The Role of Cryptography in Digital Forensics Investigations
type: item
description: Cryptography plays a critical role in modern digital forensics investigations by ensuring the integrity, confidentiality, and authenticity of digital evidence. As cybercrimes and digital incidents become more complex, cryptographic techniques assist forensic experts in securely capturing, storing, and analyzing data while maintaining legal admissibility. This article explores how cryptography underpins forensic processes including data encryption, hashing, digital signatures, and secure communications. The integration of cryptographic tools improves the reliability of forensic outcomes, aids in evidence verification, and mitigates risks related to data tampering. Challenges related to encryption evasion and cryptographic obfuscation are also discussed, alongside future trends in forensic cryptography.

Securing Cryptographic Algorithms against Side-Channel Attacks
type: item
description: Side-channel attacks (SCAs) represent a significant threat to the security of cryptographic algorithms by exploiting physical leakages such as timing, power consumption, electromagnetic emanations, and fault injection to extract secret keys. This paper presents an overview of common side-channel attacks and explores state-of-the-art countermeasures aimed at securing cryptographic implementations. We discuss algorithmic techniques, hardware-based protections, and software-level mitigations. A comparative analysis of these techniques highlights their effectiveness, overheads, and applicability in different scenarios. The paper also outlines future research directions in developing robust, efficient, and scalable defenses against evolving side-channel threats.

Blockchain for Securing Digital Certificates and Cryptographic Keys
type: item
description: Digital certificates and cryptographic keys are foundational elements in establishing secure communications and identity verification on the internet. Traditional Public Key Infrastructure (PKI) systems, while effective, face challenges such as centralized trust models, vulnerability to single points of failure, and susceptibility to certificate fraud and key compromise. Blockchain technology offers a decentralized, tamper-resistant ledger system that can revolutionize the management and security of digital certificates and cryptographic keys. This paper explores the application of blockchain for enhancing the security, transparency, and trustworthiness of digital certificates and cryptographic key management. We review blockchain-based frameworks, compare them with conventional PKI approaches, and highlight the benefits and limitations of adopting blockchain for these security assets.
