  This paper considers a source, which employs random linear coding (RLC) to
encode a message, a legitimate destination, which can recover the message if it
gathers a sufficient number of coded packets, and an eavesdropper. The
probability of the eavesdropper accumulating enough coded packets to recover
the message, known as the intercept probability, has been studied in the
literature. In our work, the eavesdropper does not abandon its efforts to
obtain the source message if RLC decoding has been unsuccessful; instead, it
employs partial packet recovery (PPR) offline in an effort to repair
erroneously received coded packets before it attempts RLC decoding again.
Results show that PPR-assisted RLC decoding marginally increases the intercept
probability, compared to RLC decoding, when the channel conditions are good.
However, as the channel conditions deteriorate, PPR-assisted RLC decoding
significantly improves the chances of the eavesdropper recovering the source
message, even if the eavesdropper experiences similar or worse channel
conditions than the destination.
