110 1 Introduction
111 The DSS signing and verifying protocols are defined in [DSSCore]. As defined in that document,
112 these protocols have a fair degree of flexibility and extensibility. This document profiles the core
113 to support creation and validation of a "seal" created by a given Entity or Organization on
114 electronic data.
115 The seal is a form of electronic signature which:
116 a) protects the integrity of the document,
117 b) includes the time at which the seal was applied proving that the data existed at the given
118 time,
119 c) includes the identity of the entity requesting the seal,
120 d) may include a statement of intent for applying the seal.
121 This profile includes a few options that require further profiling for implementing interoperable
122 systems.
123 1.1 Terminology
124 The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
125 "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this specification are to be
126 interpreted as described in IETF RFC 2119 [RFC 2119]. These keywords are capitalized when
127 used to unambiguously specify requirements over protocol features and behavior that affect the
128 interoperability and security of implementations. When these words are not capitalized, they are
129 meant in their natural-language sense.
130 This specification uses the following typographical conventions in text: ,
131 Attribute, Datatype, OtherCode.
132 1.2 Namespaces
133 Conventional XML namespace prefixes are used in this document:
134 · The prefix dss: (or no prefix) stands for the DSS core namespace [Core-XSD].
135 · The prefix ds: stands for the W3C XML Signature namespace [XMLSig].
136 · The prefix xades: stands for the ETSI XML Advanced Electronic Signature namespace
137 [XAdES]
138 Applications MAY use different namespace prefixes, and MAY use whatever namespace
139 defaulting/scoping conventions they desire, as long as they are compliant with the Namespaces
140 in XML specification [XML-ns].

161 2 Profile Features
162 2.1 Identifier
163 urn:oasis:names:tc:dss:1.0:profiles:eseal
164 2.2 Scope
165 This document profiles the DSS signing and verifying protocols defined in [DSSCore] and profiles
166 the XML signature format for entity seals created by a given Entity or Organization on electronic
167 data.
168 2.3 Relationship To Other Profiles
169 This document profiles the DSS signing and verifying protocols defined in [DSSCore].
170 2.4 Signature Object
171 This profile supports the creation and verification of [XMLSig] signatures as defined in section 5.
172 2.5 Transport Binding
173 This profile is transported using the HTTP POST Transport Binding defined in [DSSCore].
174 2.6 Security Binding
175 2.6.1 Security Requirements
176 This profile MUST use security bindings that:
177 · Authenticates the requester to the DSS server
178 · Authenticates the DSS server to the DSS client
179 · Protects the integrity or a request, response and the association of response to the
180 request.
181 · Optionally, protects the confidentiality of a request and response
182 The following is recommended to meet these requirements..
183 2.6.2 TLS X.509 Mutual Authentication
184 This profile is secured using the TLS X.509 Mutual Authentication Binding defined in [DSSCore].

187 3.1.1 Element
188 The optional inputs from [DSSCore]:
189 · MUST be supported by the DSS server. This MAY be sent
190 by the client to provide the claimed identity of the requester. If present the
191 element of MUST be authenticated by the Security Binding.
192 · MAY be supported by the DSS server. If present this
193 MAY be used by the client to request the CommitmentTypeIndication property. The
194 CommitmentTypeIndication property is requested using the identifier and value as
