Specifically, the device information may include a terminal IP Address, a MAC Address (Media Access Control Address), and the like.
Specifically, before the current terminal sends the device information to the server, the user identity of the current terminal may also be verified. For example, the identity certificate is obtained through a pre-configured login interface, the identity certificate input by the user is matched with the authenticated identity certificate stored locally, and if the matching is successful, the identity of the user is confirmed to be verified; or the current terminal sends the identity certificate input by the user to the server so that the server matches the identity certificate with the authenticated identity certificate prestored in the server, and if the matching is successful, the user identity is confirmed to pass the verification. In particular, the identity credential may include a user account and an account key.
In some embodiments, the configuration information includes: the security domain configuration information comprises a plurality of security domain configuration information and encryption keys corresponding to the plurality of security domain configuration information.
In the embodiment of the present application, the security domain configuration information is used to characterize the security domain to which the created container belongs and its related information. In particular, the information relating to the security domain typically includes a range of IP addresses within the security domain.
In this embodiment of the present application, the encryption key is used to encrypt the virtual disk created for the container, so as to obtain a virtual encrypted disk.
In an embodiment including step S1022, as shown in fig. 1, the step of step S1022 further includes:

Specifically, the container information corresponding to any secure container generally includes an IP address of the current terminal, a container identifier, a container name, and other information uniquely characterizing the container. The container identifier may be represented in the form of a serial number, a document tag, or the like.
Specifically, when the current terminal sends a communication request to the server, the communication channel allocated to the current terminal may be encrypted by using the encryption key corresponding to the security domain configuration information, so as to achieve an effect of encrypting the communication channel.
In the embodiment of the application, the virtual network card is used for acquiring the allocated virtual IP address from the virtual IP address allocation server, so as to implement mutual communication between different security containers.
Specifically, when the security domain configuration information generally includes an IP address range of the terminal, the current terminal may send the security domain configuration information to the virtual IP address allocation server, so that the virtual IP address allocation server allocates virtual IP addresses to the multiple security containers in the current terminal according to the IP address range, so that the virtual IP addresses acquired by the multiple security domain containers respectively conform to the IP address range of the security domain to which the virtual IP addresses belong, and the security container is accessed to the local area network of the security domain to which the virtual IP address range belongs.

When applied, the new container creation process can be performed in the current terminal with reference to this embodiment. Specifically, after determining the security domain configuration information selected by the user, the corresponding encryption key is also determined. After the virtual disk is created at the current terminal, encryption processing is carried out by using an encryption key corresponding to the security domain configuration information selected by the user, and a virtual encryption disk is obtained; calling a local command, creating a new container according to security domain configuration information selected by a user, and mounting a virtual encryption disk to the new container; and calling a local command to create a virtual network card for the new container, and acquiring a virtual IP address from the virtual IP address allocation server through the virtual network card. Specifically, the current terminal may send the security domain configuration information according to the new container to the virtual IP address allocation server, so that the virtual IP address allocation server allocates a virtual IP address to the virtual network card of the new container, and the virtual IP address acquired by the new container conforms to the IP address range of the security domain pointed by the security domain configuration information selected by the user.
In some embodiments, the communication control method as shown in fig. 1 further comprises:
step S106 (not shown in the figure): and determining a file storage path query table of each of the plurality of security containers according to the virtual encryption disk corresponding to each of the plurality of security containers, so as to perform file query according to the file storage path query table.
In an embodiment of the present application, the file storage path query is used to characterize respective storage paths of different files in the secure container. The file storage path lookup table provides a function of positioning files for a terminal user, and the time of querying the files in the virtual encrypted disk by the user is shortened.
In some embodiments, before step S105, the method further includes: step S1051 (not shown in the figure): matching the container information of the second safety container with the container information corresponding to the plurality of safety containers operated in the current terminal, and judging whether the second safety container operates in the current terminal according to a matching result; step S105 further includes: step S1052 (not shown in the figure): and if the second safety container does not operate in the current terminal, sending the communication request to the server.
