UGM’s Center for Cryptography and Cyber Security Studies Holds Third Reading Group Spotlighting E-Voting Scheme Using Double-Trapdoor

Yogyakarta, February 9, 2024 – In an ongoing effort to enhance understanding and expertise in the fields of cryptography and cyber security, the Center for Cryptography and Cyber Security Studies (C3R) at the Faculty of Mathematics and Natural Sciences (FMIPA) Universitas Gadjah Mada (UGM) successfully organized its third reading group session. This activity took place on Friday, February 9, 2024, at 09:00 AM, via the Zoom Meeting platform, providing an opportunity for students and academic communities interested in cryptography to delve into current issues in the sector. This routine activity, facilitated by students under the guidance of faculty members, aims to nurture proficient young cryptographers for the future.

Annisa Dini Handayani, a PhD student in mathematics at UGM who is also a lecturer at Politeknik Siber dan Sandi Negara, led the discussion of a paper in this session. With her expertise, Annisa dissected the paper titled “New Receipt-Free Voting Scheme Using Double-Trapdoor Commitment,” a research article published in the Information Sciences journal in 2011 by prominent researchers in the field such as Xiaofeng Chen, Qianhong Wu, Fangguo Zhang, Haibo Tian, Baodian Wei, Byoungcheon Lee, Hyunrok Lee, and Kwangjo Kim.

The paper delves into the concept of double-trapdoor commitment scheme, which is considered to have higher security compared to single-trapdoor commitment schemes. This advantage stems from the requirement of obtaining two secret values to break the entire scheme, making it more resistant to security penetration attempts. Furthermore, this concept holds great potential in e-voting applications, constructing zero knowledge proof schemes, and electronic auctions (e-auction).

The session also presented a new, efficient voting scheme that does not require registration parameter committees or voting booths, making it a practical solution for large-scale elections. Utilizing blind signature-based double-trapdoor commitment, this scheme offers more efficient zero knowledge proof and enables the attainment of desired security properties with weaker assumptions.

UGM’s Center for Cryptography and Cyber Security Studies invites all students, researchers, and practitioners interested in engaging in in-depth discussions on current issues in cryptography. This initiative not only supports the enhancement of understanding and knowledge among participants but also contributes to Sustainable Development Goals (SDGs) number 9 on Industry, Innovation, and Infrastructure, and number 11 on Sustainable Cities and Communities.

As a research institution under the auspices of FMIPA UGM, C3R is committed to continuously contribute to the improvement of cryptography and cyber security through research activities, training, and innovation development.
