WebCisco in 2024, a security firm exposed a security vulnerability in millions of Cisco routers, where an attacker can remotely gain root access to the router and reprogram the FPGA configuration bitstream to disable the Trust Anchor Module (TAm), which protects against boot-time exploits [1]. A few years back it was WebThe readback of bitstream data is a possible attack vector for ... reversal is feasible, which would present a security problem.

WebWollinger et al. [9] provide a summary of security issues while doing cryptography on an FPGA, with a focus on how to maintain cryptographic secrets within the FPGA in the face of attacks like attempting to read out the FPGA’s bitstream “readback attack”, its internal SRAM, and so on. If WebWhile the readback bitstream can potentially be used to recreate the configuration bitstream, there are easier ways to capture the configuration bitstream. It is this latter characteristic that is of much greater concern from a security perspective, because operational data can be recovered. Side-Channel WebTo verify the readback data stream, compare it to the RBD golden readback file and masking readback bits with the MSD file. This approach is simple because there is a 1:1 correspondence between the start of the readback data stream and the start of the RBD and MSD files, making the task of aligning readback, mask, and expected data easier. simpson feet
