Encryption connection system, method, and portable cold therapy device

An encryption connection method, comprising:

• initiating an identity authentication request from a host module of a cold therapy system to a processing module;
• the processing module, according to the identity authentication request, acquiring identity information stored in an accessory module of a body wrap;
• the host module receiving the identity information returned by the processing module, and performing verification and matching on the identity information based on a preset verification rule;
• and
• the host module generating a control instruction according to a verification and matching result to control an operating state of the cold therapy system,
• wherein, when the verification and matching is successful, the host module authorizes the cold therapy system to start operation;
• when the verification and matching fails, the host module maintains the cold therapy system in a locked or off state.

A portable cold therapy device, comprising:

• a cold therapy system;
• a body wrap;
• and
• an encryption connection system, the encryption connection system comprising:
• an accessory module, disposed on the body wrap and configured to store an identity information;
• a processing module, connected to the accessory module and configured to acquire the identity information;
• and
• a host module, disposed in the cold therapy system and connected to the processing module, configured to acquire the identity information through the processing module and perform verification and matching,
• wherein the host module controls an operating state of the cold therapy system according to a result of the verification and matching.
