27、GPP systems. In particular, the present document defines the test data: - for the Keccak permutation used within Tuak, - for the authentication algorithms f1 and f1*, - for the algorithms f2, f3, f4, f5 and f5*. 2 References The following documents contain provisions which, through reference in this

28、 text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.

(For f1* this input is more precisely called SQNMS.) See informative Annex C of 1 for methods of encodin

40、g sequence numbers. 4 Preliminary information 4.1 Introduction Within the security architecture of the 3GPP system there are seven security functions f1, f1*, f2, f3, f4, f5 and f5*. The operation of these functions falls within the domain of one operator, and the functions are therefore to be speci

41、fied by each operator rather than being fully standardized. The algorithms specified in this document are examples that may be used by an operator who does not wish to design his own. The inputs and outputs of all seven algorithms are defined in clause4.4 . 4.2 Radix Unless stated otherwise, all tes

42、t data values presented in the present document are in hexadecimal. 4.3 Bit/Byte ordering for Tuak inputs and outputs 3GPP TS 33.102 1 includes the following convention. (There is similar text in the specification of MILENAGE, as defined in 3GPP TS 35.206 2): All data variables in the presentdocumen

43、t are presented with the most significant substring on the left hand side and the least significant substring on the right hand side. A substring may be a bit, byte or other arbitrary length bit string. Where a variable is broken down into a number of substrings, the left-most (most significant) sub

44、string is numbered 0, the next most significant is numbered 1, and so on through to the least significant. So, for example, RAND0 is the most-significant bit of RAND and RAND127 is the least significant bit of RAND. This convention applies to all inputs and outputs to Tuak, as listed in tables 1 to

45、9 below. However, when describing intermediate states of Tuak (e.g. inputs and outputs for the Keccak permutation), variables are simply treated as indexed bit strings. These bit strings will be presented in hexadecimal notation, using a display convention described in clause 5.2. 4.4 Tuak inputs an

46、d outputs The inputs to Tuak are given in tables 1 and 2, the outputs in tables 3 to 9 below. ETSI ETSI TS 135 232 V15.0.0 (2018-07)73GPP TS 35.232 version 15.0.0 Release 15There are a few differences from the inputs and outputs to MILENAGE 2. The key K may be 128 bits or 256 bits. MAC-A and MAC-S m

47、ay be 64, 128 or 256 bits. RES may be 32, 64, 128 or 256 bits. CK and IK may be 128 or 256 bits. Existing 3GPP specifications (see 1 and 5) do not support all these possibilities, but they are included in Tuak for future flexibility in case future releases of these specifications support them. NOTE

48、1: The 3G security architecture specification 1 calls the output of the f1 function MAC while the present document and 2 call it MAC-A. Any sizes for the parameters K, MAC-A, MAC-S, RES, CK and IK mentioned in the present document shall not be supported nor used in entities defined in 3GPP specifica

49、tions until these specifications explicitly allow their use. In any particular implementation, the parameters shall have a fixed length, chosen in advance. For example an operator may fix K at length 256 bits, RES at length 64 bits, CK and IK at length 128 bits. As the lengths do not vary with input, they are not specified as formal input parameters.
