Abstract: Systems and methods of the inventive subject matter are directed to route optimization that takes sales ratings into consideration. In some embodiments, users can request one of two different route types, a sales route or an optimized route. A sales route allows the user to hand pick waypoints to be visited, and the platform server then generates a route that visits all those waypoints. The route accounts for sales ratings that the user has assigned to each waypoint, as well as times and distances between each waypoint. An optimized route selects waypoints based on previously assigned sales ratings and then generates a route for the user, where the route similarly accounts for sales ratings as well as times and distances between each waypoint. Genetic algorithm techniques can be used to converge on high performing routes.

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.

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.

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.

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.

Abstract: Information from a circuit design's unified power format (UPF) description is utilized to automate the management of reset domain crossings (RDCs). The UPF description is utilized to identify signals that generate both RDC and power domain crossings (PDCs), thereby allowing a circuit designer to efficiently utilize a common (shared) isolation circuit that functions to manage both the RDC (i.e., during reset functions) and the PDC (i.e., during power management functions). A modified UPF description is introduced that facilitates automated management of RDC issues by treating the reset domains as pseudo-power domains, and utilizing UPF analysis and verification tools to automatically generate both shared and non-shared resources for both RDC and PDC issues.
