Nilufar Yasmin, Richa Gupta · 2022 8th International Conference on Signal Processing and Communication (ICSC) · 2022
Secure lightweight algorithms have lately been proving their benefits and applications in resource-constrained environments. 3-D printers in a distributed network need security approval for their authentic and secure utilization. NIST round 2 algorithm GIFT-COFB and its primitive algorithm GIFT have been tested for their performance for STL files used in 3-D printers. GIFT-COFB is an Authenticated Encryption with Associated Data (AEAD) algorithm, an underlying scheme for which is the GIFT-128 lightweight block cipher. We analyze the power consumed, energy consumed and time taken by the algorithm for the encryption and decryption of a particular STL file. Then a comparison of state-of-the-art parameters of GIFT-COFB and GIFT is carried out to show the improvements we achieved by using the COFB lightweight AEAD operating mode. Analysis results show its worth in providing security to STL files. For further improvement in the system, signal processing can be applied.
