| | | | | Digital Signatures The digital signature (sometimes called an electronic signature) isn't a literal digitalized signature. In layman's terms, it is a procedure that guarantees the integrity and the authenticity of digital documents and messages. The name of a digital signature comes from the analogy with the handwritten signature of a paper document. Everyone knows that there is a lot of paperwork in the world of business. And, where there is paperwork, there is a lot of validation, approvals, etc. | |

| | | | | One weird hobby of mine is reasonable properties of cryptographic schemes that nobody promised they do or don't have. Whether that's invisible salamanders or binding through shared secrets, anything that isn't just boring IND-CCA2 or existential unforgeability is just delightful material to construct vulnerabilities with. Normally, with a signature scheme, you have the public key... | |

| | | [AI summary] This article discusses the potential threat that quantum computers pose to current cryptographic protocols and outlines strategies for securing communications against such threats. It explains how quantum computing can break existing asymmetric encryption algorithms, like those used in TLS, and highlights the need for post-quantum cryptographic algorithms (PQ). The article details the implementation of these algorithms in existing protocols, the importance of key establishment, and the challenges of transitioning to post-quantum authentication. It concludes by emphasizing the urgency of preparing for a post-quantum future and the role of technologies like automatic certificate issuance in facilitating this transition. | ||
