A method for protecting information in a data transmission system includes placing in a cryptographically protected part of the device memory encoded with a key generated using private user information regarding registration, keys and information transmission protocols. To access restricted data, a random data block is generated, an electronic key is simultaneously generated based on the user's password and, based on the key resulting from the pseudorandom function of two arguments from the electronic key and the random data block, a random local encryption key is created, which is unique for each account. Each local encryption key is set to a pseudorandom key - a function of three arguments: user ID, user password key, and user registration ID, and is written to a block of permanent memory.
