🔐 Encryption Standards: Ensuring Data Confidentiality and Integrity Encryption is a foundational technology in cybersecurity, used to protect data confidentiality, verify authenticity, and ensure data integrity both at rest and in transit . Various standards define how encryption algorithms are implemented, tested, and used. 🧠 Types of Encryption Type Description Use Cases Symmetric Encryption Same key used for encryption and decryption Disk encryption, file encryption Asymmetric Encryption Uses a public key (encrypt) and private key (decrypt) Secure key exchange, digital signatures Hashing One-way transformation, no decryption possible Password storage, integrity checks 📜 Common Encryption Standards 1. AES (Advanced Encryption Standard) Type: Symmetric block cipher Key sizes: 128, 192, 256 bits Block size: 128 bits Use: Encrypting data at rest and in transit Status: NIST standard (FIPS 197), widely used worldwide Strength: Considered very secure and...
