description The invention provides an anonymous authentication method based on certificateless group signature in Internet of Vehicles. The anonymous authentication method comprises the following steps: initializing a system; generating public and private keys of the group administrator and the group members; carrying out member joining: wherein newly joining members join in the existing Internet of Vehiclesgroup according to a group joining method, generate own synchronization factors and update the group synchronization factors, the group administrator verifies the legality of the identity of the newlyadded member and generates a certificate for the newly added member, and the newly added member verifies the legality of the identity of the group administrator and accepts the own certificate, the group administrator publishes a new synchronization factor, and other members in the group update own synchronization factors; carrying out signature generation: the group members realize signature ofthe message based on a sign
