Abstract
Provided is a process including: obtaining a plurality of records to be protected; forming a tamper-evident log configured to prevent an attacker from undetectably modifying any of the plurality of records stored in the tamper-evident log, wherein the cryptographic hash value of a given entry in the tamper-evident log is sequence agnostic to the sequence of entries in virtue of being based on values that do not specify a position in the sequence of entries; and storing the tamper-evident log in memory.
