Establish an AES-authenticated and encrypted connection

Try the app note

The app note appnotes\secure_communication in the SDK gives you a working example of the implementation (learn more about app notes).

To establish an AES-authenticated and encrypted connection run the following commands in your protocol stack before connecting to the reader with brp_open():

int security_level = 1; // A security level 
  defines a set of permissions for the host application. Specify the 
  number of the security level (1, 2, or 3) as defined in the 
  reader configuration.

brp_sec_key key = { 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, }; // The AES encryption key for the security level, as defined in the 
  reader configuration

int security_mode = BRP_SECMODE_STD; // We recommend the default value 
  BRP_SECMODE_STD.

errcode = brp_set_crypto(dev, brp_create_secure_channel(security_level, key, security_mode)); // 
brp_create_secure_channel() creates an AES-authenticated and encrypted channel. Pass it to 
brp_set_crypto() to assign the crypto protocol object to your protocol stack.
