SYSTEMS, DEVICES, AND METHODS FOR PROTECTING ACCESS PRIVACY OF CACHED CONTENT
Embodiments relate to systems, devices, and computer-implemented methods for preventing determination of previous access of sensitive content by receiving, from a user, a request for content at a device in an information centric network, where a cached version of the content is locally stored at the device; initiating a time delay based on a determination that the user has not previously requested the content; and transmitting the cached version of the content to the user after the time delay.
SYSTEM PERFORMANCE LOGGING OF COMPLEX REMOTE QUERY PROCESSOR QUERY OPERATIONS
Described are methods, systems and computer readable media for performance logging of complex query operations.
PROCESSORS, METHODS, SYSTEMS, AND INSTRUCTIONS TO SUPPORT LIVE MIGRATION OF PROTECTED CONTAINERS
A processor includes a decode unit to decode an instruction that is to indicate a page of a protected container memory, and a storage location outside of the protected container memory. An execution unit, in response to the instruction, is to ensure that there are no writable references to the page of the protected container memory while it has a write protected state. The execution unit is to encrypt a copy of the page of the protected container memory. The execution unit is to store the encrypted copy of the page to the storage location outside of the protected container memory, after it has been ensured that there are no writable references. The execution unit is to leave the page of the protected container memory in the write protected state, which is also valid and readable, after the encrypted copy has been stored to the storage location.
Extracting Malicious Instructions on a Virtual Machine in a Network Environment
A system including a guest virtual machine with one or more virtual machine measurement points configured to collect virtual machine operating characteristics metadata and a hypervisor control point configured to receive virtual machine operating characteristics metadata from the virtual machine measurement points. The hypervisor control point is further configured to send the virtual machine operating characteristics metadata to a hypervisor associated with the guest virtual machine. The system further includes the hypervisor configured to receive the virtual machine operating characteristics metadata and to forward the virtual machine operating characteristics metadata to a hypervisor device driver in a virtual vault machine. The system further includes the virtual vault machine configured to determine a classification for the guest virtual machine based on the virtual machine operating characteristics metadata and to send the determined classification to a vault management console.
Quantum key distribution-based key exchange orchestration service
In one embodiment, a secure computing system comprises a key generation sub-system configured to generate cryptographic keys and corresponding key labels for distribution to computer clusters, each computer cluster including a plurality of respective endpoints, a plurality of quantum key distribution (QKD) devices connected via respective optical fiber connections, and configured to securely distribute the generated cryptographic keys among the computer clusters, and a key orchestration sub-system configured to manage caching of the cryptographic keys in advance of receiving key requests from applications running on ones of the endpoints, and provide respective ones of the cryptographic keys to the applications to enable secure communication among the applications.
COMPUTER DATA SYSTEM DATA SOURCE REFRESHING USING AN UPDATE PROPAGATION GRAPH
Described are methods, systems and computer readable media for data source refreshing.
SUPPORTING FAULT INFORMATION DELIVERY
A processor implementing techniques to supporting fault information delivery is disclosed. In one embodiment, the processor includes a memory controller unit to access an enclave page cache (EPC) and a processor core coupled to the memory controller unit. The processor core to detect a fault associated with accessing the EPC and generate an error code associated with the fault. The error code reflects an EPC-related fault cause. The processor core is further to encode the error code into a data structure associated with the processor core. The data structure is for monitoring a hardware state related to the processor core.
TECHNIQUES FOR METADATA PROCESSING
Techniques are described for metadata processing that can be used to encode an arbitrary number of security policies for code running on a processor. Metadata may be added to every word in the system and a metadata processing unit may be used that works in parallel with data flow to enforce an arbitrary set of policies. In one aspect, the metadata may be characterized as unbounded and software programmable to be applicable to a wide range of metadata processing policies. Techniques and policies have a wide range of uses including, for example, safety, security, and synchronization. Additionally, described are aspects and techniques in connection with metadata processing in an embodiment based on the RISC-V architecture.
Application Code Hiding Apparatus by Modifying Code in Memory and Method of Hiding Application Code Using the Same
An application code hiding apparatus includes a secret code dividing part, a secret code caller generating part, a code analyzing part, a dummy code generating part, a code encrypting part, a code disposing part, a code decryptor generating part, a disposed code importer generating part, a code loader generating part, a memory inner code modifier generating part and a decrypted code caller generating part.
APPLICATION-DRIVEN STORAGE SYSTEMS FOR A COMPUTING SYSTEM
Systems and methods that allow secure application-driven arbitrary compute in storage devices in a cloud-based computing system are provided. A computing system including a compute controller configured to: (1) provide access to host compute resources, and (2) operate in at least one of a first mode or a second mode is provided. The computing system may further include a storage controller configured to provide access to storage systems including storage components, at least one compute component, and at least one cryptographic component.
