Yesterday, all sixth-grade class graduated according to photos, and schools are very busy all day, like a market, they are coming to graduation as a happy thing, had just eaten dinner at noon today, a large group of children running to the office came to me and Denis graduated according to their sign, the first time I realize the "stars" of the feeling of being surrounded by the signature, according to the back of a long graduated from the teachers and students full name, appears to have the same graffiti Art feeling, numerous signature reminds me of when I graduated last year, was both pleased and full of melancholy, reminds me when we separated from the sentimental and emotional, but now they also experience less than classmates, friends, respectively, the unrounded, perhaps in a number of years later, when the time to re-look at photos of them slowly recalled when primary school life, learning time, recalled the story of childhood

This paper has obtained following three results about the new scheme:(1) The hardness of recovering the private key from the public key is based on the hardness of the shortest vector problems of several lattices;(2) The hardness of forging a signature is equivalent to the hardness of the closest vector problem of some lattice;(3) Each signature will leak information on the private key,but the final shape of the unlimited leakage is just a group of complicated non-linear equations.

文中给出新方案的3个结果：(1)由公钥恢复出私钥的困难性基于若干格上的最小向量问题；(2)由公钥伪造签名的困难性等价于某个格上的最近向量问题；(3)每个签名值仍然会泄露私钥的一些信息，但无限制泄露的最终形式只是关于私钥的一组复杂的非线性方程。
