Software security verification method, equipment and system

The present invention relates to the field of communications. Disclosed are a software security verification method, equipment and system, capable of solving the problems of increment of VNF instantiation time delay and reduction of VNF instantiation performance if security verification is carried out on a VNF package in the prior art. The specific solution is as follows: after a first device receives an instantiation request of a VNF, the first device performs, according to the instantiation request of the VNF, security verification on the stored VNF package about the VNF at the time when the VNF is begun to be instantiated or after the VNF is begun to be instantiated; and when the security verification on the VNF package about the VNF succeeds, the first device sends first result information to a second device, the first result information comprising security verification success information about the VNF package about the VNF. The present invention is used for software security verification.
