MASHAUTH: USING MASHSSL FOR EFFICIENT DELEGATED AUTHENTICATION

The present invention provides a method that allows the MashSSL protocol to be used to provide a secure and efficient way for delegated authentication. The invention allows services which already have an SSL infrastructure to reuse that infrastructure for delegated authentication, and to do so in a fashion where the cryptographic overhead is amortized across multiple users, and which provides the user with greater control of what information is shared on their behalf.
