An application program control method based on a two-time signature verification technology is achieved by performing two times of signing and two times of signature verification on application programs on an android terminal. Security detection is performed on the application programs through a reliable third-party security detection mechanism, the application programs passing the detection will be signed by the third-party security detection mechanism, and then the signed applications are returned to developers. When the application programs are installed on the intelligent android terminal, security detection is performed on the application programs first to see whether the application programs are signed by the third-party security detection mechanism or not, and signatures are verified; if signatures of the third-party detection mechanism do not exist or the signatures cannot pass verification, installation of the application programs is refused. Through the technical scheme, the application program control method based on the two-time signature verification technology has the advantages that signature information is fixed through introduction of the third-party detection signatures and a security control module of the android terminal so that secure application programs can be downloaded and installed in an android system through multiple channels, and while security of the android terminal is guaranteed, a flexible and efficient application program verification scheme is provided.

The invention discloses a security service chain dynamic arrangement device, and relates to the technical field of network security. The device comprises a flow classification module, a security function virtual machine management module, a lightweight virtual security resource management platform, a network management module and a flow table generation module. The flow classification module is used for generating a flow classification result flow table; the security function virtual machine management module performs management operation on the security function virtual machine; the lightweight virtual security resource management platform realizes operations of creating, starting, deleting and the like of the security function virtual machine; the network management module realizes network configuration of the security function virtual machine; the flow table generation module is used for generating a flow traction flow table. According to the invention, through a security function service chain mode, differentiated security protection capabilities can be provided for different flows according to security requirements and network states, fine-grained, definable and diversified security protection ways are provided for the network. The method has the broad application prospect.
