Abstract: The present application discloses a key updating method and apparatus, a file sharing method and apparatus, a device, and a computer storage medium. The key updating method includes: acquiring a target root key and an auxiliary target root key; acquiring the identity information of a data owner of target data; acquiring a target timestamp when the target data is encrypted; acquiring a key generation parameter and an auxiliary key that are generated at a timestamp previous to the target timestamp; generating a target private key of the data owner on based on the key generation parameter and auxiliary key of the timestamp previous to the target timestamp, the identity information and the target timestamp, the key generation parameter generated at the timestamp previous to a starting timestamp being the target root key, the auxiliary key generated at the timestamp previous to the starting timestamp being the auxiliary target root key.

Abstract: The present invention provides a method and a system for negotiation based on IKE messages. A standby device updates a value of a stored third identity according to an update notification of an active device. The update notification of the active device is sent by the active device after updating a value of a stored second identity. When the standby device switches to a new active device, the new active device sends a second message for negotiating IPSec information to a peer device according to the updated third identity. The third identity is an identity that is stored in the standby device and used to acquire state information of the active device.

Abstract: A system for processing packets in a distributed architecture system includes a main control board, at least one service board, and at least one interface board. The system determines a specified CPU corresponding to a received packet; and, by the service board corresponding to the CPU, processes the received packet. The received packets are processed in the service board corresponding to the specified CPU. Therefore, the packets are evenly distributed to all service boards for being processed, the workload of the main control board is relieved, the service throughput is increased significantly, and the packet processing efficiency of the whole architecture is improved.
