Abstract

Secure communication is an essential need for companies, public institutions, and in particular the individual citizen. Currently used encryption systems are vulnerable due to the increasing power of computer technology, the emergence of new codebreaking algorithms, and the imperfections of public key infrastructures. Methods considered as acceptably secure today will have a significant risk of becoming weak tomorrow. On the other hand, with quantum cryptography, a technology has been developed within the last decade that is provably secure against arbitrary computing power, and even against quantum computer attacks. When becoming operational, quantum cryptography will raise communication security to an essentially higher level.
