Brief about SSL

SSL stands for “Secure Socket Layer”. Historically SSL is used for protecting personal information and sensitive content over the wire. For example, the users make a fund transfer over the internet from own account to other accounts. SSL encrypts the information passed over the internet using standard encryption algorithms. This prevents interception of intermediary sites. This is commonly called “Man-in-the-Middle (MIM)” attack. Data transfer over SSL is a safe and time tested approach for digital transactions.

SSL Search

The above technique can be extended to user search actions and search results over the internet. It offers a secure user experience and addresses their privacy concerns.  Why SSL search is required? Users may want to apply privacy and protection over what they search and what they see as an outcome of the search. Search is personal and the terms are heavily user driven. Users perform the search on the search engines website. The search query is passed to the server typically as a “Get” request. The request is visible through naked eyes which exposes a risk of accessing them to trap personal information. This is especially applicable if the user browses over unsecured wifi or other networks. User search results are also shown in a much open manner on the browsers. There is a high chance of these data like search query and results can be sniffed over network. SSL offers privacy and protection by encrypting the data back and forth during search. More recently (18th October 2011) Google launched its encrypted search for all users adopting to HTTPS everywhere policy. If you use (non SSL), both the search query and source (Google) can be tracked via http referrer field. But if one use for search queries, the search queries will be encrypted and only the source can be tracked
