Abstract: This application relates to an inter-application communication method and apparatus, a storage medium, and a program product. The method is used in an electronic device. The electronic device runs a first virtual apparatus and a second virtual apparatus, one of the first virtual apparatus and the second virtual apparatus is a virtual machine, and the other is a physical machine. The method includes: the first virtual apparatus writes a first command into a first command queue based on a first request sent by a first application. The first virtual apparatus outputs a first inter-core interrupt to a core in which the second virtual apparatus is located. The second virtual apparatus obtains the first command from the first command queue based on the first inter-core interrupt. The second virtual apparatus runs a second application based on an identifier that is of the second application and that is in the first command.

Abstract: This application provides a method for secure multi-terminal cooperative working, applied to a network on which a plurality of terminal devices perform cooperative playing and/or cooperative recording, where the plurality of terminal devices include a first terminal device. The method includes: determining, by the first terminal device, a security mechanism; obtaining, by the first terminal device, cooperative working information, where the cooperative working information is information played and/or recorded by the plurality of terminal devices; and performing, by the first terminal device, security processing on the cooperative working information based on the security mechanism. After obtaining the cooperative working information, the first terminal device performs security processing on the cooperative working information based on the security mechanism, so that a process other than the cooperative working process cannot access the cooperative working information, thereby ensuring security of the cooperative working information.

Abstract: Various embodiment provide a multi-terminal cooperative working method, a terminal device, and a multi-terminal cooperative system. In those embodiments, a primary device can send networking information to a plurality of secondary devices, and the primary device has a permission to manage the cooperative network. The primary device can receive networking confirmation information sent by the plurality of secondary devices; and send configuration information to the plurality of secondary devices separately. The configuration information can be used to instruct to switch, based on a preset management permission switching mechanism when the primary device becomes abnormal or the primary device exits from the cooperative network, the permission to manage the cooperative network. The primary device can clear the secondary device from the cooperative network the secondary device becomes abnormal. In this way, robustness of the cooperative network can be improved.
