Each line is a link to the TS (or TR) description, which points to the "3GPP specification detail" page that gives access to MS Word versions (as zip files, possibly including associated files) as well as pdf versions.
The present document contains an example set of algorithms which may be used as the GSM authentication and key generation functions A3 and A8. (It is not mandatory that the particular algorithms specified in this document are used - the A3 and A8 functions are operator-specifiable rather than being fully standardised).
Section 3 (normative) introduces the algorithms and describes their input and output parameters. Section 4 (normative) defines the algorithms. Section 5 (informative) describes an alternative algorithm that some operators may prefer. Section 6 (informative) provides test data.
The present document contains an example algorithm which may be used as the VSTK key generation function A8_V as described in TS 43.020. (It is not mandatory that the particular algorithm specified in this document is used - the A8_V function is operator-specifiable rather than being fully standardised.)
Clause 4 introduces the algorithm and describes the input and output parameters. Clause 5 defines the algorithm. Clause 6 provides test data.
This Technical Report has been prepared by the ETSI SAGE GSM A5/3 Task Force, and gives a detailed report on the design and evaluation of the A5/3 encryption algorithms for GSM and ECSD, and of the GEA3 encryption algorithm for GPRS (including EGPRS).
