Section: 6.6.6 UEA identification
Content: Each UEA will be assigned a 4-bit identifier. Currently the following values have been defined: "00002" : UEA0, no encryption. "00012" : UEA1, Kasumi. "00102" : UEA2, SNOW 3G. The remaining values are not defined. UEs shall implement UEA0, UEA1 and UEA2. The use of Kasumi for the ciphering function f8 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 ciphering function f8 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].
