SIST-TS ETSI/TS 101 733 V1.3.1:2005

Electronic signature formats

The scope of this activity is to elaborate on the basic concepts and concerns regarding signature policies as presented in ETSI ES 201 733 and make such concepts accessible to application developers and potential users. This work item shall take advantage of the study on signature policies made under the ISIS program.   This deliverable shall be an explanatory part that will be partly tutorial and partly descriptive that translates the standard into real world terms. The deliverable shall be included into TS 101 733 as an informative annex.
