The encryption algorithms provided by CryptoAPI Linux for choosing the most efficient to work with encryption and decryption of data on USB-drives are investigated. A classification of such algorithms is given, their advantages and disadvantages, as well as criteria for algorithms estimation, are indicated. The study of the algorithms speed characteristics depending on the performance of the processor has been carried out. A comparison of the selected algorithms with similar algorithms by performance has been conducted. The main system calls of CryptoAPI Linux are considered, as well as ways to register the driver in the Linux operating system and its interaction with system devices. A description of the model of interaction with USB storage system is given.
