Perhaps, after seeing quantum computers destroy RSA and DSA and ECDSA, Internet users will leap to the conclusion that cryptography is dead; that there is no hope of scrambling information to make it incomprehensible to, and unforgeable by, attackers; that securely storing and communicating information means using expensive physical shields to prevent attackers from seeing the information—for example, hiding USB sticks inside a locked briefcase chained to a trusted courier's wrist.

也许，在看到量子计算机攻破RSA和ECDSA后， 互联网用户觉得密码学已过时了。他们不再相信 加密信息能抵抗攻击者理解或伪造信息。安全存 储和交流信息意味着使用昂贵的物理屏蔽防止攻 击者看到信息，例如，将USB藏于带锁的公文包 里，并将公文包拴在可信快递员的手上。

Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary. It is theoretically possible to break such a system but it is infeasible to do so by any known practical means. These schemes are therefore termed computationally secure; theoretical advances (e.g., improvements in integer factorization algorithms) and faster computing technology require these solutions to be continuously adapted. There exist information-theoretically secure schemes that provably cannot be broken even with unlimited computing power—an example is the onetime pad—but these schemes are more difficult to implement than the best theoretically breakable but computationally secure mechanisms.
