US 2019/0199692 A1 · LOGIC REPOSITORY SERVICE USING ENCRYPTED CONFIGURATION DATA

Abstract

The following description is directed to a logic repository service. In one example, a method of a logic repository service can include receiving a first request to generate configuration data for configurable hardware using a specification for application logic of the configurable hardware. The method can include generating the configuration data for the configurable hardware. The configuration data can include data for implementing the application logic. The method can include encrypting the configuration data to generate encrypted configuration data. The method can include signing the encrypted configuration data using a private key. The method can include transmitting the signed encrypted configuration data in response to the request.

Dependent claims

A method comprising:

generating configuration data for application logic of a field-programmable gate array (FPGA), the FPGA comprising host logic and the application logic when the FPGA is fully configured;
generating a validated partial bitstream based on the application logic and the host logic, the validated partial bitstream specifying the configuration data for application logic of the FPGA;
encrypting the validated partial bitstream to generate an encrypted bitstream;
signing the encrypted bitstream using a private key to generate a signed encrypted bitstream, the signed encrypted bitstream comprising a signature and the encrypted bitstream;
and
transmitting the signed encrypted bitstream to a host server computer in communication with a particular FPGA as part of a programming sequence to configure the FPGA with the host logic and the application logic.
