The generation of encryption secret keys with a high level of security is crucial to ensure secure enduring data storage and is a challenging topic of investigation. We show that the use of nano-objects and optical response permits us to produce a complex optical tomography map, which can be used as a pseudorandom generator that satisfies the basic requirements for encryption based on the secret key.
