Enhanced (t, n) threshold d-level quantum secret sharing

Scientific Reports, 2021
The quantum secret sharing is an essential and fundamental technique for sharing a secret with the all participants in quantum cryptography. It can be used to design many complex protocols such as secure multiparty summation, multiplication, sorting ...

Full-field implementation of a perfect eavesdropper on a quantum cryptography system [PDF]

, 2011
Quantum key distribution (QKD) allows two remote parties to grow a shared secret key. Its security is founded on the principles of quantum mechanics, but in reality it significantly relies on the physical implementation.

The Case for Quantum Key Distribution [PDF]

, 2009
Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures.

Multi-Party Threshold Cryptography

, 2023
AbstractIn a threshold cryptosystem, the private key is typically distributed among parties that constitute the system using cryptographically secure secret sharing. Particular focus must be placed on generating the private key held jointly by the parties.

Ensuring patients privacy in a cryptographic-based-electronic health records using bio-cryptography [PDF]

, 2017
Several recent works have proposed and implemented cryptography as a means to preserve privacy and security of patients health data. Nevertheless, the weakest point of electronic health record (EHR) systems that relied on these cryptographic schemes is ...

Security of two-way quantum cryptography against asymmetric Gaussian attacks

, 2008
Recently, we have shown the advantages of two-way quantum communications in continuous variable quantum cryptography. Thanks to this new approach, two honest users can achieve a non-trivial security enhancement as long as the Gaussian interactions of an ...
