The invention discloses a method for controlling the safe startup of a single board, comprising: after the single board is powered on, obtaining the re-signature of the software package to be loaded into the single board, and the re-signature of the software package is to use the single board The board private key of the board re-signs the software package, and the re-signature is made after the original signature of the software package is verified by using the software package public key of the software package. The original signature is obtained by signing the software package using the software package private key of the software package; using the board public key paired with the board private key to verify the re-signature of the software package; After the re-signature passes the verification, start the single board. The method for controlling secure startup of a single board provided by the embodiment of the present invention can ensure that other single boards can still be safely started when the key pair 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...
