Summary In this letter, a practice‐oriented lottery protocol that allows a player to select t from the pre‐defined n elements is proposed using the method of oblivious transfer and Lagrange interpolation polynomial. Each player can verify if its contribution is really involved in generating the final result without other's collaboration. Next, neither the delaying function nor the trusted third party is necessary in the proposed protocol, which guarantees the protocol more robust and efficient. Furthermore, the proposed protocol is more practical without the assumption that n should be small. Copyright © 2014 John Wiley & Sons, Ltd.
