Abstract]The security and reliability of the transmission of signals collected by the detection terminals and sensors of
great importance in the high-rail track signal detection system. However, the relevant signal processing device is limited in
computing power and it needs higher real-time requirements. Therefore a certificateless aggregate scheme and a new
adversary model are proposed. Under the random oracle model, it is proved that the scheme cannot be provably forged by
the adaptive chosen-message and adversary assumption attack. Moreover, compared with other existing aggregate signature
schemes like identity-based aggregate signature or certificateless aggregate signature with constant length in the
computational efficiency, the proposed scheme is more efficient as it doesn 't contain bilinear pairings. And this scheme is
more suitable for the application in secure signal transmission and data authentication service of the high-rail track
detection network system which has low bandwidth as well as limited storage and computing environment
