In the realm of cybersecurity, public-key management plays a crucial role in establishing trust, confidentiality, and authenticity. One of the most fundamental challenges in using public-key cryptography is providing assurance that a public key genuinely belongs to the intended entity.…

As cybersecurity continues to evolve, encryption methods are adapting to meet new challenges and demands. One of the most groundbreaking developments in this area is Attribute-Based Encryption (ABE), which expands upon the concept of Identity-Based Encryption (IBE) to provide more…

Identity-Based Encryption (IBE) is a cryptographic system that simplifies key management by associating a user’s identity with their public key. In Chapter 11, Section 11.4.2 of Martin’s Public-key Management book, the concept of IBE is explored as a powerful alternative…

Public-key infrastructure (PKI) relies heavily on cryptographic keys to ensure secure communication. One concept that helps to manage and validate these keys is the Web of Trust (WoT). This decentralized approach, outlined in Chapter 11, Section 11.4 of Martin’s work…

Public Key Infrastructure (PKI) plays a pivotal role in ensuring secure communication over the internet. However, as highlighted by Ellison and Schneier in their seminal paper, “Ten Risks of PKI: What You’re Not Being Told About Public Key Infrastructure” (2000),…
