Key generation method, event scheduling method, system and terminal equipment

The invention discloses a key generation method, an event scheduling method, a system and terminal equipment. The key generation method is used for terminal equipment, the terminal equipment comprises a plurality of microcontrollers, any two microcontrollers are respectively marked as a home terminal and an opposite terminal, and the key generation method comprises the following steps: the opposite terminal generates a first opposite terminal private key, a first opposite terminal public key and a second opposite terminal public key, the second opposite-end public key is signed according to the first opposite-end private key to obtain a signed second opposite-end public key, and the signed second opposite-end public key and the first opposite-end public key are packaged and sent to the home terminal; and the home terminal performs signature verification on the signed second opposite-end public key according to the first opposite-end public key to obtain the second opposite-end public key, and generates a secr
