ABSTRACT:
Improvements in security processing are disclosed which enable security processing to be transparent to the application. Security processing (such as Secure Sockets Layer, or “SSL”, or Transport Layer Security, or “TLS”) is performed in (or controlled by) the stack. A decision to enable security processing on a connection can be based on configuration data or security policy, and can also be controlled using explicit enablement directives. Directives may also be provided for allowing applications to communicate with the security processing in the stack for other purposes. Functions within the protocol stack that need access to clear text can now be supported without loss of security processing capability. No modifications to application code, or in some cases only minor modifications (such as inclusion of code to invoke directives), are required to provide this security processing. Improved offloading of security processing is also disclosed, which provides processing efficiencies over prior art offloading techniques. Offload components can be controlled from the kernel, an SSL layer or an application.
