摘　　要：This paper presents two practical message commitment schemes: one is suitable for committing many bits, and another is useful for committing any bit-long message. They are provably secure based on pseudo-random synthesizers. In these schemes, the sender may be unbounded to polynomial time and the receiver is bounded. The advantage of these schemes is that the secure parameter may be small.This paper presents two practical message commitment schemes: one is suitable for committing many bits, and another is useful for committing any bit-long message.
