Quantum cryptography -- an information theoretic security
Muhammad Nadeem
Methods of quantum mechanics promise information-theoretic security for various protocols in cryptography. However, impossibility of some cryptographic applications such as standar…
Quantum digital signature scheme
Muhammad Nadeem, Xiaolin Wang
Digital signatures are the building blocks of modern communication to prevent masquerading by any party other than recipients, repudiation by signatory and forgery by any individua…
Secure and authenticated quantum secret sharing
Muhammad Nadeem, Noor Ul Ain
We propose here a quantum secret sharing scheme that works for both quantum and classical secrets. The proposed scheme is based on both entanglement swapping and teleportation toge…
The causal structure of Minkowski space time: possibilities and impossibilities of secure positioning
Muhammad Nadeem
Secure positioning, a prover located at a specified position convinces a set of verifiers at distant reference stations that he/she is indeed at the specific position, is considere…
Delayed choice relativistic quantum bit commitment with arbitrarily long commitment time
Muhammad Nadeem
We propose here a two-round relativistic bit commitment scheme where committer commits in the first round and then confirms his/her commitment in the second round. The scheme offer…
Quantum non-locality, causality and mistrustful cryptography
Muhammad Nadeem
Here we propose a general relativistic quantum framework for cryptography that exploits the fascinating connection of quantum non-locality and special theory of relativity with cry…
