Transport Layer Security (TLS)

A cryptographic protocol used to secure communications over the internet.

Understanding Transport Layer Security (TLS)

Transport Layer Security (TLS) is a cryptographic protocol designed to secure communications over a computer network. It ensures data confidentiality, integrity, and authentication between web servers, applications, and clients. TLS is the successor to Secure Sockets Layer (SSL) and is widely used in internet security.

How TLS Works

Handshake Process

Establishes a secure session between a client and a server.
Negotiates encryption algorithms and exchanges cryptographic keys.

Data Encryption

Encrypts data using symmetric cryptography to protect it from eavesdropping.

Authentication

Uses digital certificates and public key infrastructure (PKI) to verify server and client identities.

Integrity Check

Employs hashing algorithms to detect any tampering during data transmission.

Future of TLS

Post-Quantum Cryptography – Developing TLS algorithms resistant to quantum computing threats.
Zero Trust Security Models – Integrating TLS with evolving cybersecurity frameworks.
Enhanced AI-Driven Security – Using artificial intelligence to detect and mitigate TLS vulnerabilities.

TLS is a critical component of internet security, ensuring safe and private communications across various digital platforms.
