The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will
18、be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the sec
19、ond digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The present document has been prepared by the 3GPP Task Force, and gives a
20、detailed specification of the 3GPP integrity algorithm GIA4. The present document is the third of three, which between them form the entire specification of the 3GPP Integrity Algorithm GIA4: - 3GPP TS 55.241: “3rd Generation Partnership Project; Technical Specification Group Services and System Asp
21、ects; Specification of the GIA4 integrity algorithms for GPRS; GIA4 specification“. - 3GPP TS 55.242: “3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Specification of the GIA4 integrity algorithms for GPRS; Implementers test data“. - 3GPP TS 55.243: “3
22、rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Specification of the GIA4 integrity algorithms for GPRS; Design conformance test data“. ETSI ETSI TS 155 243 V14.0.0 (2017-04)53GPP TS 55.243 version 14.0.0 Release 141 Scope The present document defines th
23、e Design conformance test data for the 3GPP integrity algorithm GIA4. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, ver
24、sion number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of
25、 that document in the same Release as the present document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 3GPP TS 55.241: “Specification of the GIA4 encryption algorithms for GPRS; GIA4 specification“. 3 Definitions and abbreviations 3.1 Definitions For the purposes of the present docume
26、nt, the terms and definitions given in 3GPP TR 21.905 1 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 1. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in 3GPP TR 2
27、1.905 1 and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in 3GPP TR 21.905 1. 4 Introductory information 4.1 Introduction The integrity algorithm GIA4 computes a 32-bit MAC (Message Authentication Code) of
28、 a given input message using integrity key KI128. The approach adopted uses KASUMI 2 in a form of CBC-MAC mode. 4.2 Notation 4.2.1 Radix The prefix “0x“ is used to indicate hexadecimal numbers. ETSI ETSI TS 155 243 V14.0.0 (2017-04)63GPP TS 55.243 version 14.0.0 Release 144.2.2 Conventions The assig
29、nment operator “=“, is used as in several programming languages. So the following: = means that assumes the value that had before the assignment took place. For instance: x = x + y + 3 means: (new value of x) becomes (old value of x) + (old value of y) + 3. 4.2.3 Bit/Byte ordering All data variables
30、 in the present document are presented with the most significant bit (or byte) on the left hand side and the least significant bit (or byte) on the right hand side. Where a variable is broken down into a number of sub-strings, the left most (most significant) sub-string is numbered 0, the next most
31、significant is numbered 1 and so on through to the least significant. For example an n-bit MESSAGE is subdivided into 64-bit substrings MB0,MB1MBiso for the following message: 0x0123456789ABCDEFFEDCBA987654321086545381AB594FC28786404C50A37 MB0= 0x0123456789ABCDEF MB1= 0xFEDCBA9876543210 MB2= 0x86545

BLOCKS an integer variable indicating the number of successive applications of KASUMI
34、 that need to be performed. CONSTANT-F a 32-bit parameter which is constant for any given FRAMETYPE input. DIRECTION a 1-bit input indicating the direction of transmission (uplink or downlink). FRAMETYPE an 8-bit input to the function indicating the type of frame to be protected. INPUT-I a 32-bit ti
35、me variant input to the function. KI128 the 128-bit integrity key. KM a 128-bit constant that is used to modify a key. M an input to the function which specifies the number of octets of message to be MACd (1-65536). MAC the 32-bit message authentication code (MAC) produced by the function. ETSI ETSI
