Quantum cryptography
Vulnerabilities of quantum cryptography on geometrically uniform coherent states
D. A. Kronberg Steklov Mathematical Institute of Russian Academy of Sciences, Moscow
Abstract:
It is shown that the quantum cryptography protocol on geometrically uniform coherent states, which uses the restriction for unambiguous discrimination of a set of symmetric coherent states and allows resisting an unambiguous state discrimination attack (USD attack), is not secure to a number of other attacks. The key length formula from the work of S.N. Molotkov [JETP Lett., 101 (8), 579 (2015)] and the key generation rate for a number of constructive attacks of the eavesdropper are compared and it is shown that the key generation rate in this work is significantly overestimated. This leads to the fact that the distributed key is not secret.
Keywords:
