Nonrepudiation is a security principle that ensures that a sender cannot deny sending a message nor can the recipient deny receiving the message. This principle is achieved through techniques like digital signatures or other forms of cryptographic verification. Authentication relates to ensuring that the person or entity accessing a system or resource is who they claim to be, availability refers to ensuring that resources are accessible and usable when needed, and integrity refers to the assurance that data has not been tampered with or corrupted.
