HOMOMORPHIC ENCRYPTION FOR WEB APPLICATION FIREWALL PROCESSING

Abstract: a method and apparatus for avoiding exposure of data that was entered into a web application in the context of having that data scanned by a third-party web application firewall (waf). the apparatus receives, in response to forwarding a request to a web application, a response from the web application that includes a web form. the apparatus forwards the response to a browser and in response receives a second request that includes a version of the web form modified by the browser such that data entered into a plurality of fields of the web form was extracted, aggregated, and homomorphically encrypted. the apparatus causes the second request to be scanned by the third party waf using one or more homomorphic encryption signatures, and in response to the scanning determines whether to forward the second request to the web application or take corrective action.
