Double-Lock Strategy Applied to Optical Spectral Phase and Delay Encoding
(Ieee, 2017-01-01)
Physical layer encryption (PLE) is a promising technology for increasing the security of communication networks. An important goal of PLE is to establish a mechanism that allows authorized users to understand cyphered ...

Optical encryption and QR codes: Secure and noise-free information retrieval
(Optical Society Of America, 2013-03)
We introduce for the first time the concept of an information “container” before a standard optical encrypting procedure. The “container” selected is a QR code which offers the main advantage of being tolerant to pollutant ...
Experimental scrambling and noise reduction applied to the optical encryption of QR codes
(Optical Society Of America, 2014-08)
In this contribution, we implement two techniques to reinforce optical encryption, which we restrict in particular to the QR codes, but could be applied in a general encoding situation. To our knowledge, we present the ...
Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
Experimental analysis of a joint free space cryptosystem
(Elsevier, 2016-08)
In this paper, we analyze a joint free space cryptosystem scheme implemented in an actual laboratory environment. In this encrypting architecture, the object to be encoded and the security key are placed side by side in ...
