TLS 1.3

Definition ∞ TLS 1.3, or Transport Layer Security version 1.3, is the latest cryptographic protocol designed to provide secure communication over a computer network. It ensures data privacy and integrity between two communicating applications, such as a web browser and a server. This version significantly improves upon its predecessors by enhancing security, simplifying the handshake process, and boosting performance. It is a foundational component for securing internet traffic and digital transactions.
Context ∞ The widespread adoption of TLS 1.3 is critical for enhancing internet security and protecting sensitive data, including cryptocurrency transactions and user interactions with digital asset platforms. Discussions frequently center on its role in mitigating various cyber threats, such as man-in-the-middle attacks and data breaches. Continued implementation across web services and blockchain infrastructure remains a key focus for maintaining robust digital security standards.
