还有一个缺陷就是在只知道密文 x 及公钥(n,e)的情况下,只要将 (x^e) mod n 所得余数 s 再不断地循环操作 s = s^e mod n,此运算不断地循环 e 次之后,很多情况下都可以循环出原文,只是计算量过余多一些罢了。不过有不少情况下,根本都无须循环 e 次,不过对于1024位的 n 级别来说,e 也是一个相当大的数值,所以循环密文的余数以解得原文是有些不现实。 以上内容仅供参考,如有不实,请予更正-there is a defect in only know that the secret and public key-x (n, e) the circumstances, as long as (x ^ e) mod n from the remaining s to continuously cycle operation s = s ^ e mod n, this constant cycle of Operational e occasion, the very many circumstances can be recycled from the original, but I calculated the volume more than just. There are, however, many instances, simply do not need e cycle times, but for 1024 the level n, e is a very large figure, so secret circle the remainder of the text was obtained in the original is a bit unrealistic. The above is for reference only, if not true, I corrected

    软件工程是计算机专业硕士阶段的学位课程之一,对以软件工程为专业培养方向的硕士生而言尤为重要。由于计算机相关专业的本科阶段已开设过此课程,并且软件工程课程自身具有综合性强等特点,为硕士阶段软件工程课程的教学内容和培养目标等环节带来了一些挑战。本文立足于计算机相关专业的硕士教学阶段,分析硕士阶段开设软件工程课程所面临的问题,从课程设置和培养目标两方面入手,提出了几点关于软件工程课程教学的建议。-Software engineering is a computer science master" s degree phase of the one right in the direction of software engineering for professional training is particularly important in terms of the Master. As a professional computer-related undergraduate stage set up over the course, and the software engineering curriculum itself has a comprehensive and strong features of the software engineering courses for the master stage of the teaching content and training objectives of such links has brought some challenges. This article is based on computer-related professional master" s teaching stage, analysis stage master of software engineering courses set up the problems faced by the curriculum and training objectives from the two-pronged approach to put forward a number of points on the software
