1 Scope This Technical Report explains how to provide and use time-stamping services so that time-stamp tokens are effective when used to provide timeliness, data integrity, and non-repudiation services in conjunction with other mechanisms. It defines:
— how time-stamp requesters should use time-stamp token generation services;
— how TSAs ( time-stamping authorities ) should provide a service of guaranteed quality;
— how TSAs should deserve trust based on good practices;
— which algorithms and parameters should be used in TST ( time-stamp token ) generation and TST renewal, so that TSTs resist during the time period during which the TSTs can be verified as being valid;
— how time-stamp verifiers should use the time-stamp token verification services, both when validating individual TSTs , and when validating sequences of renewal TSTs .
