Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electronic Signatures and Infrastruc

26、tures (ESI). Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “may not“, “need“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of prov

27、isions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The present document defines an algorithm to validate electronic signatures, with special consideration on signature validation of “old“ electronic signatures, where certificates may

28、 have expired or been revoked or even the usage period of algorithms have been exceeded. It does so by capitalizing on security measures that have been applied by e.g. the signer or previous verifiers and ensures that such signatures still can be validated. It is agnostic to the type of security mea

29、sures; while it is primarily aiming at Advanced Electronic Signatures, which provide such features intrinsically, but it also allows for variations, like classical archiving services, where the security measures may also be non-cryptographic. The way the algorithm is presented aims at clarity and un

30、derstandability. It is not assumed, nor recommended, that the algorithm will be implemented as described. Efficiency and other implementational aspects were not considered. A conformant implementation will provide the same results, however, as the algorithm here would. An efficient implementation wi

31、ll need to reorder steps in algorithms, use caching of results wherever possible and do things in parallel, if possible. Signature validation is driven by a signature validation policy. The algorithm presented here supports such policies. It is assumed that the validator, represented by the driving

32、application, provides such a policy in possibly different forms - as a formal policy, as a set of configuration parameters, or by the way the algorithm has been implemented. To avoid confusing terms, the term constraint is used for a single policy rule that influences decisions made by the algorithm

33、. A formal signature policy, as specified in i.3, can provide a set of constraints, which may be used exclusively or may be combined with other constraints (e.g. coming from local configuration). ETSI ETSI TS 102 853 V1.2.1 (2014-12)71 Scope The present document specifies procedures for establishing

34、 whether an electronic signature is technically valid based on the considerations specified in the present document and the validation constraints are applied to the verification procedures. These constraints may be specified as part of a formal signature policy. It is outside the scope of the prese

35、nt document as to whether a signature is accepted by the relying party and specifically if it bears legal validity. NOTE: Factors outside the scope of the present document, such as delays in reporting revocations or unintended data errors in a document, may impact on the signature and so may need to

36、 be taken into account in considering the technical validity of a signature in case of dispute. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-sp

37、ecific references, the latest version of the reference document (including any amendments) applies. Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference.
