The invention discloses a method for controlling a single board to be safely started. The method comprises the steps that after the single board is powered on, the resigned name of a software package to be loaded to the single board is acquired, the resigned name of the software package is obtained by using a single plate private key of the single board for resigning the software package, and is made after the original signature of the software package passes verification through a software package public key of the software package, and the original signature is obtained by signing the software package through a software package private key of the software package; the resigned name of the software package is verified through a single board public key paired with the single board private key; after the resigned name passes verification, the single board is started. According to the method for controlling the single board to be safely started, it can be guaranteed that the single board can still be safely started when the private key of the software package is leaked.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for controlling the safe startup of a single board. Background technique [0002] As the threat of hackers increases, operators have put forward requirements for a trusted environment for telecom equipment. For example, when starting a multi-mode base station, the software must be verified by cryptographic means. If the verification fails, the multimode base station cannot access the network. [0003] Manufacturers of telecommunications equipment usually generate an asymmetric key pair in advance. As the manufacturer's key, the equipment manufacturer will properly keep the private key in the key pair, and use the private key to sign the software package to be released. The key pair The public key in is distributed with the package. [0004] When the single board in the telecommunication equipment is safely started, it is necessary to verify the softwa...
