Abstract

At least one secure object of a security module is bound to a secure guest. A trusted component determines whether metadata of the secure guest includes a confidential binding attribute for the security module. Based on determining that the metadata includes the confidential binding attribute, the trusted component configures the security module for the secure guest in a select mode. The select mode prevents certain operations from being intercepted by a hypervisor associated with the secure guest. The trusted component intercepts a security module communication and performs a cryptographic operation on one or more secure objects of the security module communication using the confidential binding attribute to provide a cryptographic result. An outcome of the security module communication, which includes the cryptographic result, is provided to a receiver.
