Abstract: This application discloses a private key generation method and system, and a device. The method includes: sending, by a first network device, a first request to a second network device, where the first request includes a first parameter set; receiving, by the first network device, a first response message returned by the second network device, where the first response message includes a first sub-private key and a second parameter set, the first sub-private key is generated based on the first parameter set, and the first sub-private key is generated for a terminal device; generating, by the first network device, a second sub-private key based on the second parameter set, where the second sub-private key is generated for the terminal device; and synthesizing, by the first network device, the first sub-private key and the second sub-private key into a joint private key according to a synthesis formula.
