3GPP55.252Implementers' test dataRelease 17Specification of the GEA5 encryption and GIA5 integrity algorithms for General Packet Radio Service (GPRS)TS

The present document has been prepared by the 3GPP Task Force, and gives a detailed specification of the 3GPP encryption algorithm GEA5 and integrity algorithm GIA5.

This document is the second of three, which between them form the entire specification of the 3GPP encryption algorithm GEA5 and integrity algorithm GIA5:

– 3GPP TS 55.251: "3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Specification of the GEA5 encryption and GIA5 integrity algorithms for GPRS; GEA5 and GIA5 specification".

– 3GPP TS 55.252: "3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Specification of the GEA5 encryption and GIA5 integrity algorithms for GPRS; Implementers’ test data".

– 3GPP TS 55.253: "3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Specification of the GEA5 encryption and GIA5 integrity algorithms for GPRS; Design conformance test data".
