Quantum Cryptography - Essay Example Both properties form a third strength of quantum cryptography in terms of security. This strong point occurs from every new QKD term code being free of all formerly used codes as this independence lowers the number of methods a criminal can infiltrate the system (Cobourne and Cid, 2011, p. 5). A fourth strength is the future proofing of security offered by QKD. Even when a malefactor breaks through a cryptographic system at any indefinite period in the future, former messages conveyed through it stay secure (Cobourne and Cid, 2011, p. 5). Mathematics has demonstrated the absolute security of QKD networks. Even when dealing with a rival that has endless supplies of time and energy, security of QKD networks are unbreakable. One weakness of quantum cryptography is that quantum mediums are only functional over limited space (Rothke, 2007, p. 1055). This is a technical weakness as it occurs when one evaluates the realities of QKD application. Today, quantum mediums cannot convey data quick enough to offer sufficient levels of service, which forms a second technical weakness. Thirdly, quantum optic gear is susceptible to attacks. Quantum cryptography requires costly setups for upholding quantum processing, which serves as a weakness for mathematics, computer, and physics researchers who cannot afford such infrastructure (Cobourne and Cid, 2011, p. 6). Another weakness is the possibility of quantum cryptography â€Å"killing† mathematical progressions at any period in the future irrespective of quantum computing advancements (Rothke, 2007, p. 1055). Commercially, the promise of ideal security may not be a significant enough imperative for businesses to permit the cost of customized gear and infrastructure (Nano 2014). Since conventional cryptography offers more than sufficient security, businesses will consider the uncertain advantages of quantum cryptography an unworthy risk and weakness (Lydersen et
