我正在做一个关于密码学的在线免费课程,有一个非常令人困惑的问题:
有人能解释一下答案吗?
Question for hashing algorithms:
Select one or more than one.
a. It is impossible to break its resistance to collision and preimage
b. It is more difficult to break its resistance to collision than to the preimage
c. It's just as easy to break your r
就安全而言,这是一个更好的选择:
1) cheaper option - vps (Iam assuming that if one particular virtual server is hacked,then still other virtual servers on that comp will be safe)
2)区别对待。代理数据库服务器(但它毕竟可以被黑客攻击,对吗?)
3)或..。做两个不同的事情。服务器在同一台计算机上侦听差异。端口!(将dis称为共享服务器条件)
我是否正确地假定了vps和dedctd服务器?第三个案子呢?请澄清我的疑
