Portable system and method for remotely accessing data

摘要

Embodiments of the present invention provide a portable system and method for accessing data remotely. The system and method include a first module and a second module, each of the modules being associated with the host system, wherein the first module is capable of being connected to the host system and the second module, and the second module is capable of being connected to the remote system to establish a secure communication channel between the first and second modules across the data link to access the data.

主权项

1. A portable system for accessing data stored on a host system from a remote system using a data link, the system comprising:
a first hardware device and a second hardware device; wherein said first hardware device is capable of being physically connected to both said host system and said second hardware device to associate said first hardware device, said second hardware device and said host system with each other by generating a random master cryptographic key that is stored on each of said first and second hardware devices, and by providing an address of the host system to said second hardware device; and
wherein said second hardware device is capable of being physically disconnected from said first hardware device and physically connected to said remote system to generate a session key from said master cryptographic key to establish a secure communication channel between said first and second hardware devices across said data link based on the obtained address of the host system to enable the remote system to access said data on the host system, wherein second hardware device and said host system are securely connected with each other using a unique identifier of the host system, and wherein said unique identifier of the host system is at least one identifier selected from a group consisting of a media access control address of said host system, a hard disk identification number of said host system, an internet protocol address of said host system, and a randomly generated pairing, identifier.
