Abstract
Audit logs, given that information about
the existing and past states of systems, are one of the
nearly all significant parts of current computer
systems provided that protection for audit logs on an
untrusted machine in a huge distributed system is a
difficult task, particularly in the occurrence of active
adversaries. In such a system, it is decisive to have
ahead protection such that when an opposition
compromise a machine, she cannot adjust or build
the log entry accumulate previous to the conciliation.
We propose a narrative forward secure and
collective logging scheme call sightless collective
ahead logging scheme, which is appropriate for huge
distributed systems. Sightless collective ahead can
create widely verifiable ahead secure and collective
signatures with near-zero computational, storage,
and communication costs for the loggers, without
require any online trusted third party support.
