1.2 扩展欧几里得算法 扩展欧几里得算法(英语:Extended Euclidean algorithm)是欧几里得算法(又叫辗转相除法)的扩展。已知整数a、b,扩展欧几里得算法可以在求得a、b的最大公约数的同时,能找到整数x、y(其中一个很可能是负数),使它们满足贝祖等式 ax+by=gcd(a,b).ax+by=gcd(a,b). 如果aa是负数,可以把问题转化...
RSA algorithm is a process of encrypting plain text in blocks, every block has a binary value lesser than some n number. The size of block should be less than log (n) or equal to log (n), public-key cryptosystem was implemented by RSA algorithm In this Journal we are going to...
设p,q是两个超级大的素数,N=pq,数据通过欧拉函数φ(N)来加密,而欧拉函数φ(N)满足φ(N)= φ(pq)=(p-1)(q-1),如果要算出φ(N),就必须知道p和q。并且这有一点好处,某人可以公开宣布他的密钥e以及N,任何人都可以给他发送密文,但是只有他能看懂。因为想要破解密码,就必须知道那两个超级大素数p,q....
DES3,通常指的是三重数据加密算法(Triple Data Encryption Algorithm,3DES)或称为Triple DES,是一种对称加密算法。它是基于原有的DES(Data Encryption Standard)算法扩展而来,通过三次DES加密来增强安全性。 BUG弄潮儿 2024/05/11 4840 从小白变RSA大神,附常用工具使用方法及CTF中RSA典型例题 数据加密服务编程算法 ...
