Tóm tắt:  In 1999, Poupard and Stern proposed on the fly signature scheme (PS-scheme), which aims at minimizing the on-line computational work for a signer. In this paper, we propose more efficient on the fly signature schemes by improving the PS-scheme. In PS-scheme, the size of secret-key is fixed by modulus n, so that this feature leads to some drawbacks in terms of both the computational work and the communication load. The main idea of our schemes is to reduce the size of secret-key in PS-scheme by
