Introduction 80 In the operational use of the RPKI it can become necessary to 81 contact, human to human, the party responsible for a resource-owning 82 certificate. An important example is when the owner of a Route 83 Origin Authorization (ROA) sees a problem, or an impending problem, 84 with a certificate or CRL in the path between the ROA and a trust 85 anchor. E.g., a certificate along that path has expired, is soon to 86 expire, or a CRL associated with a CA along the path is stale, thus 87 placing the quality of the routing of the address space described by 88 the ROA in jeopardy. 90 As the names in RPKI certificates are intentionally hashes which are 91 not meaningful to humans, see [I-D.ietf-sidr-cp], there is no way to 92 use a certificate itself to lead to the worrisome certificate's or 93 CRL's maintainer. So, "Who do you call?" 95 This document specifies the RPKI Ghostbusters Record, an object 96 signed, indirectly via an End Entity (EE) certificate, by the 97 certificate whose maintainer may be contacted using the human usable 98 payload information in the Ghostbusters Record. 100 The Ghostbusters Record conforms to the syntax defined in 101 [I-D.ietf-sidr-signed-object]. 103 Note that the Ghostbusters Record is not an identity certificate, but 104 rather an attestation to the contact data made by the issuer of the 105 certificate signing the Ghostbusters Record. 107 This record is not meant to supplant or be used as resource registry 108 whois data. It gives information about an RPKI certificate 109 maintainer not a resource holder. 111 This specification has three main sections. The first, Section 4, is 112 the format of the contact payload information, a severely profiled 113 vCARD. The second, Section 5, profiles the packaging of the payload 114 as a profile of the RPKI Signed Object Template specification 115 [I-D.ietf-sidr-signed-object]. The third, Section 6, describes the 116 proper validation of the signed Ghostbusters Record. 118 2. Suggested Reading 120 It is assumed that the reader understands the RPKI, 121 [I-D.ietf-sidr-arch], the RPKI Repository Structure, 122 [I-D.ietf-sidr-repos-struct], Signed RPKI Objects, 123 [I-D.ietf-sidr-signed-object], and vCARDs 124 [I-D.ietf-vcarddav-vcardrev]. 126 3. RPKI Ghostbusters Record Payload Example 128 An example of an RPKI Ghostbusters Record payload with all types 129 populated is as follows: 131 BEGIN:vCard 132 VERSION:4.0 133 FN:Human's Name 134 N:Name;Human's;Ms.;Dr.;OCD;ADD 135 ORG:Organizational Entity 136 ADR;TYPE=WORK:;;42 Twisty Passage;Deep Cavern; WA; 98666;U.S.A. 137 TEL;TYPE=VOICE,MSG,WORK:+1-666-555-1212 138 TEL;TYPE=FAX,WORK:+1-666-555-1213 139 EMAIL;TYPE=INTERNET:human@example.com 140 END:vCard 142 4. vCARD Profile 144 The goal in profiling the vCARD is not to include as much information 145 as possible, but rather to include as few types as possible while 146 providing the minimal necessary data to enable one to contact the 147 maintainer of the RPKI data which threatens the ROA[s] of concern. 149 The Ghostbusters vCARD payload is a minimalist subset of the vCARD as 150 described in [I-D.ietf-vcarddav-vcardrev]. 152 BEGIN - pro forma packaging which MUST be the first line in the 153 vCARD and MUST have the value "BEGIN:vCARD" as described in 154 [I-D.ietf-vcarddav-vcardrev]. 156 VERSION - pro forma packaging which MUST be the second line in the 157 vCARD and MUST have the value "VERSION:4.0" as described in 3.6.9 158 of [I-D.ietf-vcarddav-vcardrev]. 160 FN - the name, as described in 6.2.1 of 161 [I-D.ietf-vcarddav-vcardrev], of a contactable person who 162 responsible for the certificate. 164 N - the components of the name of the object the vCard represents, 165 as described in 6.2.2 of [I-D.ietf-vcarddav-vcardrev]. 167 ORG - an organization as described in 6.6.4 of 168 [I-D.ietf-vcarddav-vcardrev]. 170 ADR - a postal address as described in 6.3 of 171 [I-D.ietf-vcarddav-vcardrev]. 173 TEL - a voice and/or fax phone as described in 6.4.1 of 174 [I-D.ietf-vcarddav-vcardrev]. 176 EMAIL - an Email address as described in 6.4.2 of 177 [I-D.ietf-vcarddav-vcardrev] 179 END - pro forma packaging which MUST be the last line in the vCARD 180 and MUST have the value "END:vCARD" as described in 181 [I-D.ietf-vcarddav-vcardrev]. 