Introduction The present documenthas been prepared by the 3GPP Task Force, and gives a detailed specification of the 3GPP integrity algorithm GIA4. The present document is the second of three, which b
22、etween 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 Aspects; Specification of the GIA4 integrity algorithms for GPRS; GIA4 specification“. - 3GPP TS 55.242: “3rd Gener
23、ation Partnership Project; Technical Specification Group Services and System Aspects; Specification of the GIA4 integrity algorithms for GPRS; Implementers test data“. - 3GPP TS 55.243: “3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Specification of t
24、he GIA4 integrity algorithms for GPRS; Design conformance test data“. ETSI ETSI TS 155 242 V15.0.0 (2018-07)53GPP TS 55.242 version 15.0.0 Release 151 Scope The present document defines the implementers test data of the 3GPP integrity algorithm GIA4. 2 References The following documents contain prov
25、isions which, through reference in this 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
26、 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 that document in the same Release as the present document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 3
27、GPP 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 document, the terms and definitions given in 3GPP TR 21.905 1 and the following apply. A term defined in the present document
28、 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 21.905 1 and the following apply. An abbreviation defined in the present document takes precedence over the definition o
29、f 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 a given input message using integrity key KI128. The approach adopted uses KASUMI 2 in a form of CBC-MAC mode. 4.2 Not
30、ation 4.2.1 Radix “0x“ is used to indicate hexadecimal numbers. 4.2.2 Conventions The assignment operator “=“, is used as in several programming languages. The following: = ETSI ETSI TS 155 242 V15.0.0 (2018-07)63GPP TS 55.242 version 15.0.0 Release 15means that assumes the value that had before the
31、 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 in this specification are presented with the most significant bit (or byte) on the left hand side and the least significant bit (or b
32、yte) 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 significant is numbered 1 and so on through to the least significant. For example an n-bit MESSAGE is subdivided into 64-bit substrings

35、ariables A, B are 64-bit registers that are used within the function to hold intermediate values. BLOCKS an integer variable indicating the number of successive applications of KASUMI that need to be performed. CONSTANT-F a 32-bit parameter which is constant for any given FRAMETYPE input. DIRECTION
36、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 time variant input to the function. KI128 the 128-bit integrity key. KM a 128-bit constant that is used to modify a key
37、. 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. MESSAGE the input octet stream of length M octets that is to be processed by the function. PS is the input padded string proce
38、ssed by the function. ETSI ETSI TS 155 242 V15.0.0 (2018-07)73GPP TS 55.242 version 15.0.0 Release 155 Test data This clause only available under licence.