Specifically, the container information of the second secure container is inquired in a container information table pre-stored in the current terminal, and the container information table comprises the container information corresponding to each of the plurality of secure containers operating in the current terminal, so that whether the second secure container operates in the current terminal can be determined through inquiry, and when the communication operation is the communication operation between the cross-terminal secure containers, the communication between the cross-terminal secure containers is processed through the server, and the purpose of controlling the communication range is achieved.
In some embodiments, before step S105, the method further includes: judging whether the second safety container operates at the current terminal or not according to the container information of the second safety container; step S105 further includes: if the second safety container runs at the current terminal, a communication control strategy is obtained from the server; determining a plurality of first container information sets according to the communication control strategy; and if the container information of the first safety container and the container information of the second safety container are in the same first container information set, sending the communication request to the second safety container.
Specifically, the current terminal sends a request for obtaining a communication control policy to the server, so as to obtain the communication control policy fed back by the server.
In an embodiment of the present application, the first container information set includes container information corresponding to each of a plurality of secure containers that allow communication.
Specifically, the communication control policy is generally set to: different secure containers within the same secure domain are allowed to communicate, i.e. the first set of container information comprises respective container information of all secure containers within the same secure domain. Through the setting of the first container information set, the communication range is controlled in the same security domain, the access of a terminal outside the security domain to data in the security domain is prevented, the data in the domain is prevented from being leaked, and the security of data access is improved.
For example, assuming that the container information includes container identifiers, if the container identifier of the first secure container and the container identifier of the second secure container are both located in the same first container information set, it may be determined that the first secure container and the second secure container belong to the same security domain, and communication is allowed.
For example, assuming that the container information includes a virtual IP address, if the virtual IP address of the first secure container and the virtual IP address of the second secure container are both located in the same first container information set, it may be determined that the first secure container and the second secure container belong to the same security domain, and communication is allowed.
For example, assuming that the container information includes a security domain identifier, if the security domain identifier DEV of the first secure container and the security domain identifier OA of the second secure container are both located in the same first container information set, it may be determined that the first secure container and the second secure container belong to the same security domain, and communication is allowed.
In the embodiment of the application, the boundary of the security domain is not limited by a physical environment, and the security domain can be accessed by configuring related information dynamic networking, so that the software definition and the self-adaptive adjustment of the boundary of the security domain are realized. The physical environment includes a physical network environment (e.g., a local area network, a metropolitan area network, a wide area network, the internet, etc.), a physical machine environment (e.g., an internal device, an owned device, a mobile device, an IDC room, etc.), and the like.
Specifically, the communication control policy may be further set as: allowing designated multiple secure containers within the same secure domain to communicate. For example, assuming that secure domain 1 includes secure container a1, secure container b1, secure container c1, secure container d1, and secure container e1, the communication control policy is: allowing secure container a1, secure container b1, and secure container c1, which communicate. Thus, the first set of container information includes container information for secure container a1, secure container b1, and secure container c1 that allow communication within secure domain 1.
Specifically, the communication control policy may also be set as a communication policy between security containers across security domains, that is, the first container information set includes container information corresponding to a plurality of security containers corresponding to different security domains. For example, assuming that secure container a1, secure container b1 and secure container c1 are included in secure domain 1, secure container a2, secure container b2 and secure container c2 are included in secure domain 2, if the first set of container information includes the container information of secure container a1 and the container information of secure container a2, then secure container a1 located in secure domain 1 and secure container a2 located in secure domain 2 are allowed to communicate. That is to say, the container information of the security containers corresponding to the different security domains is set in the first container information set, so that the purpose of controlling communication between different security domains is achieved.
