COMPUTING DEVICE IN A TRUSTED COMPUTING SYSTEM AND ATTESTATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17859263 titled 'COMPUTING DEVICE IN A TRUSTED COMPUTING SYSTEM AND ATTESTATION METHOD THEREOF
Simplified Explanation
The abstract describes a computing device and a method for attestation in a trusted computing system. The device includes a processor that can transmit identification information and a nonce to a master controller. The processor also performs attestation for multiple devices based on an aggregated signature.
- The computing device is part of a trusted computing system.
- The device includes a processor that can transmit identification information and a nonce to a master controller.
- The processor performs attestation for multiple devices based on an aggregated signature.
- The aggregated signature is generated by using a nonce and signatures from the devices.
Potential Applications
- Trusted computing systems
- Secure communication protocols
- Authentication and verification processes
Problems Solved
- Ensuring the trustworthiness of devices in a computing system
- Verifying the identity and integrity of devices in a trusted computing system
- Preventing unauthorized access and tampering in a computing system
Benefits
- Enhanced security and trust in computing systems
- Efficient attestation process for multiple devices
- Protection against unauthorized access and tampering
Original Abstract Submitted
A computing device in a trusted computing (TC) system and an attestation method thereof are provided. The computing device includes at least one processor configured to operate as instructed by program code, the program code including: transmission code configured to cause the at least one processor to transmit, to a master controller, a first identification (ID) for a first device selected among a plurality of devices included in the TC system, a second ID for a second device selected among the plurality of devices, and a nonce; and attestation code configured to cause the at least one processor to perform attestation for the first device and the second device based on an aggregated signature, wherein the aggregated signature is based on generation of a first signature, by the first device, by using the nonce, and generation of a second signature, by the second device, by using the first signature.
