[edit] Guardian Discovery
A Reader that suspects or desires presence of an RFID Guardian will perform the Guardian Discovery protocol. For each of the candidates in its current tag list, it will perform something like the following handshake protocol. First, it gets its partner's block size and number of blocks. Then, it reads a number of bytes from some well-known block location. If the bytes match some pattern (think of the string 'RFID Guardian'), it attempts to write a well-defined pattern to some other block location. If this also succeeds, the Reader and Guardian try to set up an SSL connection over the RFID channel. During this SSL connection establishment, the Reader authenticates itself, and it may request authentication from the Guardian.
Depends on:
- Guardian SSL
- One of the steps in discovery is SSL authentication.
