#真签到题 from Crypto.Util.number import bytes_to_long, getPrime from secret import getflag p = getPrime(1024) q = getPrime(1024) n = p * q m = bytes_to_long(getflag().encode()) c1 = pow(m, p, n) c2 = pow(m, q, n) print(n) print(c1) print(c2) print(p) print(q)...
解题思路:首先通过代码审计,发现我们需要用get方法传递pleaseget变量值为1,用post方法传递pleasepost变量值为1,然后用post方法传递md51和md52的内容不同,但是md5值相同,这里就要利用php弱语言特性,0e123会被当做科学计数法,0 * 10 x 123。然后进行代码序列化。 md5(‘QNKCDZO’)的结果是0e830400451993494058024...

我们基于SIS构造Minicrypt,基于LWE构造Cryptomania。最近的一些研究成果显示,我们可以基于LWE构造更加高效的密码学方案。我不会讲这些内容,可能Chirs在他的讲座中会讲,我们拭目以待。但是如果我请大家仅凭直观感觉回答这样一个问题,我们应该怎么对格密码学进行密码学分析?如何基于问题的困难程度进行密码学分析?直观上看,...
