Supporting Invocations Of The Rdtsc (Read Time-Stamp Counter) Instruction By Guest Code Within A Secure Hardware Enclave

US Patent:
2023008, Mar 16, 2023
Filed:
Oct 18, 2022
Appl. No.:
18/047450
Inventors:
- Palo Alto CA, US
ALOK NEMCHAND KATARIA - Pune, IN
MARTIM CARBONE - Palo Alto CA, US
DEEP SHAH - Palo Alto CA, US
International Classification:
G06F 9/48
G06F 9/455
G06F 21/62
G06F 21/53
Abstract:
Techniques for supporting invocations of the RDTSC (Read Time-Stamp Counter) instruction, or equivalents thereof, by guest program code running within a virtual machine (VM), including guest program code running within a secure hardware enclave of the VM, are provided. In one set of embodiments, a hypervisor can activate time virtualization heuristics for the VM, where the time virtualization heuristics cause accelerated delivery of system clock timer interrupts to a guest operating system (OS) of the VM. The hypervisor can further determine a scaling factor to be applied to timestamps generated by one or more physical CPUs, where the timestamps are generated in response to invocations of a CPU instruction made by guest program code running within the VM, and where the scaling factor is based on the activated time virtualization heuristics. The hypervisor can then program the scaling factor into the one or more physical CPUs.

Supporting Migration Of Virtual Machines Containing Enclaves

US Patent:
2021001, Jan 21, 2021
Filed:
Sep 5, 2019
Appl. No.:
16/561051
Inventors:
- Palo Alto CA, US
Martim Carbone - Palo Alto CA, US
Deep Shah - Palo Alto CA, US
International Classification:
G06F 9/455
H04L 29/06
H04L 9/08
Abstract:
The present disclosure provides an approach for migrating the contents of an enclave, together with a virtual machine comprising the enclave, from a source host to a destination host. The approach provides a technique that allows the contents of the enclave to remain secure during the migration process, and also allows the destination host to decrypt the contents of the enclave upon receiving the contents and upon receiving the VM that includes the enclave. The approach allows for the VM to continue execution on the destination host. The enclave retains its state from source host to destination host. Applications using the enclave in the source host are able to continue using the enclave on the destination host using the data migrated from the source host to the destination host.

Secure Enclave-Based Guest Firewall

US Patent:
2020034, Oct 29, 2020
Filed:
Jun 17, 2019
Appl. No.:
16/442579
Inventors:
- Palo Alto CA, US
ALOK NEMCHAND KATARIA - Pune, IN
DEEP SHAH - Palo Alto CA, US
International Classification:
H04L 29/06
G06F 9/455
Abstract:
Techniques for implementing a secure enclave-based guest firewall are provided. In one set of embodiments, a host system can load a policy enforcer for a firewall into a secure enclave of a virtual machine (VM) running on the host system, where the secure enclave corresponds to a region of memory in the VM's guest memory address space that is inaccessible by processes running in other regions of the guest memory address space (including privileged processes that are part of the VM's guest operating system (OS) kernel). The policy enforcer can then, while running within the secure enclave: (1) obtain one or more security policies from a policy manager for the firewall, (2) determine that an event has occurred pertaining to a new or existing network connection between the VM and another machine, and (3) apply the one or more security policies to the network connection.

Validating The Integrity Of Application Data Using Secure Hardware Enclaves

US Patent:
2020021, Jul 9, 2020
Filed:
Mar 8, 2019
Appl. No.:
16/296273
Inventors:
- Palo Alto CA, US
Achindra Bhatnagar - Hyderabad, IN
Sachin Shinde - Pune, IN
Martim Carbone - Palo Alto CA, US
Deep Shah - Palo Alto CA, US
International Classification:
G06F 21/12
G06F 21/60
G06F 21/62
G06F 21/64
H04L 9/32
Abstract:
Techniques for verifying the integrity of application data using secure hardware enclaves are provided. In one set of embodiments, a client system can create a secure hardware enclave on the client system and load program code for an integrity verifier into the secure hardware enclave. The client system can further receive a dataset from a server system and store the dataset at a local storage or memory location, and receive, via the integrity verifier, a cryptographic hash of the dataset from the server system and store the received cryptographic hash at a memory location within the secure hardware enclave. Then, on a periodic basis, the integrity verifier can compute a cryptographic hash of the stored dataset, compare the computed cryptographic hash against the stored cryptographic hash, and if the computed cryptographic hash does not match the stored cryptographic hash, determine that the stored dataset has been modified.
