Vulnerability to chosen-plaintext attack of a general optical encryption model with the architecture of scrambling-then-double random phase encoding
Yushu Zhang, Di Xiao, Wenying Wen, Hong Liu · Optics Letters · 2013
We demonstrate a new approach to chosen-plaintext attack on a general encryption model based on scrambling preprocessing operation and double random phase encoding (DRPE). With this attack, an opponent can access both the scrambling key and two random phase keys. We hope that our work motivates further security analysis of the optical encryption scheme combining the scrambling techniques and DRPE.
