Abstract

In the last few years, several studies addressed the problem of data security in Mifare Classic. One of its weaknesses is the low random number quality. This causes SAT solver attacks to have lower complexity. In order to strengthen Crypto-1 against SAT solver attacks, a modification of the feedback function with better cryptographic properties is proposed. It applies a primitive polynomial companion matrix. SAT solvers cannot directly attack the feedback shift register that uses the modified Boolean feedback function, the register has to be split into smaller groups. Experimental testing showed that the amount of memory and CPU time needed were highest when attacking the modified Crypto-1 using the modified feedback function and the original filter function. In addition, another modified Crypto-1, using the modified feedback function and a modified filter function, had the lowest percentage of revealed variables. It can be concluded that the security strength and performance of the modified Crypto-1 using the modified feedback function and the modified filter function are better than those of the original Crypto-1.

Abstract

The inefficiency of traditional administrative processes highlights the need for innovative digital solutions. This study aims to evaluate and compare the performance of blockchain-based and non-blockchain-based business licensing systems to determine which approach offers better efficiency and security. The blockchain system was developed using Hyperledger Fabric with IPFS for data storage, while the non-blockchain system utilized Node.js with the Express.JS framework and MinIO for storage. Testing involved document upload and retrieval operations based on User ID and Document ID. Results indicate that while the blockchain system offers enhanced data integrity and security, it suffers from significantly slower performance, especially in document upload operations. The non-blockchain system demonstrated faster and more consistent response times, suggesting that in contexts where speed is crucial, a non-blockchain approach may be more suitable, despite the security trade-offs.

Abstract

Perkembangan teknologi memungkinkan smart devices untuk saling terhubung melalui Internet of Things (IoT), membuka berbagai peluang aplikasi dalam kehidupan seharihari. Namun, hal ini juga menimbulkan kekhawatiran terhadap keamanan data dan privasi, terutama karena perangkat IoT memiliki keterbatasan daya komputasi, memori, dan daya baterai. Untuk mengatasi ini, kriptografi ringan seperti New Lightweight Cryptographic Algorithm (NLCA) menjadi penting. NLCA menjanjikan kinerja lebih cepat dibandingkan dengan algoritma kriptografi ringan lainnya. Namun, belum diuji pada perangkat berdaya komputasi rendah. Dalam penelitian ini, data dengan panjang 32, 200, 400, dan 800 karakter diuji menggunakan simulator perangkat ESP32. Pada data sepanjang 200 karakter, NLCA memerlukan waktu 66,645 detik, sedangkan AES hanya membutuhkan 1,682 detik. Hasil penelitian menunjukkan bahwa NLCA memiliki rata-rata waktu eksekusi yang lebih lama dibandingkan dengan AES, dengan fungsi F menjadi faktor utama yang memperpanjang waktu eksekusi. Kata kunci— Kriptografi ringan, Internet of Things

Abstract

The digital transformation in vocational education demands institutions to optimize the use of Learning Management Systems (LMS) as effective platforms for hybrid learning. Politeknik Penerbangan Indonesia Curug has adopted LMS, yet its usage remains limited to administrative functions and lacks deeper pedagogical integration. This community service initiative aimed to enhance the digital competencies of teaching staff through intensive LMS training based on the Direct Instruction with Guided Practice method. The program's partner consisted of lecturers from PPI Curug. The training was conducted in stages, including material delivery via Telkom University's e-learning platform, interactive offline workshops, guided hands-on sessions, evaluation through pre- and post-tests, and final feedback. Results showed an average score increase of 7.47 points, with 93.3% of participants achieving post-test scores within the 91–100 range. This effort aligns with Indonesia’s Asta Cita vision, particularly Asta Cita 4, in strengthening human resources, science, and technology towards realizing Indonesia Emas 2045. It also supports the Sustainable Development Goals (SDG) point 4 on Quality Education through the digitalization of learning processes. Consequently, this activity reflects the strong commitment of Telkom University’s academic community in upholding the values of HEI (Harmony, Excellence, Integrity), which derive from the AKHLAK BUMN core values, serving as the foundation of institutional culture and service. Through structured collaboration, this program contributes to building an innovative and sustainable digital education ecosystem.

Abstract

The Internet of Things is a complex system that is widely used in many ways to advance human life. As a result, Internet of Things (IoT) has many security vulnerabilities and requires an authentication system to protect user data. Selecting the authentication type that suits your needs is critical to achieving excellent performance on your Internet of Things (IoT) devices with relatively minimal specifications. Due to this situation, Elliptic Curve Cryptography (ECC) algorithm is one of the recommended algorithms which consumes less resources in the process. This study aims to test and compare the Fiat-Shamir based Elliptic Curve Cryptography (ECC) and Elliptic Curve Diffie-Hellman based Hash Message Authentication Code (ECDH-HMAC) authentication algorithms. Parameters for this test are computation time, delay, program storage, and communication cost of the authentication algorithm. The experimental results show that the Elliptic Curve Diffie-Hellman based Hash Message Authentication Code (ECDH-HMAC) algorithm has the lowest computational time, delay, and program storage usage, and the Fiat-Shamir based Elliptic Curve Cryptography (ECC) algorithm has the lowest communication cost value.

Abstract

Inventions solving problems through the incorporation of technology and social impacts to facilitate human life can be defined as the Internet of Things (IoT). Security and privacy are challenges in various Internet of Things applications given the rapid growth of IoT devices. Meanwhile, IoT devices still do not have sufficient communication security. Communication systems on IoT devices require cryptographic to maintain the security of their communications. The appropriate algorithm to be implemented on IoT devices should be the smallest and fastest lightweight cryptographic algorithm or commonly called Lightweight Cryptography because IoT devices have limited memory and computing power. In this study, the proposed algorithm to be implemented in Long Range or LoRa-based IoT devices is the Simon-Speck, Simeck, and Skinny encryption algorithm. This study discusses the implementation of the Simon-Speck, Simeck, and Skinny algorithms on Long Range-based IoT devices. The parameters compared are the computation time of the encryption and decryption process and the avalanche effect value. In the encryption and decryption process, the Speck algorithm has the fastest computation time. Meanwhile, the highest avalanche effect value is obtained by the Skinny algorithm, which is 50.34%.

Abstract

This paper investigates the application of a three dimensional Bloom Filter (3DBF) to accomplish a secure and efficient accounts storage system by exploiting hashes of usernames and their corresponding passwords. We conducted numerical experiments and mathematical analysis to study the efficiency level of several 3DBF schemes. Our experimental results and analysis show that the level of occupancy for 3DBF is positively correlated to the value of its false positive rate, viz., if the occupancy level increases then so does the value of the false positive rate. Moreover, we also derive a formula for determining the minimum number of bits for storing some data in a 3DBF scheme given the value of its acceptable false positive rate and its occupancy level. We infer that the product of the dimensional parameter of a 3DBF scheme is inversely proportional to the false positive rate and occupancy level used in the scheme.
