Secure communication protocols

Secure communication protocols are rules that help two or more parties exchange information safely over the internet. They encrypt, or scramble, data so that only the intended recipient can understand it. This prevents hackers from intercepting or tampering with the messages. Protocols like HTTPS (used in secure websites) establish trusted connections by verifying identities and encrypting data. Overall, they ensure confidentiality, integrity, and authenticity of online communications, protecting sensitive information such as passwords, personal details, and financial data from unauthorized access.
