Abstract

This study integrates Zero Trust Architecture (ZTA) and Blockchain to strengthen cloud computing security. In the digital era, cloud computing has become a mainstream technology for data storage and processing globally. However, traditional perimeter-based security models have proven ineffective in dealing with modern threats, such as insider threats increasing by 60% and ransomware attacks on major cloud computing providers in 2022 resulting in billions of dollars in losses, highlighting the weaknesses of existing security models. Zero Trust Architecture (ZTA) offers a solution with a granular access control approach and layered authentication, but its implementation still faces challenges in efficiency and scalability, Blockchain, with its decentralized technology and immutable records, improves data transparency and integrity, but its use is often constrained by high energy consumption and latency. This study aims to explore between ZTA and Blockchain as innovative solutions to improve cloud security. By combining ZTA-based access control and Blockchain transparency, this study develops a security model that is resilient to both internal and external threats. Simulations show that ZTA and Blockchain integrity can reduce insider threats by 35% and increase data audit efficiency by 20%. This approach not only offers stronger protection but also provides an adaptive and transparent system for rapidly evolving cloud infrastructure.

Abstract

Art exhibitions as a means of displaying creative works require innovation in the interaction between visitors to artworks. Currently, the use of augmented reality (AR) in art exhibitions is increasingly relevant and attracts attention as an interactive medium. However, challenges in its implementation still exist, including the lack of visitor engagement and limited physical space. The proposed solution is to use the marker-based tracking method in AR, which allows the integration of artworks with the environment through visual markers. This method allows visitors to interact directly with artworks through their mobile devices. In this context, the marker-based tracking method uses physical and visual markers, such as images or certain objects, to trigger AR elements. Visitors can access additional content, such as information about the artwork, multimedia interactions, or dynamic visualizations, by pointing their devices at the specified markers. This creates a new dimension in art, allowing visitors to interact directly with artworks through additional digital layers. The result is increased visitor interaction and participation in art exhibitions, resulting in a more immersive and dynamic experience. This system is expected to broaden the appreciation of art, encourage discussion, and enrich the visitor experience. The main goal is to enrich the visitor experience in understanding, appreciating, and enjoying artworks through interactive and innovative technology. Thus, the use of AR in art exhibitions with the marker-based tracking method not only creates a creative and immersive experience, but also opens up new potential in connecting art and technology to create a richer and more memorable experience. The results achieved from this study are in the form of providing a deeper experience to visitors in a painting art exhibition.

Abstract

Cryptography is a field that is really needed in the current era of globalization where security and confidentiality of information are very difficult to maintain considering wide and open communication access. Cryptography currently has a variety of methods and techniques which are divided into two categories, namely symmetric cryptography and asymmetric cryptography where their use depends on needs and conditions. The Merkle Hellman Knapsack method is an asymmetric cryptography method that uses a public key and a private key so that tapping and cracking becomes more difficult due to the use of different keys both during encryption and during decryption. Application development using the Merkle Hellman Knapsack method generates public keys and private keys using super increasing and inverse modulo series values, making the cryptanalysis process more difficult. The system developed is able to provide an alternative in securing text data.
