In this section, you can configure the following parameters: 

Available security levels (depending on profile type):

  • none: there is no need to encrypt cards. Only UID and chip manufacturer information will be sent to the controller; 

  • SL1 6 bytes;

  • SL1 diversifying;

  • SL3 diversifying: used for authentication, data exchange, and encryption, for working with memory, as well as for detecting remote attacks by radio channel. AES crypto-algorithm is used; 

  • SL3 16 bytes: more secure applied encryption algorithm. The principle of the algorithm is that each identifier has its own individual encryption key.

Available options: 

  • if the card code option is selected and the encryption key (of the recorded cell) in the card matches the encryption key in the reader, then the card code (UID) will be sent to the controller;

  • if the by address option is selected, the information recorded in a certain memory block of the card will be sent from the reader to the controller.

note

Mifare Plus chips (in cards, keychains, bracelets, etc.) are at the SL0 security level by default. It is impossible to use cards at the SL0 level in the application system, the Mifare Plus chip must be upgraded to SL1, SL2, or SL3. When initializing the Mifare Plus chip, the object owner must generate the key values and store this information securely.
