This secured channel helps protect your search terms and search results pages from being intercepted by a third party on the network.
Difference between Google SSL & usual Google
End user functionality of Google Search remains same. However, data sent from your PC to Google is encrypted and transferred in more secured manner while using Google SSL search. Google still receives all data while you use either type of Google Search.
