Keeping correct and informative log files is crucial for system maintenance, security and forensics. Cryptographic logging schemes offer integrity checks that protect a log file even in the case where...
We present four attacks on three cryptographic schemes intended for securing log files against illicit retroactive modification. Our first two attacks regard the LogFAS scheme by Yavuz et al. (Financi...
Forward-secure logging protects old log entries in a log file against an adversary compromising the log device. However, we show that previous work on forward-secure logging is prone to crash-attacks ...
