Techniques for sharing private data objects in a trusted execution environment using a distributed ledger are described. The techniques described herein may enable sharing of data objects, referred to herein as private data objects (PDOs), between individuals and organizations with access and update policies mediated by execution of code (referred to herein as a 'smart contract') carried with the PDO in a secure enclave. A distributed ledger may serve as a “public commit log” to ensure that there is a single, authoritative instance of the object and provide a means of guaranteeing atomicity of updates across interacting objects.

Techniques for shared private data objects in a trusted execution environment

Techniques for sharing private data objects in a trusted execution environment using a distributed ledger are described. The techniques described herein may enable sharing of data objects, referred to herein as private data objects (PDOs), between individuals and organizations with access and update policies mediated by execution of code (referred to herein as a 'smart contract') carried with the PDO in a secure enclave. A distributed ledger may serve as a 'public commit log' to ensure that there is a single, authoritative instance of the object and provide a means of guaranteeing atomicity of updates across interacting objects.

A method and system to provide user-level multithreading are disclosed. The method according to the present techniques comprises receiving programming instructions to execute one or more shared resource threads (shreds) via an instruction set architecture (ISA). One or more instruction pointers are configured via the ISA; and the one or more shreds are executed simultaneously with a microprocessor, wherein the microprocessor includes multiple instruction sequencers.

Method and system to provide user-level multithreading

An automated method to verify a block record for a digital ledger involves a first validation node (FVN) which receives a block record from a second validation node (SVN). The block record comprises a digital signature for the block record. In response to receiving the block record, the FVN automatically obtains a node identifier for the SVN, based on the digital signature for the block record. The first validator node uses the node identifier for the SVN to determine whether the SVN belongs to a validation group that comprises the FVN. The FVN uses an attestation service to determine whether the node identifier for the SVN belongs to a node with a trusted processor. The FVN determines whether the digital signature for the block record was created with a private key that corresponds to the node identifier for the SVN.

Technology for secure partitioning and updating of a distributed digital ledger

In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.

Mechanism for instruction set based thread execution on a plurality of instruction sequencers

Mechanism for instruction set based thread execution of a plurality of instruction sequencers

Embodiments of apparatuses, methods, and systems for modifying the behavior of a guest installed to run within a VM are disclosed. In one embodiment, an apparatus includes virtualization logic, first storage, second storage, decode logic, and multiplexing logic. The virtualization logic is to provide a mode in which to operate a virtual machine. The first storage is to store a first plurality of micro-instructions to control the apparatus. The second storage is to store a second plurality of micro-instructions to control the apparatus. The decode logic is to decode a macro-instruction into one of a first plurality and a second plurality of micro-instructions. The multiplexing logic is to cause the macro-instruction to be decoded into the second plurality of micro-instructions instead of the first plurality of micro-instructions only when issued from the virtual machine.

Guest-specific microcode

In one embodiment, the present invention includes a method for directly communicating between an accelerator and an instruction sequencer coupled thereto, where the accelerator is a heterogeneous resource with respect to the instruction sequencer. An interface may be used to provide the communication between these resources. Via such a communication mechanism a user-level application may directly communicate with the accelerator without operating system support. Further, the instruction sequencer and the accelerator may perform operations in parallel. Other embodiments are described and claimed.
