Resumen
The invention relates to a system for slowing down the transfer rate of a device by the cryptographic method, including: a processing means (1) configured to: select a type of encryption; encrypt information according to the type of encryption selected, including: converting the information to be encrypted into a string of numeric characters, dividing the string of characters into blocks of a variable number of characters and encrypting each of the blocks according to the type of encryption selected; and randomly generating a plurality of codes. The system additionally includes: a memory (2) that stores the plurality of codes generated, the encrypted information and the operations and intermediate variables created by the processing means; and a means of input and output (3) configured to receive external information for carrying out the encryption tasks.
