Phys. Rev. A 68, 026301 (2003) [2 pages]Comment on “Quantum identification schemes with entanglements”
Wim van Dam * Received 5 February 2003; published 28 August 2003 In a recent paper, Mihara [Phys. Rev. A 65, 052326 (2002)] presented several cryptographic protocols that were claimed to be quantum mechanical in nature. In this Comment, it is pointed out that these protocols can be described in purely classical terms. Hence, the security of these schemes does not rely on the usage of entanglement or any other quantum-mechanical property. ©2003 The American Physical Society
