The purpose of ETSI TS 101 053-2 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 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.
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 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 terms 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 clause 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 clause 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 to 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.
