Cryptographic assumptions: a position paper
WebThis is exactly the question that we resolve in this paper. That is, we investigate the possibility of doing position-based cryptography in the quantum setting. We present schemes for several important position-based cryptographic tasks: positioning, authentication, and key exchange, and we prove them Web@article{eprint-2015-26216, title={Cryptographic Assumptions: A Position Paper}, journal={IACR Cryptology ePrint Archive}, volume={2015}, pages={907}, …

Did you know?
WebThe mission of theoretical cryptography is to define and construct provably secure cryptographic protocols and schemes. Without proofs of security, cryptographic constructs offer no guarantees whatsoever and no basis for evaluation and comparison. As most security proofs necessarily come in the form of a reduction between the security claim … WebMar 24, 2014 · Download PDF Abstract: In this paper, we propose quantum position-verification schemes where all the channels are untrusted except the position of the prover and distant reference stations of verifiers. We review and analyze the existing QPV schemes containing some pre-shared data between the prover and verifiers. Most of these …

Webof position-based cryptographic tasks. We first construct a protocol for information theoretic secure positioning in this model. To our knowledge, this is the first protocol which is secure even against collusion attacks. Although secure positioning is an important step, the full power of position based cryptography can only be realized if we achieve key …
