Foreword This Techni
18、cal Specification (TS) has been produced by ETSI Technical Committee TETRA and Critical Communications Evolution (TCCE). The present document is part 2 of a multi-part deliverable covering Rules for the management of the TETRA standard encryption algorithms, as identified below: Part 1: “TEA1“; Part
19、 2: “TEA2“; Part 3: “TEA3“; Part 4: “TEA4“. ETSI ETSI TS 101 053-2 V2.3.1 (2014-04)61 Scope The purpose of the present document is to specify the rules for the management of the TETRA standard encryption algorithm TEA2. This algorithm is intended for air interface encryption in TETRA products. The s
20、pecification for TEA2 consists of the following three parts: Part 1: Algorithm specification; Part 2: Design conformance test data; Part 3: Algorithm input/output test data. The procedures described in the present document apply to licensing organizations to manufacture, possess, install, repair, ho
21、ld, use and destroy equipment and components containing the TEA2 algorithm and to delivering parts 1, 2 and 3 of the TEA2 specifications. Parts 1 and 2 of the specification are confidential. Part 3 of the specification is not confidential and can be obtained directly from the TEA2 Custodian (see cla
22、use 7.2). There are no restrictions on the distribution of this part of the specification. The management structure is defined in clause 4. This structure is defined in terms of the principals involved in the management of TEA2 (ETSI, ETSI Technical Committee TETRA and Critical Communications Evolut
23、ion, TEA2 Custodian and approved recipients) together with the relationships and interactions between them. Clause 5 is concerned with the rules for the use of TEA2. This clause is supplemented by annex H, which provides an exemplary list of the states and territories in which a User may become an a
24、pproved recipient. Clause 6 describes the types of licence that may be requested. The procedures for delivering TEA2 specifications to approved recipients are defined in clause 7. This clause is supplemented by annex A, which specifies the items that are to be delivered. Clause 8 is concerned with t
25、he criteria for approving an organization for receipt of TEA2 deliverables and with the responsibilities of an approved recipient. This clause is supplemented by annexes B to G which contain the Confidentiality and Restricted Usage Undertakings to be signed by the TEA2 Custodian and approved recipie
26、nts of TEA2 specifications and/or equipment and components containing TEA2. Clause 9 is concerned with the appointment and responsibilities of the TEA2 Custodian. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

41、 of TEA2 and the relationships and interactions between them: ETSI is the owner of the TEA2. ETSI Technical Committee TETRA and Critical Communications Evolution sets the approval criteria for receipt of the algorithm (see clause 8). The TEA2 Custodian is the interface between ETSI and the recipient
42、s of TEA2 licences and specifications. ETSI ETSI TS 101 053-2 V2.3.1 (2014-04)9 The TEA2 Custodian is as identified in clause 9.2 of the present document. The TEA2 Custodians duties are detailed in clause 9. They include distributing signed TEA2 Confidentiality and Restricted Usage Undertakings (CRU
43、Us) and, if appropriate, specifications to approved recipients, as detailed in clauses 7 and 8, providing limited technical advice to approved recipients and providing algorithm status reports to ETSI Technical Committee TETRA and Critical Communications Evolution. NOTE: A CRUU signed by both the TE
44、A2 Custodian and applicant constitutes a licence to hold or use TETRA subscriber and fixed network equipment and components containing TEA2. The form of CRUU exchanged is summarized in figure 2.

45、y Users of TEA2 A TEA2 Primary and Secondary User Licence is given to a governmental organization for a TETRA network that is primarily used by public safety organizations (see note 1) in their own state or territory. A TETRA network may consist of fixed base stations and SwMI, all located in the ho
46、me state or territory, and/or one or more base stations and SwMIs that may also be used outside the home state or territory if both base stations and SwMIs are controlled from the home state or territory. A governmental organization that obtains a TEA2 User Licence under these conditions is referred
47、 to as a primary user of TEA2. The Confidentiality and Restricted Usage Undertaking (CRUU) in annex E applies to primary and secondary users (see note 2). The TEA2 licence is required for the use of TEA2 in any element of the TETRA network including TETRA Subscriber equipment (TETRA Mobile Station (
48、MS) where air interface encryption as defined in EN 300 392-7 i.1 or ETS 300 396-6 i.2 is applied. NOTE 1: Public safety organizations are e.g. Police, Fire brigade, Customs and Excise, Ambulance and Emergency Medical Service, Coastguard. NOTE 2: There may be more than one primary user in any allowe
49、d state and the number of primary users is a national option. ETSI ETSI TS 101 053-2 V2.3.1 (2014-04)10It is to be decided by the primary user of TEA2, who has received a TEA2 User Licence from the TEA2 Custodian, which user organizations can use the above-mentioned network. This may be done on the basis of a sublicensing procedure that may also be needed for the procurement of mobile terminals or movable equipment by a user or user organization. An organization that obtains a TEA2 End User Licence under these conditions is referred to as an end user
