<p>The present invention discloses a method and a system for authentication via a communication terminal using short messages, in order to solve the problems that the content of a short message is easy to be leaked out by a proxy SP and that the loss and delay of a short message may lead to repeating user payments. The method includes: sending, by the communication terminal to a payment system via an SP1, a short message payment request including a payee's account identifier and a payment amount; creating, by the payment system, a payment record corresponding to the request and sending verification information to the communication terminal via an SP2, the verification information including the payee's account identifier and the payment amount; replying, by the communication terminal, confirmation information to the payment system via the SP2, upon confirming that the payee's account identifier and the payment amount in the verification information are correct; and performing, by the payment system, a payment operation. The present invention uses a dual channel (SP1 and SP2) asynchronous transmission mechanism. The situation where any one of the channel is illegally controlled and thus short message information is leaked out can be prevented and the user can cancel a repeated payment in confirmation of the payment.</p> |
