The present document is part 2 of a multi-part deliverable covering Rules for the management of the TETRA standard encryption
21、algorithms, as identified below: Part 1: “TEA1“; Part 2: “TEA2“; Part 3: “TEA3“; Part 4: “TEA4“. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of
22、 the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI TS 101 053-2 V2.4.1 (2018-01)6 1 Scope The purpose of the present document is to specify the rules for the management of
23、 the TETRA standard encryption algorithm TEA2. This algorithm is intended for air interface encryption in TETRA products. The specification 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.
24、 The procedures described in the present document apply to licensing organizations to manufacture, possess, install, repair, hold, 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
25、are confidential. Part 3 of the specification is not confidential and can be obtained directly from the TEA2 Custodian (see clause 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 term
26、s of the principals involved in the management of TEA2 (ETSI, ETSI Technical Committee TETRA and Critical Communications Evolution, 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 cl
27、ause is supplemented by annex H, which provides an exemplary list of the states and territories in which a User may become an approved recipient. Clause 6 describes the types of licence that may be requested. The procedures for delivering TEA2 specifications to approved recipients are defined in cla
28、use 7. This clause is supplemented by annex A, which specifies the items that are to be delivered. Clause 8 is concerned with the 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 t
29、o G which contain the Confidentiality and Restricted Usage Undertakings to be signed by the TEA2 Custodian and approved recipients of TEA2 specifications and/or equipment and components containing TEA2. Clause 9 is concerned with the appointment and responsibilities of the TEA2 Custodian. 2 Referenc

45、n the management 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 a
46、nd the recipients of TEA2 licences and specifications. 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 (CRUUs) and, if appropriate,
47、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 TEA2 Custodian and applican
48、t 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.
