The Internet of Things (IoT) is one of the most important phases in computer science and information technology research. Connectivity between IoT devices is predicted to reach 30.90 billion by 2025. Despite having resources such as a standard computer, IoT devices have quite several limitations, such as memory, power, speed, and device area size.
Usually, these IoT devices will use standard cryptographic primitives. One type of cryptographic primitive that is widely used in IoT is the cryptographic hash function, which plays an important role in many information and cyber security applications. So, to produce a hash function that is better and suitable for implementation in an IoT environment with limited resources, a new cryptographic hash function is needed.
This apparently sparked Susila Windarta, a doctoral student in the Department of Electrical Engineering, Faculty of Engineering, Universitas Indonesia (DTE FTUI), to do further research on this through his dissertation entitled “Development of a New Cryptographic Hash Function Based on Sponge Construction for the Internet of Things (IoT)”. This dissertation was presented at the FTUI DTE Doctoral promotion session on Monday (10/7/23).
“The specific aim of this research is actually to design a new permutation algorithm that has good diffusion properties and is resistant to differential and linear cryptanalysis. This permutation algorithm becomes the main component of the new hash function, designs a new hash function that meets the criteria of a good hash function, including resistance to preimage, second preimage, and collision attacks, and performs a hash function robustness test using differential cryptanalysis and linear cryptanalysis,” said Susila.
From this research, Susila has developed a new cryptographic hash function based on sponge construction, namely two new permutations with a good level of security in differential and linear cryptanalysis aspects, namely the Modified-SATURNIN permutation and the WSR permutation, and three new lightweight hash function algorithms, namely ALIT-Hash, TJUILIK-Hash, and WSR-Hash. ALIT-Hash and TIUILIK-Hash are based on the SATURNIN block cypher algorithm and a Beetle sponge-based mode of operation.
“Products related to information and cyber security are a contribution to ideas that can later be developed further, including the development of implementations on other hardware devices. This research is also expected to spark research collaboration with research partners to support Excellence and Impact on security and cryptology technology in Indonesia. It is hoped that the achievements of the doctoral programme will continue to increase every year so that in the next 7-8 years FTUI will reach 1,000 doctors,” said the Dean of FTUI, Prof. Dr. Heri Hermansyah, S.T., M.Eng., IPU.
Susila Windarta won a Doctorate with a GPA of 4.00. He is also the 158th Doctor from DTE-FTUI and the 508th Doctor from FTUI. The promotion session was chaired by the Chairman of the Session, Prof. Dr. Heri Hermansyah, S.T., M.Eng., IPU. With the promoter, Prof. Dr-Ing. Ir. Kalamullah Ramli, M.Eng., and Co-Promoter, Dr. Drs. Suryadi, M.T., and the team of examiners, Prof. Dr. Ir. Riri Fitri Sari, M.M., M.Sc.; Prof. Dr. Ir. Anak Agung Putri Ratna, M.Eng.; Dr. Ir. Dodi Sudiana, M.Eng.; Dr. Muhammad Salman, S.T., M.IT; Dr. Ruki Harwahyu, S.T., M.T., M.Sc.; Dr. Bernardi Pranggono, B.Eng., M.DigComms.
The doctoral promotion session which took place in Makara 04 Smart Meeting Room Room 1st Floor of the FTUI Dean Building was also attended by several important guests, namely the Head of the National Cyber and Crypto Agency, Lieutenant General TNI (Purn) Hinsa Siburian, Main Secretary of BSSN, Y.B. Susilo Wibowo, S.E., M.M., Director of National Cyber and Crypto Engineering Polytechnic, First Marshal of TNI R.
