Ideally, cryptographers should only look at ciphers that have a reasonable chance of being secure.
理想情况下，密码学家只会关注那些有合理的机会成为安全算法的东西。
DES has been studied by many of the world's leading cryptographers, but no weaknesses have been uncovered.
世界上许多主要的密码学家对des进行了研究，但至今未发现它的薄弱之处。
Dr Shields's photon detector, however, permits cryptographers to use a phenomenon called quantum entanglement to make a repeater that does not destroy quantum states.
然而，Shields博士的量子探测器使用了一种被称为量子纠缠的现象，可以允许密码专家制造一种不破坏量子态的中继器。
A while ago an AD hoc group of computer scientists and cryptographers contributed to a paper that recommended a key of at least90bits for symmetric algorithms used in commercial security.
不久前，计算机科学家和密码学家专门小组发表了一篇论文，建议用于商业安全的对称算法至少要用90位的钥匙。
The simplest example is when the sender (whom cryptographers usually call Alice) dispatches a stream of them to the receiver (who is known as Bob). These photons will have one of two modes.
举个最简单的例子，当发送方将一束光子流传送给接受方，必须从两种模式中的选取一种对其中的光子进行编码（译码者通常称发送方为爱丽丝，接受方为鲍勃）。
