Section: 6.5.6 UIA identification
Content: Each UMTS Integrity Algorithm (UIA) will be assigned a 4-bit identifier. Currently, the following values have been defined: "00012" : UIA1, Kasumi. "00102" : UIA2, SNOW 3G. The remaining values are not defined. UEs and RNCs shall implement UIA1 and UIA2. The use of Kasumi for the integrity protection function f9 is specified in TS 35.201[ 3G Security; Specification of the 3GPP confidentiality and integrity algorithms; Document 1: f8 and f9 specification ]  [11] and TS 35.202[ 3G Security; Specification of the 3GPP confidentiality and integrity algorithms; Document 2: Kasumi  specification ]  [12]. Implementers' test data and design conformance data is provided in TS 35.203[ 3G Security; Specification of the 3GPP confidentiality and integrity algorithms; Document 3: Implementors' test data ]  [13] and TS 35.204[ 3G Security; Specification of the 3GPP confidentiality and integrity algorithms; Document 4: Design conformance test data ]  [14]. The use of SNOW 3G for the integrity protection function f9 is specified in TS 35.215[ Specification of the 3GPP Confidentiality and Integrity Algorithms UEA2 & UIA2; Document 1: UEA2 and UIA2 specifications ]  [24] and TS 35.216[ Specification of the 3GPP Confidentiality and Integrity Algorithms UEA2 & UIA2; Document 2: SNOW 3G specification ]  [25]. Implementers' test data and design conformance data is provided in TS 35.217[ Specification of the 3GPP Confidentiality and Integrity Algorithms UEA2 & UIA2; Document 3: Implementors' test data ]  [26] and TS 35.218[ Specification of the 3GPP Confidentiality and Integrity Algorithms UEA2 & UIA2; Document 4: Design conformance test data ]  [27].
