2901 results about "Terminal server" patented technology

A terminal server enables organizations to connect devices with an RS-232, RS-422 or RS-485 serial interface to a local area network (LAN). Products marketed as terminal servers can be very simple devices that do not offer any security functionality, such as data encryption and user authentication. The primary application scenario is to enable serial devices to access network server applications, or vice versa, where security of the data on the LAN is not generally an issue. There are also many terminal servers on the market that have highly advanced security functionality to ensure that only qualified personnel can access various servers and that any data that is transmitted across the LAN, or over the Internet, is encrypted. Usually companies which need a terminal server with these advanced functions want to remotely control, monitor, diagnose and troubleshoot equipment over a telecommunications network.

Ciphertext cloud storage method and system

The invention relates to a ciphertext cloud storage method and system. In the ciphertext cloud storage method system composed of at least one client terminal and a cloud terminal server, the ciphertext cloud storage method comprises the steps that (1) a user adopts a ciphertext and / or a plaintext to conduct data synchronism on the client terminal in the process of data storage and selects an encryption algorithm for the ciphertext; (2) authentication parameters provided based on the identity of the user is used for generating a master key, synchronous data of the ciphertext are encrypted on the client terminal through two-level keys comprising the master key and an encryption and decryption key, and the master key is backed up; (3) the ciphertext and a ciphertext index are synchronized on the client terminal and a cloud terminal, or a plaintext index is established after synchronous data of the plaintext are synchronized on the cloud terminal and the client terminal; (4) the plaintext and / or ciphertext is / are stored in a local private cloud storage server or in a storage server of a cloud storage provider according to a mount point requested by the user. By the adoption of the ciphertext cloud storage method and system, the data cannot be lost when the terminal is lost, if protection is inappropriate, only the ciphertext form of a file is damaged, and the ciphertext cloud storage system can dock with multiple cloud server providers.
