Threedecadesagopublic-keycryptosystemsmadea
revolutionarybreakthrough in cryptography. They have developed into
an indispensable part of our m- ern communication system. In
practical applications RSA, DSA, ECDSA, and similar public key
cryptosystems are commonly used. Their security depends on
assumptions about the di?culty of certain problems in number
theory, such as the Integer Prime Factorization Problem or the
Discrete Logarithm Problem. However, in 1994 Peter Shor showed that
quantum computers could break any public-key cryptosystembased on
these hard number theory problems. This means that if a reasonably
powerful quantum computer could be built, it would put essentially
all modern communication into peril. In 2001, Isaac Chuang and
NeilGershenfeldimplemented
Shor'salgorithmona7-qubitquantumcomputer. In 2007 a 16-qubit
quantum computer was demonstrated by a start-up company with the
prediction that a 512-qubit or even a 1024-qubit quantum computer
would become available in 2008. Some physicists predicted that
within the next 10 to 20 years quantum computers will be built that
are su?ciently powerful to implement Shor's ideas and to break all
existing public key schemes. Thus we need to look ahead to a future
of quantum computers, and we need to prepare the cryptographic
world for that future.
