implement a computerized method of updating a virtual terminal associated with a secure network, the method comprising:

• validating at a service enclave an identity of a user of a virtual terminal, the service enclave including an authorization server, and the virtual terminal generated from a trusted set of processing modules executing from a secure boot device at a client computing device;
• authorizing the user of the virtual terminal to access a customer enclave based on security credentials received from the virtual terminal;
• and
• while the user of the virtual terminal establishes a secure connection between the client computing device and the customer enclave, transmitting updates from an update enclave to the client computing device, thereby updating the trusted set of processing modules.
