One time pad generation using quantum superposition states
Gaurav K. Upadhyay, Manisha J. Nene · 2016
Modern cryptography offers three goals of Confidentiality, Integrity and Availability, known as CIA triad. Confidentiality of any message or communication is secrecy of its content. All the modern cryptosystems provide cryptographic secrecy and not perfect secrecy. Two ingredients of perfect secrecy are truly random source and secure communication channel. Both are available in quantum computing paradigm. However, Quantum Computers are not yet commercially available. Certain time-tested cryptographic techniques in classical computing can be combined with principles of quantum computing to to achieve the goal of perfect secrecy. Theoretically, One Time Pad (OTP) is proven to be unconditionally secure. The paper suggests an hybrid approach to cryptography by generating OTP using quantum superposition states. The results of OTP generation are corroborated with theoretical values. The OTP so generated by realization of the suggested approach on a classical system is found to pass the test for randomness.