More specifically, a communication range label may be set for each of the plurality of first container information sets, and a security domain range allowing communication may be characterized by the communication range label. For example, the communication control policy includes two first container information sets, and the communication range labels of the two first container information sets are: the label is used for representing intra-domain communication labels allowing communication among different security containers in the same security domain, and the label is used for representing out-of-domain communication labels allowing communication of different security containers across security domains. Wherein, the intra-domain communication label can be a domain label of the security domain; the out-of-domain communication tags may include domain tags for each of two or even more security domains. When the communication range label is applied, whether the communication is intra-domain communication or cross-domain communication is determined.
In the embodiment of the application, the current terminal acquires a pre-configured communication control policy from the server, so as to determine whether the first security container and the second security container allow communication according to the communication control policy.
In some embodiments, before step S104, the method further includes: step S1041 and step S1042 (not shown in the figure), and step S104 includes step S1043 (not shown in the figure).
Step S1041: determining a security domain to which the first security container belongs and a target application initiating communication operation in the first security container;
step S1042: determining whether the target application is an authorized application of the security domain based on an application program control strategy pre-configured in the security domain;
step S1043: and if the target application is determined to be the authorized application of the security domain, generating a communication request according to the container information of the first security container and the container information of the second security container.
In particular, the security domain configuration information upon which the first security container is created determines the security domain to which it belongs.
The container information corresponding to each of the plurality of secure containers of the current terminal is determined according to the security domain configuration information according to which each secure container is created and the virtual IP addresses obtained by the virtual network cards corresponding to each of the plurality of secure containers. Therefore, the container information corresponding to each of the plurality of security containers of the current terminal may include the virtual IP address and the security domain pointed to by the security domain configuration information. Therefore, the security domain to which the first security container belongs can also be determined from the container information of the first security container.
According to the method and the device, the application program allowed to run in the security domain is controlled through the application program control strategy, so that unauthorized application is prevented from running in the container.
For example, assuming that the first secure container includes an icon of the application program x, when a start operation of the icon of the application program x is detected, whether the application program x is a legal application of the first secure container is determined according to an application program control policy of the first secure container, if it is determined that the application program x is the legal application of the first secure container, the application program x is controlled to run in the first secure container, otherwise, the application program x is restricted from running in the first secure container.
In some embodiments, after the step of determining that the target application is an authorized application of the security domain in step S1043, the method further includes:
determining access control information corresponding to the target application based on an access program control strategy pre-configured in a security domain;
and controlling the target application according to the access control information corresponding to the target application.
In this embodiment, the target application may be an application program such as a browser and an instant messaging tool.
According to the embodiment of the application, the access control strategy is used for controlling the access address of the application program such as the browser, and the effect of limiting the access range of the application program such as the browser is achieved.
In this embodiment of the present application, the access control policy is used to characterize a network address of an application allowed in the security domain or a network address prohibited from being accessed, and the network address allowed to be accessed by the application may be represented in the form of an IP address, a port number, and a URL (Uniform Resource Locator).
For example, assuming that the access control policy includes a plurality of websites of the game web pages which are prohibited from being accessed, if the accessed address is the website of the game web page which is prohibited from being accessed, the website access request may be intercepted or the network interface may be closed; and if the accessed address is not the website of the game webpage which is prohibited to be accessed, sending the website access request to a server for providing service for the browser.

The electronic device may be a mobile terminal or a fixed terminal preinstalled with an operating system, such as a smart phone, a tablet computer, a desktop computer, and the like; the IDC server (i.e., internet data center) may also be used, for example, the IDC server generally includes a cloud, a central control room inside an enterprise, and the like. The application covers any suitable computer with an electronic device preinstalled with a Windows system, preferably a Linux system server.
In the embodiment of the present application, the electronic device includes a PC terminal 201, a PC terminal 202, a PC terminal 203, an IDC server 301, an IDC server 302, an IDC server 303, and an IDC server 304.
The following describes an interaction process between an electronic device and the trusted platform 100 by taking the PC terminal 201 and the IDC server 302 as an example.
