Test GSM/GPRS/EGPRS Mobile Device Performance with Ciphering
The E6705A Encryption software is an extension to the E6701F/E6704A lab application software that provides GSM/GPRS/EGPRS encryption functionality. It enables the GSM encryption algorithms A5/1 and A5/3, along with GPRS encryption algorithms.
With ciphering enabled, raw data and the Ciphering Key(Kc) are used as the input to the Ciphering Algorithm. The resultant data is transmitted over the air interface and decrypted using the same algorithm and ciphering key at the other end.
Selectable ciphering algorithms supported:
- GPRS GEA1
- GPRS GEA2
- GPRS GEA3
- GSM A5/1
- GSM A5/3
The software includes a settable T3360 GMM Authentication and Ciphering response timer, and T3260 MM Authentication response timer. It has automatic default support for the Agilent test uSIM, and manual entry of Kc, RAND and SRES for other uSIM types.
