Methods of using NVM to improve performance of cryptographic file system

The invention discloses methods of using NVM to improve performance of a cryptographic file system. Dynamic planning is carried out according to data block features of a file writing request, a suitable soft or hard calculation method is selected to execute an encryption operation, then ciphertext is written into an NVM cache, and finally, ciphertext data in the NVM are collectively written back to a disk layer by a background thread in a manner of asynchronous IO. NVM memory space is allocated and managed by an NVM memory management strategy. A storage location of requested data is quickly queried according to the NVM memory management strategy, a decryption operation is carried out on read ciphertext by selecting a suitable soft or hard calculation method by a dynamic planning method, and finally, plaintext is returned to an upper-layer application. Compared with manners in which the need for calling hardware engines for multiple times and waiting for data writing-back to disks causes delay in traditional eCryptfs data encryption / decryption, the method can effectively reduce mode context switching overheads of hardware and delay due to IO speed mismatching, improves application of a hardware encryption engine, and also improves overall performance of the cryptographic file system.

Multi-process production method, application and system of ready-made and ready-to-sell food based on communication control

A multi-process production method for on-the-go and sold food based on communication control, comprising the steps of: defining a control command protocol for each food processing equipment involved in the food production process; defining a control command protocol for each food processing equipment according to food taste Combine to form the control command protocol combination list corresponding to the processing procedures of different food tastes; call the corresponding control command protocol combination list according to the obtained food taste production command, and press each control command protocol in the control command protocol combination list The processing procedure is sent to the corresponding food processing equipment, so that the food processing equipment executes the corresponding food processing action according to the received control command protocol. Since the control commands of each food processing equipment are sent by communication, the seamless connection between the front and rear processing procedures is realized, and some processing procedures can be executed synchronously, which shortens the food processing cycle and further shortens the waiting time for purchasing ready-made food. There is the problem of long waiting times for buying freshly prepared food.
