ABSTRACT:
A HRPD network access authentication method based on CAVE algorithm is proposed. An AT generates a random number “RAND” necessary for the calculation of AUTH1 by using the “Random text” included in the CHAP Challenge message. A UIM card works out the AUTH1 by using the random number “RAND” and the SSD_A in the UIM card. The AT carries the AUTH1 by the Result field of the CHAP Response message. The AN-AAA generates the random number “RAND” necessary for the calculation of AUTH2 by using the “Random text” included in the Radius Access Request message. The AN-AAA works out the AUTH2 by using the random number “RAND”. The two results AUTH1 and AUTH2 is compared. If they are just the same, the authentication on the AT passes. Otherwise, the AT is rejected to access.
