Answer: TLS protocols like SSL/TLS makes sure the secure communication through encryption, authentication with digital certificates, and data integrity checks.

Transport Layer Security (TLS) Protocols like SSL/TLS ensure secure communication using below methods:

Encryption

TLS uses the encryption algorithms to encrypt data which is transmitted between a client and a server. This makes sure that even if someone intercepts the data, they cannot understand it without the decryption key.

Authentication

TLS allows authentication between the client and the server. This means both parties need to verify each other’s identities using digital certificates.

Data Integrity

TLS makes sure that data integrity by using cryptographic hash functions. These functions are used mainly to generate unique checksums for data packets. If the data gets changed during transmission, the checksums will not get match and will indicate the problem.

Key Exchange

TLS enables secure key exchange protocols like Diffie-Hellman or Elliptic Curve Diffie-Hellman. These protocols allow the client and server to negotiate and agree upon a secret encryption key without exposing it to potential eavesdroppers.

Certificate Validation

TLS verifies the authenticity of digital certificates presented by the server during the handshake process. This method mainly prevents man-in-the-middle attacks where an attacker tries to copy the server.

Conclusion

In conclusion, TLS protocols such as SSL/TLS ensure secure communication by using encryption, authentication, data integrity checks, key exchange protocols, and certificate validation, collectively creating a robust framework for protecting data during transmission.
