Abstract

A bitstream for configuration of a programmable logic device is received, the bitstream comprising a data segment and authentication data associated with the data segment. The programmable logic device computes a hash of the data segment. The programmable logic device compares the computed hash of the data segment with the authentication data. Configuration of the programmable logic device halts responsive to a determination that the computed hash of the data segment does not match the authentication data. Configuration of the programmable logic device using the data segment continues responsive to a determination that the computed hash of the data segment matches the authentication data.
