Systems and methods providing a processing device to receive, by a software build process executing in a trusted execution environment (TEE) of a first computer system, software source code from a second computer system. The processing device generates a software package by compiling the software source code. The processing device also receives, from the second computer system, a signing key associated with the second computer system. The processing device further signs the software package using the signing key associated with the second computer system. The processing device then deploys the signed software package on the first computer system.

Management of local signing of software packages using a trusted execution environment

Systems and methods for implementing trusted clients using secure execution environments. An example method comprises: receiving, by a server, a measurement from a client application running in a secure execution environment implemented by a client computing device; responsive to validating the measurement, transmitting a first confidential data item to the client application running in the secure execution environment; receiving, from the client application running in the secure execution environment, a second confidential data item derived from a local state of the client application modified by the first confidential data item; and updating, in view of the second confidential data item, a local state of a server application.

Implementing trusted clients using secure execution environments

A system and method for using a blockchain provenance system to determine and/or track the qualitative issues associated with the supply chain state of one or more products, including obtaining a product identifier and a first set of parameters associated with the product identifier, each parameter indicative of a supply chain state of a product corresponding to the product identifier; determining, in view of the set of parameters, a first set of qualitative issues associated with the supply chain state of the product; and updating a ledger of a blockchain system to indicate an association between the product identifier and the first set of qualitative issues associated with the supply chain state of the product.

Tracking qualitative parameters using a blockchain provenance system

The technology disclosed herein enables network consensus management using trusted execution environments. An example method can include: determining, using a processing device associated with a first trusted execution environment (TEE) for a first node of a network in a distributed computing system, that the first node is a leader for a first set of networking transactions processed by the network in the distributed computing system; determining using the processing device associated with the first TEE, whether a second node of the network in the distributed computing system comprises a second TEE that satisfies an authentication threshold; and responsive to determining that the second node comprises the second TEE that satisfies the authentication threshold, setting, using the processing device associated with the first TEE, the second TEE of the second node as the leader for a second set of networking transactions processed by the network in the distributed computing system.

Network management using trusted execution environments

Notification system using a blockchain system. A method of the disclosure includes determining, by a node of a blockchain system, that a notification is available for an application of a computing device. The application is associated with a service platform. The method also includes updating a ledger of the blockchain system to indicate that the notification for the application is available.

Determining blockchain ledger indicates notification availability for an application

Systems and methods providing a processing device to receive, by a software build process executing in a trusted execution environment (TEE) of a first computer system, software source code from a second computer system. The processing device generates a software package by compiling the software source code. The processing device also generates a first signature of the software package and sends the first signature to the second computer system. Responsive to receiving, from the second computer system, a second signature comprising the first signature signed by the second computer system, the processing device further deploys the software package on the first computer system.
