  • Patent number: 11244056
    Abstract: A trusted threat-aware microvisor may be deployed as a module of a trusted computing base (TCB). The microvisor is illustratively configured to enforce a security policy of the TCB, which may be implemented as a security property of the microvisor. The microvisor may manifest (i.e., demonstrate) the security property in a manner that enforces the security policy. Trustedness denotes a predetermined level of confidence that the security property is demonstrated by the microvisor. The predetermined level of confidence is based on an assurance (i.e., grounds) that the microvisor demonstrates the security property. Trustedness of the microvisor may be verified by subjecting the TCB to enhanced verification analysis configured to ensure that the TCB conforms to an operational model with an appropriate level of confidence over an appropriate range of activity. The operational model may then be configured to analyze conformance of the microvisor to the security property.

  • Patent number: 10592678
    Abstract: The embodiments herein are directed to a technique for providing secure communication between nodes of a network environment or within a node of the network using a verified virtual trusted platform module (TPM) of each node. The verified virtual TPM illustratively emulates a hardware TPM device to provide software key management of cryptographic keys used to provide the secure communication over a computer network of the network environment. Illustratively, the verified virtual TPM is configured to enforce a security policy of a trusted code base (TCB) that includes the virtual TPM. Trustedness denotes a predetermined level of confidence that the security property is demonstrated by the verified virtual TPM. The predetermined level of confidence is based on an assurance (i.e., grounds) that the verified virtual TPM demonstrates the security property.

  • Patent number: 10025691
    Abstract: A technique verifies a compound software code using a modularized architecture. The compound software code may be divided into smaller components or modules that provide various functions (e.g., services) of the code. A set of properties may be defined for the modules, such that the verification technique may be used to verify that the modules manifest those properties, wherein at least one property may be security related and the remaining properties may be related to the services of the modules. The compound software code is divided into smaller modules to facilitate verification of the properties related to the services provided by the modules. Properties of the modules may be verified in accordance with an enhanced verification procedure to demonstrate that the modules manifest those properties and transform those modules into verified code bases (VCBs).
