Abstract
A trusted computing device and an operating method thereof are provided. Provided is a trusted computing device including, a device driven by firmware, and a master controller generating an authentication value from the firmware and checking integrity for the authentication value at a first period, wherein the master controller includes, an authentication value generator generating the authentication value, an authentication value repository storing the authentication value, a security core blocking access from the outside with respect to the authentication value stored in the authentication value repository, and an integrity checker checking integrity for the authentication value stored in the authentication value repository.
Claims20
A trusted computing device, comprising:
- a device driven by firmware;
- and
- a master controller, which generates an authentication value from the firmware and checks integrity for the authentication value at a first period,
- wherein the master controller includes:
- an authentication value generator, which generates the authentication value;
- an authentication value repository, which stores the authentication value;
- a security core, which blocks access from the outside with respect to the authentication value stored in the authentication value repository;
- and
- an integrity checker, which checks integrity for the authentication value stored in the authentication value repository.
A trusted computing device, comprising:
- a first device, which is driven by first firmware;
- a second device, which is driven by second firmware;
- and
- a master controller, which generates a first authentication value from the first firmware to check integrity for the first authentication value at a first period, and generates a second authentication value from the second firmware to check integrity for the second authentication value at a second period,
- wherein the master controller includes:
- an authentication value generator, which generates the first authentication value and the second authentication value;
- an authentication value repository, which stores the first authentication value and the second authentication value;
- a security core, which blocks access from the outside with respect to the first and second authentication values stored in the authentication value repository;
- and
- an integrity checker, which checks integrity for the first and second authentication values stored in the authentication value repository.
A trusted computing device, comprising:
- a master controller that checks integrity for an authentication value of firmware that drives a device, wherein:
- the master controller checks integrity for the authentication value every first period,
- the master controller generates the authentication value through an authentication value generator,
- the master controller stores the authentication value through an authentication value repository,
- the master controller blocks access from the outside with respect to the authentication value stored in the authentication value repository, through a security core, and
- the master controller checks integrity for the authentication value stored in the authentication value repository, through an integrity checker.
