Why do you use DelegatingFilterProxy in springSecurity and what are the benefits of this design?
What I don't understand is why this security framework USES proxy classes to invoke filters. What are the benefits of this design?

I think the documentation of DelegatingFilterProxy gives you quite pretty explanation:
[...] All
calls to the filter proxy will then be delegated to that bean in the
Spring context, which is required to implement the standard Servlet
Filter interface.
This approach is particularly useful for Filter implementation with
complex setup needs, allowing to apply the full Spring bean definition
machinery to Filter instances. Alternatively, consider standard Filter
setup in combination with looking up service beans from the Spring
root application context.
NOTE: The lifecycle methods defined by the Servlet Filter interface
will by default not be delegated to the target bean, relying on the
Spring application context to manage the lifecycle of that bean.
Specifying the "targetFilterLifecycle" filter init-param as "true"
will enforce invocation of the Filter.init and Filter.destroy
lifecycle methods on the target bean, letting the servlet container
manage the filter lifecycle. [...]
