ETSI ETSI TS 133 105 V13.0.0 (2016-01)63GPP TS 33.105 version 13.0.0 Release 131 Scope This specification constitutes a requirements specification for the security functions which may be used to provide the network access security features defined in 1
28、. The specification covers the intended use of the functions, the technical requirements on the functions and the requirements as regards standardization. For those functions that require standardization, it also covers the intended use of the algorithm specification, the requirements on test data,
29、and quality assurance requirements on both the algorithm and its documentation. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

Data origin authentication: The corroboration that the source of data received is as claimed. Entity authentication: The provision
34、 of assurance of the claimed identity of an entity. Key freshness: A key is fresh if it can be guaranteed to be new, as opposed to an old key being reused through actions of either an adversary or authorised party.

A substring may be a bit, byte or other arbitrary le

42、General algorithm requirements 4.1 Resilience The functions should be designed with a view to its continued use for a period of at least 20 years. Successful attacks with a work load significantly less than exhaustive key search through the effective key space should be impossible. The designers of
43、above functions should design algorithms to a strength that reflects the above qualitative requirements. 4.2 World-wide availability and use Legal restrictions on the use or export of equipment containing cryptographic functions may prevent the use of such equipment in certain countries. It is the i
44、ntention that UE and USIMs which embody such algorithms should be free from restrictions on export or use, in order to allow the free circulation of 3G terminals. Network equipment, including RNC and AuC, may be expected to come under more stringent restrictions. It is the intention is that RNC and
45、AuC which embody such algorithms should be exportable under the conditions of the Wassenaar Arrangement 2. 5 Functional algorithm requirements 5.1 Authentication and key agreement 5.1.1 Overview The mechanism for authentication and key agreement described in clause 6.3 of 1 requires the following cr
46、yptographic functions: f0 the random challenge generating function; f1 the network authentication function; f1* the re-synchronisation message authentication function; f2 the user authentication function; f3 the cipher key derivation function; f4 the integrity key derivation function; f5 the anonymi
47、ty key derivation function for normal operation; f5* the anonymity key derivation function for re-synchronisation. 5.1.1.1 Generation of quintets in the AuC To generate a quintet the HLR/AuC: - computes a message authentication code for authentication MAC-A = f1K(SQN | RAND | AMF), an expected respo
48、nse XRES = f2K(RAND), a cipher key CK = f3K(RAND) and an integrity key IK = f4K(RAND) where f4 is a key generating function. - If SQN is to be concealed, in addition the HLR/AuC computes an anonymity key AK = f5K(RAND) and computes the concealed sequence number SQN AK = SQN xor AK. Concealment of th
49、e sequence number is optional. - Finally, the HLR/AuC assembles the authentication token AUTN = SQN AK | AMF | MAC-A and the quintet Q = (RAND, XRES, CK, IK, AUTN).
