  • Cryptography:  Key Exchange

    Key exchange is a fundamental concept in cryptography that allows two parties to securely exchange keys over an insecure communication channel. These keys are used for encrypting and decrypting messages, ensuring that only the intended recipient can access the information. Key exchange protocols form the backbone of secure communication in systems like online banking, email…

  • Cryptography: Public Key Infrastructure

    Public Key Infrastructure (PKI) is a framework used to secure communications and manage digital certificates in a network. It involves the use of both public and private keys to ensure data confidentiality, integrity, and authentication. PKI plays a critical role in securing sensitive data, enabling secure online transactions, and ensuring identity verification in online communications.…

  • TLS 1.3 (Transport Layer Security)

    TLS 1.3 (Transport Layer Security): An In-Depth Analysis Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network. TLS 1.3 is the latest version of the protocol, significantly improving both security and performance compared to its predecessors. It was officially published by the IETF (Internet Engineering Task Force)…

  • TLS 1.2 ( Transport Layer Security)

    TLS 1.2 (Transport Layer Security): A Deep Dive into Its Architecture and Mechanisms Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication across computer networks, such as the Internet. TLS 1.2, an important version of the TLS protocol, was introduced in 2008 and became the de facto standard for securing data…
