 **Confidentiality** in cryptography aims to ensure that information is kept secret from unauthorized parties—only the intended recipient(s) can access and understand the message, while anyone else—even if they intercept it—cannot make sense of it. This is typically achieved through **encryption**, which converts readable data (**plaintext**) into **ciphertext** that can only be decrypted by authorized parties with the correct cryptographic key; a widely used example is the **Advanced Encryption Standard (AES)**, standardized by the U.S. National Institute of Standards and Technology [[FIPS-197]].
 
-Maintaining confidentiality also requires proper key management and access control. Secure key management ensures that cryptographic keys are safely generated, stored, and distributed, while access control mechanisms restrict information to only those with permission, preventing unauthorized use or disclosure (see [Section 4.2] (#key-management) for more details on key management).
