Fragment-synthesis-based multiparty cryptographic key distribution over a public network
This addresses secure key distribution for optical communication systems, but appears incremental as it builds on computational ghost imaging with a modified authentication approach.
The authors tackled the problem of secure optical communication by proposing a fragment-synthesis-based interactive protocol for multi-party cryptographic key distribution over public networks, which enables self-authentication through an intermediary.
A secure optical communication requires both high transmission efficiency and high authentication performance, while existing cryptographic key distribution protocols based on ghost imaging have many shortcomings. Here, based on computational ghost imaging, we propose an interactive protocol that enables multi-party cryptographic key distribution over a public network and self-authentication by setting an intermediary that shares partial roles of the server. This fragment-synthesis-based authentication method may facilitate the remote distribution of cryptographic keys.
