Unconditionally secure commitment in position-based quantum cryptography
A new commitment scheme based on position-verification and non-local quantum correlations is presented here for the first time in literature. The only credential for unconditional security is the position of committer and non-local correlations generated; neither receiver has any pre-shared data with the committer nor does receiver require trusted and authenticated quantum/classical channels be...
متن کاملAnonymous key quantum cryptography and unconditionally secure quantum bit commitment
A new cryptographic tool, anonymous quantum key technique, is introduced that leads to unconditionally secure key distribution and encryption schemes that can be readily implemented experimentally in a realistic environment. If quantum memory is available, the technique would have many features of public-key cryptography; an identification protocol that does not require a shared secret key is p...
متن کاملUnconditionally secure cryptosystems based on quantum cryptography
Most modern cryptographic studies design cryptosystems and algorithms using mathematical concepts. In designing and analyzing cryptosystems and protocols, mathematical concepts are critical in supporting the claim that the intended cryptosystem is secure. Most early cryptographic algorithms are based either on factorization or on discrete logarithm problem. Such systems generally adopt rather s...
متن کاملUnconditionally Secure Cryptosystem Based on Quantum Cryptography
Most cryptographic works these days have employed mathematical concepts to design cryptosystems and algorithms. Therefore, mathematical concepts have become critical in the designing of cryptosystems, and are generally used to analyze cryptosystems and protocols, supporting the allegation that the intended cryptosystem is secure. In earlier cryptosystems, most algorithms were based on either fa...
متن کاملUnconditionally Secure Quantum Bit Commitment
Lo and Chau, and independently Mayers, have shown that all quantum bit commitment schemes proposed to date are insecure: one or both participants can cheat if they have a quantum computer. They claim also to have demonstrated that unconditionally secure quantum bit commitment is impossible. However, their no-go arguments rely on models of quantum cryptographic protocols which are insufficiently...
