HTTPS ensures authenticity through the use of digital certificates and encryption.
When a user connects to a website using HTTPS, the website’s server sends a digital certificate to the user’s browser. This certificate includes information such as the website’s identity and the public key needed to establish an encrypted connection.
The user’s browser then verifies the authenticity of the digital certificate by checking it against a trusted certificate authority (CA). If the certificate is valid, the browser establishes a secure connection using encryption.
This encryption ensures that any data sent between the user’s browser and the website’s server is protected from interception by third parties. This means that even if someone tries to intercept the data, they will not be able to read or modify it.
Therefore, HTTPS ensures authenticity by verifying the identity of the website and protecting the transmission of data through the use of encryption.
