4.4 Electronic signature forms The current clause specifies four forms of XML advanced electronic signatures, namely the Basic Electronic Signature (XAdES-BES), the Explicit Policy based Electronic Signature (XAdES-EPES), and the Electronic Signature with Validation Data (XAdES-T and XAdES-C). Conformance to the present document mandates the signer to create one of these formats. The informative annex B defines extended forms of XAdES. Conformance to the present document does not mandate the signer to create any of the forms defined in annex B.

4.5 Validation process The Validation Process validates an electronic signature, the output status of the validation process can be: - invalid; - incomplete validation; - valid. An Invalid response indicates that either the signature format is incorrect or that the digital signature value fails verification (e.g. the integrity check on the digital signature value fails or any of the certificates on which the digital signature verification depends is known to be invalid or revoked). An Incomplete Validation response indicates that the format and digital signature verifications have not failed but there is insufficient information to determine if the electronic signature is valid. For example; all the required certificates are not available or the grace period is not completed. In the case of Incomplete Validation, the electronic signature may be checked again at some later time when additional validation information becomes available. Also, in the case of incomplete validation, additional information may be made available to the application or user, thus allowing the application or user to decide what to do with partially correct electronic signatures. A Valid response indicates that the signature has passed verification and it complies with the signature validation policy. Informative annex G gives details on technical rules that verifiers should follow for verifying XAdES signatures. 4.6 Arbitration In case of arbitration, a XAdES-C form provides reliable evidence for a valid electronic signature, provided that: - the arbitrator knows where to retrieve the signer's certificate (if not already present), all the required certificates and CRLs, ACRLs or OCSP responses referenced in the XAdES-C; - when time-stamping in the XAdES-T is being used, the certificate from the TSU that has issued the time-stamp token in the XAdES-T format is still within its validity period; - when time-stamping in the XAdES-T is being used, the certificate from the TSU that has issued the time-stamp token in the XAdES-T format is not revoked at the time of arbitration; - when time-marking in the XAdES-T is being used, a reliable audit trail from the Time-Marking Authority is available for examination regarding the time; - none of the private keys corresponding to the certificates used to verify the signature chain have ever been compromised; - the cryptography used at the time the XAdES-C was built has not been broken at the time the arbitration is performed. If the signature policy can be explicitly or implicitly identified then an arbitrator is able to determine the rules required to validate the electronic signature. Annex B (informative): Extended electronic signature forms The XAdES forms specified in clause 4.4 can be extended by addition of certain unsigned properties that are defined in the present document. These properties are applicable for very long term verification, and for preventing some disaster situations which have been identified in the normative part of the present document. The clauses below give an overview of the various forms of extended signature formats in the present document.

Method Detail

values

public static XAdES[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (XAdES c : XAdES.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static XAdES valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
