A system and apparatus for data confidentiality in a distributed ledger are disclosed. The system and apparatus preserve qualities of distributed ledgers, such as transparency, integrity, and redundancy, while also providing confidentiality, scalability, and security not previously available in distributed ledgers. The system includes a data confidentiality module that exploits a trusted execution environment for both transaction processing and key synchronization. The apparatus accessing the distributed ledger provides for new nodes joining the network, sending transactions to the ledger by existing nodes, securely processing the transaction using the trusted execution environment, securing transmission to the logic layer for application of business logic, reading and writing data to local storage, and reading encrypted transactions.

A heterogeneous processor architecture and a method of booting a heterogeneous processor is described. A processor according to one embodiment comprises: a set of large physical processor cores; a set of small physical processor cores having relatively lower performance processing capabilities and relatively lower power usage relative to the large physical processor cores; and a package unit, to enable a bootstrap processor. The bootstrap processor initializes the homogeneous physical processor cores, while the heterogeneous processor presents the appearance of a homogeneous processor to a system firmware interface.

Technologies for secure server access include a client computing device that loads a license agent into a secure enclave established by a processor of the client computing device. The license agent receives a request from an application to access a remote server device. The license agent opens a secure connection with the server device and performs remote attestation of the secure enclave. The license agent authenticates the user and transmits a machine identifier and a user identifier to the server device. The machine identifier may be based on an enclave sealing key of the client computing device. The server device verifies that the machine identifier and the user identifier are bound to a valid application license. If the machine identifier and the user identifier are successfully verified, the application communicates with the server device using the secure connection. Other embodiments are described and claimed.

Embodiments of apparatus, computer-implemented methods, systems, devices, and computer-readable media are described herein for identifying and encrypting a subset of a plurality of instructions, for execution in a more secure execution environment. In various embodiments, the subset may include a single entry point and a single exit point. In various embodiments, one or more instructions of the plurality of instructions that precede or follow the subset may be executed in a first execution environment with a first security level. In various embodiments, the subset may be executed in a second execution environment with a second security level that is more secure than the first security level.
