Encryption is the process of transforming information into a coded format to prevent unauthorized access, ensuring that only intended recipients can read or process the data. It is a cornerstone of data security, privacy, and modern communication systems. 🔑 Core Principles Encryption operates on the principle of mathematical transformation, where plaintext is converted into ciphertext […]
Cryptography is the science and engineering of securing communication through mathematical techniques that ensure confidentiality, integrity, authentication, and non-repudiation. At its core, cryptography transforms readable information (plaintext) into an unintelligible form (ciphertext) using an algorithm and a key, such that only authorized parties can reverse the transformation. It is a discipline situated at the intersection
Secure communication refers to the transmission of information between parties in a manner that prevents unauthorized access, alteration, or interception. Its objective is to ensure that messages remain confidential, authentic, and intact during transmission across potentially hostile environments such as public networks. In modern systems, secure communication relies on cryptographic protocols, authentication mechanisms, and network
