The discussion revolves around the differences between encrypting electrical signals and optical signals, specifically addressing the processes of encryption in both domains and the implications of each approach. Participants explore theoretical and practical aspects of signal encryption techniques, including symmetric and asymmetric methods.
Participants do not reach a consensus on whether encrypting in the optical domain is advantageous compared to electrical encryption. Multiple competing views remain regarding the practicality and effectiveness of each approach.
Limitations include the lack of clarity on the specific conditions under which optical encryption may be preferred, as well as unresolved questions about the integration of compression techniques with optical encryption methods.
Researchers and practitioners in the fields of signal processing, telecommunications, and cryptography may find this discussion relevant, particularly those interested in the comparative analysis of encryption techniques across different signal domains.
What are your thoughts? And how do you propose to encrypt the optical signal?Fiona Rozario said:What is the difference between encrypting an electrical signal and converting it to optics; & converting the signal to optics and then encrypting it? (Any of the symmetric or asymmetric encryption techniques).
