Why is an SSL certificate important for the latest Google update?

Most of the businesses are online these days and there is a list of information we provide on these portals which is sensitive when it comes to our digital security. When an SSL certificate is installed on a site, it makes sure that the data which the users share with the website is securely delivered to the website without a man-in-the-middle attack.

When SSL is installed on a website, you can securely browse the site with the https:// protocol. If you see a website which doesn’t have an SSL certificate installed and is asking you for your information, refrain from doing so as you might not be sure about the privacy of your data.

The advantages of using a SSL certificate:

• The connection is private (or secure) because symmetric cryptography is used to encrypt the data transmitted. The keys for this symmetric encryption are generated uniquely for each connection and are based on a shared secret negotiated at the start of the session (see TLS handshake protocol. The server and client negotiate the details of which encryption algorithm and cryptographic keys to use before the first byte of data is transmitted The negotiation of a shared secret is both secure (the negotiated secret is unavailable to eavesdroppers and cannot be obtained, even by an attacker who places themselves in the middle of the connection) and reliable (no attacker can modify the communications during the negotiation without being detected).

• The identity of the communicating parties can be authenticated using public-key cryptography. This authentication can be made optional, but is generally required for at least one of the parties (typically the server).

• The connection ensures integrity because each message transmitted includes a message integrity check using a message authentication code to prevent undetected loss or alteration of the data during transmission.

When SSL is used, it gives an extra layer of security and Google knows that the particular website is not a fraudulent data-mining website.
