Abstract

The invention discloses trusted wireless storage equipment for wireless power supply and an application method thereof, and relates to the field of secure information storage. A secure chip is a root of trust of the trusted wireless storage equipment and is a core module of the trusted wireless storage equipment. The invention points out information security problem in a wireless transmission process of the wireless storage equipment and provides a new trusted wireless storage solution for the wireless power supply. Each chip in the trusted wireless storage equipment for the wireless power supply is powered in turn according to a multi-stage power supply method, so that a system can quickly switch to a normal working state, and energy consumption is reduced to the greatest extent. Reliable power guarantee is provided for the trusted wireless storage equipment for the wireless power supply by various power supply methods. A trusted storage method guarantees confidentiality and completeness of data during interaction of the trusted wireless storage equipment for the wireless power supply and a computer and the confidentiality of the data during the interaction of the trusted wireless storage equipment and the storage equipment.

Description

technical field [0001] The invention relates to the field of information security, in particular to a trusted wireless storage device with wireless power supply and an application method thereof. Background technique [0002] trusted computing [0003] Trusted computing includes 5 key technical concepts, which are necessary for a complete trusted system, and this system will comply with the TCG (Trusted Computing Group) specification [0004] 1.Endorsement key endorsement key [0005] The endorsement key is a 2048-bit RSA public and private key pair, which is randomly generated when the chip leaves the factory and cannot be changed. This private key is always on the chip, and the public key is used to authenticate and encrypt sensitive data sent to the chip [0006] 2.Secure input and output [0007] Secure I / O refers to the protected paths between computer users and the software they think they are interacting with. Currently, malware on computer systems has many ways ...
