A note on the security of the hHB protocol [PDF]
arXiv, 2015 We propose a polynomial-time attack on the hHB protocol, showing that the protocol does not attain the claimed security. Our attack is based on the GRS attack.

Full Restoration of Visual Encrypted Color Images [PDF]
arXiv, 2011 While strictly black and white images have been the basis for visual cryptography, there has been a lack of an easily implemented format for colour images. This paper establishes a simple, yet secure way of implementing visual cryptography with colour, assuming a binary data representation.

Virtual Entanglement and Reconciliation Protocols for Quantum Cryptography with Continuous Variables
, 2003 We discuss quantum key distribution protocols using quantum continuous variables. We show that such protocols can be made secure against individual gaussian attacks regardless the transmission of the optical line between Alice and Bob.

A tight security reduction in the quantum random oracle model for code-based signature schemes [PDF]
, 2017 Quantum secure signature schemes have a lot of attention recently, in particular because of the NIST call to standardize quantum safe cryptography. However, only few signature schemes can have concrete quantum security because of technical difficulties ...