183 Per [I-D.ietf-vcarddav-vcardrev], the BEGIN, VERSION, FN, N, and END 184 types MUST be included in a record. To be useful, one or more of 185 ADR, TEL, and EMAIL MUST be included. Other types MUST NOT be 186 included. 188 5. CMS Packaging 190 The Ghostbusters Record is a CMS signed-data object conforming to the 191 Signed Object Template for the Resource Public Key Infrastructure, 192 [I-D.ietf-sidr-signed-object]. 194 The ContentType of a Ghostbusters Record is defined as id-ct- 195 rpkiGhostbusters, and has the numerical value of 196 1.2.840.113549.1.9.16.1.35. This OID MUST appear both within the 197 eContentType in the encapContentInfo object as well as the 198 ContentType signed attribute in the signerInfo object. See 199 [I-D.ietf-sidr-signed-object]. 201 eContent: The content of a Ghostbusters Record is described above in 202 Section 4 above. 204 Similarly to a ROA, the Ghostbusters Record is verified using an EE 205 certificate issued under the CA certificate associated with the 206 resource-holding certificate whose maintainer is described in the 207 vCARD. 209 The EE certificate used to verify the Ghostbusters Record is the one 210 that appears in the CMS data structure that contains the payload 211 defined above. 213 This EE certificate MUST describe its internet number resources using 214 the "inherit" attribute, rather than explicit description of a 215 resource set, see [RFC3779]. 217 6. Validation 219 The validation procedure defined in Section 3 of 220 [I-D.ietf-sidr-signed-object] is applied to a Ghostbusters Record. 221 After this procedure has been performed, the Version number type 222 within the payload is checked, and the OCTET STRING containing the 223 vCARD data is extracted. These data are checked against the profile 224 defined in Section 4 of this document. Only if all of these checks 225 pass is the Ghostbusters payload deemed valid and made available to 226 the application that requested the payload. 228 7. Security Considerations 230 Though there is no on the wire protocol in this specification, there 231 are attacks which could abuse the data described. As the data, to be 232 useful, need to be public, little can be done to avoid this exposure. 234 Phone Numbers: The vCARDs may contain real world telephone numbers 235 which could be abused for telemarketing, abusive calls, etc. 237 Email Addresses: The vCARDs may contain Email addresses which could 238 be abused for purposes of spam. 240 Relying parties are warned that the data in a Ghostbusters Record are 241 self-asserted. These data have not been verified by the CA that 242 issued a (CA) certificate to the entity that issued the EE 243 certificate used to validate the Ghostbusters Record. 245 8. IANA Considerations 247 8.1. OID 249 The IANA is requested to register the OID for the Ghostbusters Record 250 in the registry created by [I-D.ietf-sidr-signed-object] as follows: 252 Name OID Specification 253 ----------------------------------------------------------- 254 Ghostbusters 1.2.840.113549.1.9.16.1.35 [ This document ] 256 8.2. File Extension 258 The IANA is requested to add an item for the Ghostbusters Record file 259 extension to the RPKI Repository Name Scheme created by 260 [I-D.ietf-sidr-repos-struct] as follows: 262 Filename Extension RPKI Object Reference 263 ----------------------------------------------------------- 264 .gbr Ghostbusters Record [ This document ] 266 8.3. Media Type 268 The IANA is requested to register the media type application/ 269 rpki-ghostbusters as follows 271 MIME media type name: application 272 MIME subtype name: rpki-ghostbusters 273 Required parameters: None 274 Optional parameters: None 275 Encoding considerations: binary 276 Security considerations: Carries an RPKI Ghostbusters Record 277 [I-D.ietf-sidr-ghostbusters]. 278 Interoperability considerations: None 279 Published specification: This document 280 Applications which use this media type: Any MIME-complaint transport 281 Additional information: 282 Magic number(s): None 283 File extension(s): .gbr 284 Macintosh File Type Code(s): 285 Person & email address to contact for further information: 286 Randy Bush 287 Intended usage: COMMON 288 Author/Change controller: Randy Bush 290 9.
