Optical cryptography
WebNov 11, 2024 · Optical networks are vulnerable to several types of security breaches aiming to disrupt the service or gain unauthorized access to the system. The evolution of programmable and flexible node architecture software has resulted in new security vulnerabilities that need to be considered during network design and operation. Weboptical layer, to increase the degree of confidentiality against all kind of attacks. Data transmitted is divided in sequences of m bits and encoded with an alphabet with at least M = 2m determinations, that correspond to optical codes; the secret key is not the optical code itself, but the correspondence between an optical code and a bit sequence.
