Abstract
Systems and methods provide security to HTTP applications. Responses sent from a server, such as a web server, are analyzed and a signature is generated for each HTML object in that page. The signature is encrypted and sent to a client along with the contents of the page. When a client later sends a request, the system checks the signature associated with that request with the contents of the request itself. If the values, variables, lengths, and cardinality of the request are validated, then the request is forwarded to the web server. If, on the other hand, the request is invalidated, the request is blocked from reaching the web server, thereby protecting the web server from malicious attacks. The systems and methods offer security without being limited to a session or user.