The login process of the PC terminal 201 is:
when detecting the account login operation, the PC terminal 201 acquires an authentication credential input by the user. The authentication credentials typically include a username and a user password. The PC terminal 201 may verify the user identity of the user according to the locally stored registered user credential, or may send the authentication credential input by the user to the trusted platform 100, so that the trusted platform 100 verifies the user identity of the user. And if the user name and the user password are both correct, the user identity of the user passes the verification, and the user is a valid legal user. Under the condition that the user identity of the user is verified, the PC terminal 201 sends the device information of the PC terminal 201 to the trusted platform 100 to obtain a plurality of configuration-related information corresponding to the PC terminal 201, which is fed back by the trusted platform. After the PC terminal 201 acquires the configuration related information, it creates a container and a virtual encrypted disk of the container according to the security domain configuration information and the security domain key in the configuration related information, and creates a virtual network card for the container, so that the container acquires a virtual IP address through its virtual network card. To this end, the container creation processing is completed at the PC terminal 201, and it is determined that the PC terminal 201 completes the account login.
In a specific application, other PC terminals, such as the PC terminal 202 and the PC terminal 203, refer to the completed account registration of the PC terminal 201.
After the PC terminal 201 completes the account login, the PC terminal 201 acquires configuration information from the trusted platform 100, and thereby performs container creation processing on the PC terminal 201 to obtain a plurality of secure containers a11 and a12 operating in the PC terminal 201.
The login process of the IDC server 302 is as follows:
when the login operation of the IDC server 302 is detected, the authentication credential input by the user of the IDC server 302 may be acquired with reference to the PC terminal 201, and the user identity of the user of the IDC server 302 may be verified. After the verification is passed, the IDC server 302 sends the device information of the IDC server 302 to the trusted platform 100 to obtain the configuration-related information of the IDC server 302 fed back by the trusted platform 100. The IDC server 302 may include a physical MAC address, host information, and the like. After the IDC server 302 obtains the configuration related information, a container and a virtual encrypted disk of the container are created according to the security domain configuration information and the security domain key in the configuration related information, and a virtual network card is created for the container, so that the container obtains a virtual IP address through the virtual network card. To this end, the login of the IDC server 302 is completed. In particular, other IDC servers, such as IDC server 301, IDC server 303, and IDC server 304, may complete the login with reference to IDC server 302.
After the IDC server 302 completes account login, the configuration information is acquired from the trusted platform 100 by referring to the PC terminal 201, so that container creation processing is performed in the IDC server 302, and a secure container b11 and a secure container b12 running in the IDC server 302 are obtained. Thereafter, the IDC server 302 obtains the policies configured at the trusted platform 100, which may include communication control policies, application control policies, and access control policies, from the trusted platform. Wherein the communication control policy is configured to allow different security containers within the same security domain to communicate; the application control strategy is configured to be the application program allowed to run in the security domain; the access control policy is information such as accessible port, URL, etc. of the application allowed to run in the security domain.
In the embodiment shown in fig. 3, dashed boxes are used to characterize the same security domain. As shown in fig. 3, the PC terminal 201 is located in the same security domain as the IDC server 301 and the IDC server 302, and thus, the PC terminal 201 can communicate with the IDC server 301 and the IDC server 301 can communicate with the IDC server 302. The IDC server 304 is located in the same security domain as the IDC server 303 and can communicate with each other. The PC terminal 202 and the PC terminal 203 are located in the same security domain, and can communicate with each other. In the embodiment of the application, the communication transmission between different security containers in the same security domain adopts an encryption mode.
In fig. 3, the PC terminal 201 and the IDC server 304 are not located in the same security domain, and therefore, communication between the PC terminal 201 and the IDC server 304 is disabled. That is, whether the PC terminal 201 sends a communication request to the IDC server 304 or the IDC server 304 sends a communication request to the PC terminal 201, the trusted platform 100 performs the interception processing on the acquired communication request sent by the IDC server 304 or the communication request sent by the PC terminal 201.
