Secure Communication Protocols

Secure communication protocols protect data as it travels across networks, ensuring privacy, integrity, and authentication. Here’s a quick look at some key protocols used today:

1. IPsec : Secures IP communications using encryption and authentication. Commonly used in VPNs to protect data over public networks.

2. Kerberos : Provides secure authentication and Single Sign-On (SSO), allowing users to access multiple services with one login while protecting credentials.

3.SSH (Secure Shell) : Enables encrypted remote access to systems and secure file transfers, replacing older insecure remote login tools.

4. Signal Protocol :Offers end to end encryption for messages, voice, and video calls, ensuring only the sender and receiver can access the content.

5. Secure RPC (S-RPC) : Protects remote procedure calls by authenticating services and preventing unauthorized execution of code across networks.

6. TLS (Transport Layer Security) : Encrypts data between clients and servers, widely used in HTTPS, VoIP, and other secure application communications.
