The invention discloses a management method of self-certified public key of a mobile self-organized network on the basis of ECC, comprising the following steps: a shared key is distributed to n virtual central nodes by threshold cryptology; a user chooses a secret random number to calculate a public parameter, and identity and the public parameter are sent to a nearby virtual central node A1; A1 contacts with other virtual central nodes and sends the user information to the nodes; each publisher Ai chooses a random secret integer and calculates as well as broadcasts a self-certified public key subblock Qi to other publishers according to the secret integers and parameters published by the user; each publisher Ai calculates a self-certified public key Q, a sub-signature xi and an intermediate quantity Ri and sends (r, I, xi and Ri) to a synthesizer; the synthesizer calculates and synthesizes a signature x after all sub-signatures are qualified after authentication and sends Q and x to the user; the user calculates a secret key s according to the x; and the authenticity of the self-certified public key of the user is verified. The invention has no certificate management, no key escrow and no secure channel, so that the invention is suitable for the safe communication of the mobile self-organization network with limited resource.
