Abstract: Method and device of encrypting communication between a server and a peripheral device are disclosed. The method includes: a server receiving a session request from a control device, the session request including a predetermined device ID of a peripheral device associated with the control device; generating a first session key for encrypting and decrypting future communication between the peripheral device and the server; identifying a pre-stored encryption key corresponding to the predetermined device ID from a database, wherein the pre-stored encryption key is also pre-stored in the peripheral device; encrypting the first session key using the pre-stored encryption key; sending the encrypted first session key to the peripheral device via the control device; and encrypting communication to the peripheral device in a respective communication session using the first session key.
