]> Authority An authority, or origin, of a graph; such as a person or company. Warrant A relationship between an authority and a graph, in which the authority is in some way an origin of that graph. Warrants may include a digital signature of the graph by the authority. asserted by The subject graph originates from and is asserted by the authority specified for the object warrant. The statements expressed in the graph are taken to be claims made by that authority. This property has performative semantics. quoted by The subject graph originates from the authority specified for the object warrant. The statements expressed in the graph are not taken to be claims made by that authority, insofar as any statement using this property is concerned. authority The object authority is the origin of the graph with which the subject warrant is associated. valid from Defines a point in time until which the warrant is valid. valid from Defines a point in time after which the warrant is valid. signature The object is the signature to be used to authenticate the graph with which the subject warrant is associated. signature method The object is the signature method by which the signature specified for the warrant subject was constructed. Signature Method A method used for creating a signature used to authenticate a graph. Signature methods define an canonicalization method and a signature algorithm. Canonicalization Algorithm An algorithm used to transform a graph to a canonical form. Signature Algorithm An algorithm to compute a hash digest from some data and to sign the digest. canonicalization algorithm Canonicalization method used by this signature or digest method. signature algorithm Signature algorithm used by this signature method. digest The object contains a digest value for the subject graph. digest method The object is the digest method by which the digest value specified for the graph subject was constructed. Digest Method A method used for computing a digest a graph. Digest method defines a canonicalization alorithm and a digest algorithm. Digest Algorithm A hash algorithm to compute a digest from some data. signature algorithm Digest algorithm used by this digest method. has key The object is some kind of public key which belongs to the authority. key info The object is some kind of public key which can be used to validate the signature attached to the warrant. certificate The object is a binary (ASN.1 DER) X.509 certificate containing the public key of the authority. This property is similar to the xmldsig#rawX509Certificate property. An alternative to the use of this property is to use swp:hasKey together with swp:X509Certificate. Key Superclass of all classes representing cryptographic key information. DSA key A DSA key as defined by XML-Signature in http://www.w3.org/TR/xmldsig-core/ The XML-Signature P Q G Y J Seed and PgenCounter properties should be used to describe the key. RSA key A RSA key as defined by XML-Signature in http://www.w3.org/TR/xmldsig-core/ The XML-Signature Modulus and Exponent properties should be used to describe the key. PGP key A PGP key as defined by XML-Signature in http://www.w3.org/TR/xmldsig-core/ The XML-Signature PGPKeyID and PGPKeyPacket properties should be used to describe the key. X509 Certificate A X509 certificate as defined by XML-Signature in http://www.w3.org/TR/xmldsig-core/ The XML-Signature X509IssuerSerial X509SubjectName X509SKI X509Certificate properties should be used to describe the certificate. certification authority The object is the certification authority which issed the X509 certificate. Certification Authority An authority which issues certificates.
