An encryption and decryption method in a virtualization system, where the virtualization system includes a virtual machine monitor (VMM) and an encryption and decryption virtual machine. The VMM includes a control module, the encryption and decryption virtual machine records a first association relationship between a hard disk image identifier and a key, the key includes an encryption key, and the virtualization system records a second association relationship between the hard disk image identifier and a hard disk image attribute. The control module in the VMM is configured to determine whether to-be-written data needs to be encrypted and forward the to-be-written data, which reduces system complexity of the VMM. In addition, encryption or decryption is processed without occupying a resource in the VMM.

Encryption and decryption method and apparatus in virtualization system, and system

A method for clicking and selecting an object in a three-dimensional virtual reality scene is provided. The method includes: receiving a positioning signal of a target object in a three-dimensional virtual reality scene; projecting the target object to a set position in a display window according to the positioning signal; if the target object is displayed at the set position, after a behavior for clicking the target object is perceived, acquiring two-dimensional coordinates corresponding to a clicking position in the display window; determining a single object corresponding to the clicking position according to the two-dimensional coordinates; acquiring a leaf node corresponding to the single object in a tree management structure, and acquiring a father node of the leaf node; if the attribute of the father node is unlock, selecting the single object; if the attribute of the father node is lock, tracing a node from the father node along the direction towards the root node of the tree management structure, wherein the node is closest to the father node and the attribute of the node as a father node is unlock, and selecting a combined object corresponding to the node. Also, a device for clicking and selecting an object in a three-dimensional virtual reality scene is provided.

Method and device for clicking and selecting object in three-dimensional virtual reality scene

An encryption and decryption method in a virtualization system is disclosed. The virtualization system includes a VMM and an encryption and decryption virtual machine. The VMM includes a control module, the encryption and decryption virtual machine records a first association relationship between a hard disk image identifier and a key, the key includes an encryption key, and the virtualization system records a second association relationship between the hard disk image identifier and a hard disk image attribute. The control module in the VMM is configured to determine whether to-be-written data needs to be encrypted and forward the to-be-written data, which makes it easy to implement a function and reduces system complexity of the VMM. In addition, encryption or decryption is processed without occupying a resource in the VMM.

The invention provides a cable connector component, a board connector component, and an electric connector assembly thereof. The cable connector component includes a connector, a fixed iron shell, and a cable including a plurality of core wires. The connector includes at least one pair of terminal pair, a first insulating body, a first metal shell, a group strip, and a printed circuit board. The terminal pair, the ground strip, and the first metal shell are assembled with the first insulating body. The first metal shell is assembled with the fixed iron shell. The fixed iron shell includes a convex hull which facilitates the cable to insert into the fixed iron shell. The board connector component, includes: a second metal shell including a butting chamber, a terminal group and a second insulting body which are fixed in the second metal shell. The second insulting body includes a base and a clapper disposed at a front end of the base. The clapper includes a first surface and a second surface which are disposed oppositely. A shielding plate is disposed between the first surface and the second surface, and the shielding plate includes a protrusion which is extended out of a side of the base and abuts against the second metal shell. As a result, a new grounding path is formed, which can reduce the electromagnetic interference and strengthen the insulating effect.
