This paper proposed a new certificateless aggregate signature based on bilinear pairings. The proposed scheme was proved to be existential unforgeable against type Ⅰ and type Ⅱ adaptively chose message and identity attacks in the random oracle model. In the sign and verification algorithm,the scheme only needs three pairing computation and it meets all the properties of an aggregate signature,thus it is more efficient than the known schemes in terms of computation.
