Abstract: A secure boot device, method, and system for securely connecting a client computer having a secure boot device to a remote server over a communications network are disclosed. The secure boot device includes a housing having an integrated communication interface, a controller located within the housing and operatively connected to the communication interface, and a memory communicatively connected to the programmable circuit and the communication interface. The memory securely stores program instructions including a boot module, a client terminal process module, an operating system module, and a secure communications interface module. The secure communications interface module includes program instructions for communicating split and encrypted data communicated between a computing system to which the communication interface is connected and a remote computing system.
