ETSI ETSI TS 101 052 V2.1.1 (2016-02)5 1 Scope The purpose of the present document is to specify the rules for the ma
16、nagement of the TETRA standard authentication and key management algorithm set TAA1. This algorithm set is intended for air interface security in TETRA products. The specification for TAA1 consists of the following three parts: Part 1: Algorithm specification; Part 2: Design conformance test data; P
17、art 3: Algorithm input/output test data. The procedures described in the present document apply to Parts 1 and 2 of the specifications. Parts 1 and 2 are confidential for each of the algorithms. Part 3 of each of the specifications is not confidential and can be obtained directly from the TAA1 Custo
18、dian (see clause 5.2). There are no restrictions on the distribution of this part of the specifications. The management structure is defined in clause 4. This structure is defined in terms of the principals involved in the management of TAA1 (ETSI, ETSI Technical Committee TCCE, TAA1 Custodian and a
19、pproved recipients) together with the relationships and interactions between them. The procedures for delivering TAA1 to approved recipients are defined in clause 5. This clause is supplemented by annex A which specifies the items which are to be delivered. Clause 6 is concerned with the criteria fo
20、r approving an organization for receipt of TAA1 and with the responsibilities of an approved recipient. This clause is supplemented by annex B which contains a Confidentiality and Restricted Usage Undertaking to be signed by each approved recipient. Clause 7 is concerned with the appointment and res
21、ponsibilities of the TAA1 Custodian. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

29、egister 7 = Document filing 8 = Technical advice Figure 1: TAA1 management structure Figure 1 shows the three principals involved in the management of TAA1 and the relationships and interactions between them. ETSI is the owner of TAA1. The ETSI Secretariat together with ETSI TC TCCE sets the approva
30、l criteria for receipt of the algorithm (see clause 6). The TAA1 Custodian is the interface between ETSI and the approved recipients of TAA1. The Custodian shall be the ETSI Secretariat unless it is decided by ETSI Secretariat and/or ETSI TC TCCE to (temporarily) delegate this task to a third party
31、on the basis of an agreement between the latter and the ETSI Secretariat. The TAA1 Custodians duties are detailed in clause 7. They include distributing TAA1 to approved recipients, as detailed in clause 5, providing limited technical advice to approved recipients and providing algorithm status repo
32、rts to ETSI TC TCCE.

33、is clause describes the procedure for the distribution of parts 1, 2 and 3 of the TAA1 specification (see clause 1) when requested together. See clause 5.2 for the procedure for the distribution of part 3 as a separate item. The TAA1 Custodian is responsible for determining whether an applicant meet
34、s the criteria to receive the TAA1 specification. The TAA1 Custodian is responsible for signing TAA1 Confidentiality and Restricted Usage Undertakings with qualified applicants who require access to the TAA1 specification. The TAA1 Custodian is responsible for sending copies of the TAA1 specificatio
35、n to qualified applicants. The following procedure for distributing TAA1 specifications is defined with reference to figure 1. 1) The TAA1 Custodian receives a written request for N copies of the TAA1 specification parts 1, 2 and 3 (see notes 1 and 2). 2) The TAA1 Custodian determines whether the re
36、questing organization meets the approval criteria (see clause 6). 3) If the request is not approved, the TAA1 Custodian informs the requesting organization that its request has not been approved. 4) If the request is approved, the TAA1 Custodian dispatches 2 copies of the corresponding Confidentiali
37、ty and Restricted Usage Undertaking (as given in annex B) for signature by the approved recipient (see notes 2 and 6) together with a copy of the present document (Rules for the management of the TETRA standard authentication and key management algorithm set TAA1). 5) Both copies of the Confidential
38、ity and Restricted Usage Undertaking (CRUU) have to be signed by the approved recipient (see notes 5 and 7) and returned to the TAA1 Custodian, together with the payment of any applicable charges. 6) The TAA1 Custodian sends up to N (see note 3) numbered copies of the TAA1 specification parts 1, 2 a
39、nd 3 to the approved recipient, together with one countersigned copy of the returned Confidentiality and Restricted Usage Undertaking (CRUU) and a covering letter (see notes 4 and 6). 7) The TAA1 Custodian updates the TAA1 Register by recording the name and address of the recipient, the numbers of t
40、he copies of the TAA1 specification delivered and the date of delivery. If the original request is not approved, the TAA1 Custodian records the name and address of the requesting organization and the reason for rejecting the request in the TAA1 Register (see also note 8). 8) The TAA1 Custodian count
41、ersigns and files the second returned copy of the Confidentiality and Restricted Usage Undertaking (CRUU) in the TAA1 File together with a copy of the covering letter sent to the approved recipient. 9) The TAA1 Custodian may provide very limited technical advice with respect to answering questions c
42、oncerning the TAA1 specification. 10) If there is a change in the contact details of the signatory or name or ownership of the organization, the organization shall inform the TAA1 Custodian. 11) All copies of the TAA1 specification shall be returned to the TAA1 Custodian when they are no longer requ
43、ired by the organization that received them (see note 8). NOTE 1: Requests for the TAA1 specification may be made directly to the TAA1 Custodian or through ETSI. NOTE 2: The Confidentiality and Restricted Usage Undertaking (CRUU) specifies the number of copies requested. NOTE 3: The covering letter
44、specifies the numbers of the copies delivered. ETSI ETSI TS 101 052 V2.1.1 (2016-02)9 NOTE 4: If the request is approved, the TAA1 Custodian sends all items listed in annex A. Requests for part of the package of items are rejected. NOTE 5: An organization may request the specification on behalf of a
45、 second organization to which it is subcontracting work which requires the specification. In this case, the first organization is responsible for returning a Confidentiality and Restricted Usage Undertaking (CRUU) signed by the second organization. NOTE 6: Under normal circumstances the TAA1 Custodi
46、an is expected to respond within 25 working days, excluding the delay of the procedures with the Customs Services. NOTE 7: The approved recipient is represented by its authorized officers. NOTE 8: If a TAA1 specification is returned to the TAA1 Custodian (for example the recipient may decide not to
47、make use of the information), then the TAA1 Custodian destroys the specification and enters a note to this effect in the TAA1 Register. 5.2 Distribution of TAA1 specification part 3 by the TAA1 Custodian The following procedure is defined for distributing only part 3 of the TAA1 specification: 1) Th
48、e TAA1 Custodian receives a written request for one single copy of part 3 of the TAA1 specification. 2) The TAA1 Custodian sends one copy of part 3 of the TAA1 specification to the applicant. 6 Approval criteria and restrictions The approval criteria are set by the ETSI Secretariat together with ETS
49、I TC TCCE and maintained by the TAA1 Custodian. The TAA1 Custodian may recommend changes to these criteria. In order for an organization to be considered an approved recipient of the TAA1 specification it has to satisfy at least one of the following criteria: C1 The organization is a bona fide designer or manufacturer of TETRA subscriber or fixed network equipment, where the algorithm requested is included in the systems. C2 The organization is a bona fide designer or manufacturer of components for TETRA subscriber or fixed network equipment, where at least one of the co
