Prof. Suryadi Officially Becomes Professor of FMIPA UI, Emphasizes the Importance of Cybersecurity in the Digital Era

The Faculty of Mathematics and Natural Sciences (FMIPA) of the University of Indonesia (UI) has added to its list of Professors with the inauguration of Prof. Dr. Drs. Suryadi, M.T. as a permanent Professor in the field of Data Security Science. The inauguration took place on Wednesday (12/2) at the Convention Hall, UI Depok Campus, and was led by the UI Chancellor, Prof. Dr. Ir. Heri Hermansyah, S.T., M.Eng., IPU.

In his inaugural speech entitled "Mathematical Advocacy in Cryptographic Systems and Intruder Detection Systems", Prof. Suryadi discussed various important issues related to data security in the current digital era. He revealed that the industrial revolution 4.0 has brought major changes in the way information is produced and distributed through the adoption of digital technology, artificial intelligence, and increasingly widespread connectivity.

"The digital transformation that brings all data to be digitally based and connected via the internet of things (IoT) raises major challenges in terms of data security. Cybersecurity is a major issue that must be our collective concern," said Prof. Suryadi.

Furthermore, he emphasized the importance of managing data and information security, which is now not only a support, but also a primary resource that has a value far greater than oil. "Data and information must be maintained and protected properly so that it is not lost or even detrimental," he added.

In his speech, Prof. Suryadi also expressed his concerns regarding the high threat of cyber attacks in Indonesia. Based on data from the National Cyber ​​and Crypto Agency (BSSN), 158 cyber attacks were recorded per second during the period from January to June 2024. He appealed to all parties, both individuals, organizations, agencies, and companies, to be more vigilant against this threat.

In addition, Prof. Suryadi highlighted the phenomenon of image manipulation or deep fakedeep fake, which is widely used for negative purposes on social media. For this reason, he suggested the implementation of a dynamic intruder detection system and data security using cryptography and steganography techniques.

One of the breakthroughs developed by Prof. Suryadi is a chaos function-based cryptography technique which is claimed to provide stronger protection for digital data. He also emphasized the importance of strengthening the national cybersecurity system in accordance with Presidential Regulation Number 47 of 2023 concerning the National Cybersecurity Strategy (SKSN).

Prof. Suryadi added that this effort is in line with the achievement of the Sustainable Development Goals (SDGs), especially SDG number 9 which relates to industrial and infrastructure development, and SDG number 11 which aims to create a safe and sustainable city.

"The research we developed uses two encryption approaches, namely keystream cipher and block cipher, which can improve data protection at various levels," he explained.

In the future, the biggest challenge faced is how to implement this cryptographic algorithm into a physical device such as an integrated circuit (IC) through the design of a Field Programmable Gate Array (FPGA). Prof. Suryadi also encouraged the need for pentahelix cooperation between academics, government, industry, society, and the media to support the development of the national cryptography industry.

With this inauguration, Prof. Suryadi hopes that research and innovation in the field of cryptography can further support the creation of a safer, more sustainable, and more competitive society at the global level.

Suryadi completed his undergraduate education at FMIPA UI in 1990. Then in 1998, he completed his master's studies at the Faculty of Industrial Technology, Bandung Institute of Technology (ITB). Then, he returned to UI and successfully obtained a doctorate from the Faculty of Engineering (FT), in 2013.

The inauguration procession was also attended by Professor of the Defense University, Deputy Head of the National Research and Innovation Agency (BRIN) Vice Admiral TNI (P). Prof. Dr. Ir. Amarulla Octavian, ST, MSc., DESD, IPU, ASEAN.Eng .; Professor of Police Science Studies at the Police Science College (STIK) PTIK, Head of the Indonesian Police Education and Training Institute, Commissioner General.
