Abstract: In various examples there is a computing device in communication with at least one other computing device via a communications network. The computing device has a memory and a central processing unit having a trusted execution environment comprising trusted regions of the memory. The computing device has an operating system configured to create a memory mapping between a virtual address space of the memory and a memory of the at least one other computing device and to provide details of the memory mapping to the trusted execution environment. The trusted execution environment is configured to execute an application which is able to communicate with the other computing device directly using the memory mapping provided by the operating system.

Abstract: In various examples a compute node is described. The compute node has a central processing unit which implements a hardware transactional memory using at least one cache of the central processing unit. The compute node has a memory in communication with the central processing unit, the memory storing information comprising at least one of: code and data. The compute node has a processor which loads at least part of the information, from the memory into the cache. The processor executes transactions using the hardware transactional memory and at least the loaded information, such that the processor ensures that the loaded information remains in the cache until completion of the execution.

Abstract: A multi-party privacy-preserving machine learning system is described which has a trusted execution environment comprising at least one protected memory region. An code loader at the system loads machine learning code, received from at least one of the parties, into the protected memory region. A data uploader uploads confidential data, received from at least one of the parties, to the protected memory region. The trusted execution environment executes the machine learning code using at least one data-oblivious procedure to process the confidential data and returns the result to at least one of the parties, where a data-oblivious procedure is a process where any patterns of memory accesses, patterns of disk accesses and patterns of network accesses are such that the confidential data cannot be predicted from the patterns.
