Tanda tangan Digital Menggunakan Algoritme Keccak dan RSA
Just like conventional signatures, digital signatures can be used to prove the authenticity of a document in digital form. In addition, digital signatures can also be used to prove the validity of the author of the document, so that the author of the ...

A Tale of Snakes and Horses: Amplifying Correlation Power Analysis on Quadratic Maps
We study the success probabilities of two variants of Correlation Power Analysis (CPA) to retrieve multiple secret bits. The target is a permutation-based symmetric cryptographic construction with a quadratic map as an S-box. More precisely, we focus on

Contemporary distributed ledgers face an inherent trilemma when attempting to simultaneously optimize three critical properties: transaction throughput (measured in transactions per second [TPS]), network security, and node decentralization. Current decentralized storage platforms such as Filecoin encounter constraints in managing peak transaction ...

Design and Development of a Blockchain‐Enabled Decentralized Framework for Academic Microcredentials
Traditional higher education faces significant challenges, including rising costs, inflexibility, and a disconnect from workforce demands, while current credentialing systems are often centralized and vulnerable to fraud. Microcredentials have emerged as a solution, yet they lack integration into formal degree pathways and face issues with recognition ...

Applying Grover's Algorithm to Hash Functions: A Software Perspective
Quantum software frameworks provide software engineers with the tools to study quantum algorithms as applied to practical problems. We implement classical hash functions MD5, SHA-1, SHA-2, and SHA-3 as quantum oracles to study the computational resource ...

Enhancing Security and Transparency in Satellite Data Transactions Using Ethereum‐Based Blockchain
This study presents an Ethereum‐based framework for securing satellite data transactions using ERC1155 tokenization, Proof of Authority consensus, and Threshold Cryptography. The system achieves low latency, high throughput, and significantly reduced gas costs while providing strong resistance against MITM, Sybil, and reentrancy attacks.

Conditional Cube Attack on Round-Reduced ASCON
This paper evaluates the secure level of authenticated encryption Ascon against cube-like method. Ascon submitted by Dobraunig et al. is one of 16 survivors of the 3rd round CAESAR competition. The cube-like method is first used by Dinur et al.

Threshold Implementations in Software: Micro-architectural Leakages in Algorithms
This paper provides necessary properties to algorithmically secure firstorder maskings in scalar micro-architectures. The security notions of threshold implementations are adapted following micro-processor leakage effects which are known to the ...
