Basically needing an encryption module to use a key to encrypt a set of operating messages/API into encrypted messages, then after passing through it, it is decrypted using a key, and used by a secondary processes or devices to execute instructions or messages/data. This is to protect the data from one device, that docks onto another station for data retrieval etc. So basically, encoding messages or information in such a way that only authorized parties (docking stations and perhaps a reader) can read it.
