A communication methodology that ensures message privacy, authenticity, and integrity through cryptographic protocols and security measures.

Secure Messaging

Secure messaging encompasses the technologies, protocols, and practices that enable confidential and authenticated communication between parties across potentially insecure networks.

Core Principles

The fundamental pillars of secure messaging include:

End-to-End Encryption - Ensuring only intended recipients can read messages
Message Authentication - Verifying the sender's identity
Forward Secrecy - Protecting past communications if keys are compromised
Metadata Protection - Minimizing exposure of communication patterns

Technical Implementation

Secure messaging systems typically employ several key technologies:

Cryptographic Protocols

Public Key Cryptography for key exchange
Symmetric Encryption for message content
Digital Signatures for authentication
Hash Functions for message integrity
