GCM-SIV2 is a nonce-based beyond-birthday-bound (BBB)-secure authenticated encryption (AE) mode introduced by Iwata and Minematsu at FSE 2017. However, it is built by combining two instances of GCM-SIV1 and needs eight keys, which increases the costs...
The complexity and isomerization of communication networks have put forth new requirements for cryptographic schemes to ensure the operation of network security protocols. Robust cryptographic schemes have been gradually favored. The robust initializ...
In this paper, we propose a bus-independent hardware (HW)-based approach to secure long protocol data units (PDUs) in Automotive Open System Architecture (AUTOSAR)-based automotive electronic control units (ECUs). Our approach is based on extending p...
In the current context, classic software licensing and protection mechanisms based exclusively on host application checks can be circumvented by patching, emulation and replay attacks in user-controlled environments. This paper presents an adaptive h...
The Enhanced Cipher Block Chaining scheme (eCBC) is an authentication encryption scheme (AE) improved from the CBC encryption scheme. It is shown that eCBC scheme fails to achieve ciphertext integrity (INT-CTXT): the IV is unauthenticated and the tag...
This paper presents high-performance Advanced Vector Extensions 512 (AVX-512) implementations of two Korean standard cryptographic algorithms: the Lightweight Secure Hash (LSH) function and Lightweight Encryption Algorithm–Galois/Counter Mode (...
Industrial Internet of Things (IIoT) deployments increasingly rely on low-cost microcontrollers and single-board computers to stream operational telemetry for monitoring, control, and predictive maintenance, yet the canonical “TLS-to-broker&rdq...
LoRaWAN holds immense potential in smart applications for its low-power, long-range communication capabilities and in-built AES-128 encryption for end-to-end security. However, prior research has identified critical security vulnerabilities, most not...
Persistent security challenges in Industry 4.0 due to the limited resources of IoT devices necessitate innovative solutions. Addressing this, this study introduces the ASCON algorithm for lightweight authenticated encryption with associated data, enh...
Web applications increasingly handle sensitive data in diverse use cases, but conventional encryption implementations apply a uniform level of cryptographic protection to all traffic, regardless of the associated risk. This static approach results in...
This paper presents a secure data sharing platform that organises KR-IBI, KR-IBE, KR-PEKS, and KR-PAEKS into an end-to-end Rust/Tauri workflow for registration, authentication, encrypted upload, searchable retrieval, and authorised decryption. The wo...
Decentralised machine learning requires authenticated transport to secure exchanged model updates. To this end, this study presents a healthcare-focused proof of concept integrating a quantum key distribution (QKD) simulation with HKDF-SHA-256, AES-2...
Quantum computing poses a serious long-term risk to modern cryptographic systems, including the widely used Signal messaging protocol. This research work addresses that risk by integrating ML-KEM-768, a NIST-standardized post-quantum algorithm specif...
Unmanned aerial vehicles (UAVs) have become increasingly popular in recent years and are applied in various fields, from commercial and scientific to military and humanitarian operations. However, their usage presents many challenges, including limit...
Cloud-integrated sensor and Internet of Things (IoT) systems enable scalable data storage, processing, and intelligent monitoring, but their distributed nature exposes network-flow and host-level data to unauthorized access, tampering, and cyberattac...
Cryptographic inventories and runtime detection identify cryptographic use but do not establish implementation conformance or policy satisfaction. We present a deterministic composition linking admitted runtime evidence, provenance closure, exact imp...
With digital assets increasingly comprising a significant portion of personal wealth, the secure management and transfer of digital legacies have emerged as a pressing concern. Secret sharing offers a solution to this problem. However, distributing s...
Big data has significantly transformed data processing and analytics across various domains. However, ensuring security and data confidentiality in distributed platforms such as Hadoop remains a challenging task. Distributed environments face major s...
Structural complexity in a graph-derived representation does not by itself establish cryptographic security. This paper performs a self-cryptanalysis of the authors’ own middle-graph matrix cipher from an earlier version of this manuscript; the...
Secure exchange of electronic health records (EHRs) requires clinical confidentiality, verifiable provenance, patient-controlled authorization, and practical handling of high-resolution medical imaging payloads generated by IoMT digital radiography s...
