Abstract
A first computing system establishes a cryptographically protected communication session with a second computing system by proposing a hybrid cryptographic scheme. In response to the proposed hybrid cryptographic scheme, a second computing system transmits cryptographic materials to the first computing system, and the first computing system transmits cryptographic materials to the second computing system. Using the cryptographic materials, two or more cryptographic keys are derived. One cryptographic key is used to perform an inner cryptographic operation on one or more data items, and another cryptographic key is used to perform an outer cryptographic operation on the one or more data items that have been cryptographically protected by the inner cryptographic operation.
