High Security Optical Encryption based on Sweeping Computational Ghost Imaging

Abstract A method for the optical data encryption and decryption based on the sweeping computational ghost imaging is proposed. This method is governed on reconstructing the ghost imaging by one-by-one sweeping of rows or columns of the random generated matrices. Proposed encryption in this paper is deﬁned by these sweeping row and column matrices and basic mathematical operators between them. Introduced encryption can be employed as symmetric and asymmetric encryptions. In the symmetric system, cross-operator and the row and column matrices were assumed as private keys, deﬁning the four basic operators as decryption keys. Whereas, in the asymmetric system, permutation of three possible cases was considered as private keys, leaving cross-operator and row and column selection sequence as public keys. The number of pixel changing Rate (NPCR) as a parameter that evaluates the strength of image encryption versus differential attacks was calculated for each case which show high security data transfer to the user. In the asymmetric systems, even with eavesdropping 50% of data, no useful information was obtained from the image or data. In the symmetric systems, with eavesdropping 100% of data, no useful information was obtained by multiple attacking the encrypted data. Offered high security along with achievable high speeds and compact data packages classify sweeping computational ghost imaging among the best applicable methods for optical data encryption.

AbstractAs deep neural network (DNN) models grow ever-larger, they can achieve higher accuracy and solve more complex problems. This trend has been enabled by an increase in available compute power; however, efforts to continue to scale electronic processors are impeded by the costs of communication, thermal management, power delivery and clocking. To improve scalability, we propose a digital optical neural network (DONN) with intralayer optical interconnects and reconfigurable input values. The path-length-independence of optical energy consumption enables information locality between a transmitter and a large number of arbitrarily arranged receivers, which allows greater flexibility in architecture design to circumvent scaling limitations. In a proof-of-concept experiment, we demonstrate optical multicast in the classification of 500 MNIST images with a 3-layer, fully-connected network. We also analyze the energy consumption of the DONN and find that digital optical data transfer is beneficial over electronics when the spacing of computational units is on the order of $$>10\,\upmu $$ > 10 μ m.

High Speed Data

ABSTRACTThe integration of optical interconnects in printed circuit boards (PCB) is a rapidly growing field worldwide due to a continuously increasing need for high-speed data transfer. There are any concepts discussed, among which are the integration of optical fibers or the generation of waveguides by UV lithography, embossing, or direct laser writing. The devices presented so far require many different materials and process steps, but particularly also highly-sophisticated assembly steps in order to couple the optoelectronic elements to the generated waveguides. In order to overcome these restrictions, an innovative approach is presented which allows the embedding of optoelectronic components and the generation of optical waveguides in only one optical material. This material is an inorganic-organic hybrid polymer, in which the waveguides are processed by two-photon absorption (TPA) processes, initiated by ultra-short laser pulses. In particular, due to this integration and the possibility ofin situpositioning the optical waveguides with respect to the optoelectronic components by the TPA process, no complex packaging or assembly is necessary. Thus, the number of necessary processing steps is significantly reduced, which also contributes to the saving of resources such as energy or solvents. The material properties and the underlying processes will be discussed with respect to optical data transfer in PCBs.

Encryption And Decryption

In this paper two methods are used, namely the vigenere cipher method and the RSA method. The vigenere cipher method is an example of a symmetric algorithm, while RSA is an example of an asymmetric algorithm. The combination of these two methods is called hybrid cryptography which has the advantage in terms of speed during the encryption process. Each process, which is encryption and decryption, is carried out twice, so that security can be ensured. In the process of forming the key used the RSA method. In the encryption process using public keys that have been generated before when the key is formed. This public key is used in sending data to the recipient of a secret message where this key is used for the data encryption process. The Secret key is kept and will be used during the decryption process. There is a system architecture that describes how clients and servers communicate with each other over the internet using the TCP protocol where the client here is an IoT device and the server is a server.
