This invention discloses a group authentication and key negotiation method and system based on PUF, relating to the field of identity authentication technology. The method includes system initialization, drone registration, group authentication and key negotiation, secret share calculation and verification, key recovery, threshold adjustment, and dynamic group adjustment steps. This invention employs the aforementioned PUF-based group authentication and key negotiation method and system, achieving reliable drone identity authentication and secure negotiation of group session keys without relying on a trusted execution environment or dedicated security hardware modules, by introducing PUF and a verifiable secret sharing mechanism.

The present disclosure provides a kind of interactive method of browser tab group, it is related to computer technology field, the method includes: in response to the click operation of browser established tab group, the group homepage of tab group is displayed, and the group homepage includes list area, work area and fixed session area;The list area includes multiple tab entries and / or note entries;The work area is used to show web content or group note content, and fixed session area is used to show group session information associated with the tab group;In response to the trigger operation of target tab entry in the list area, display content corresponding to the trigger operation is displayed.The present disclosure can improve efficiency.

The application discloses a kind of unmanned aerial vehicle cluster decentralized inter-group key management method and system based on attribute encryption, which comprises the following steps: S1, initialization and main public key generation;S2, unmanned aerial vehicle attribute private key construction;S3, attribute encryption based on access policy and group session key encapsulation;S4, group session key decryption and recovery based on attribute private key;In addition, when unmanned aerial vehicle joins, exits or is revoked, the method also updates the key through the node revocation and key update steps, so that unauthorized nodes cannot obtain historical keys and cannot decrypt subsequent data, realizing the rapid trusted update of key.The application avoids the single point failure problem through the decentralized key generation and verification mechanism, combines the verifiable and tamper-proof characteristics of blockchain, and the attribute-based access control and dynamic key update strategy, improves the efficiency and credibility of inter-unmanned aerial vehicle cluster cooperative communication, and guarantees the security of data sharing in heterogeneous unmanned aerial vehicle network environment.

Provided are a content display method, device, equipment, computer readable storage medium and product. The method comprises: in response to ending a live broadcast operation of a social type, displaying a first display interface; displaying display content associated with the live broadcast operation in the first display interface, the display content comprising identification information of at least one first user performing a preset interactive operation in the live broadcast process and a processing control; and in response to a triggering operation of the processing control by a second user, adding the at least one first user to a session group. The method can more quickly and flexibly initiate a group session operation with the at least one first user. The display content in the first display interface is more suitable for the live broadcast of the social type, and the second user can more conveniently interact with the first user performing the preset interactive operation, thereby improving the user experience.

This application discloses a group session grouping method, apparatus, device, and storage medium, relating to the field of computer technology. The disclosed method includes: receiving a grouping request triggered based on the current group session; obtaining a public dictionary, which stores at least one grouping dictionary data identifying a group service group; selecting the corresponding target grouping dictionary data from the public dictionary according to the grouping request; and adding the current group session to the target group service group corresponding to the target grouping dictionary data. This application achieves grouping of group sessions by adding the current group session to the corresponding target group service group through the target grouping dictionary data in the public dictionary, thereby enabling users to query specified group sessions more quickly based on groups, improving query efficiency, and thus enhancing the user experience.
