  • Adaptive algorithms for reducing PCS Network Authentication traffic
    IEEE Transactions on Vehicular Technology, 1997
    Co-Authors: Seshadri Mohan, Nelson Ray Sollenberger, H. Sherry
    Abstract:

    Two Authentication schemes (ASs) have been proposed in the Electronic Industry Association/Telecommunications Industry Association's (EIA/TIA) Telecommunications Systems Bulletins (TSBs) 51 for incorporation in the cellular industry Interim Standard IS 41 Revision C. In the first scheme, which we refer to as the WS scheme, a unique secret key [also known as shared secret data (SSD)] is shared only between the Authentication center (AC) and handset. In the second scheme, referred to as the S scheme, the SSD is also shared with the visited system. The performance of the two schemes can be compared by using the expected number of call originations/terminations between two consecutive registrations or call-to-mobility ratio (CMR). Based on the message flow (accesses to databases), it is apparent that the S scheme outperforms the WS schemes if the CMR ratio is large. The CMRs of users will likely span a wide range and, even for the same user, will perhaps vary from time to time. It is therefore desirable to switch between the ASs based on the users' CMR to reduce the signaling Network traffic. We propose two adaptive algorithms to determine how and when to switch between the ASs for a given user. Our performance study indicates that as the CMR of a user changes, the adaptive algorithms automatically select the best AS in real time.

  • ACSAC - Network Authentication tokens
    [1989 Proceedings] Fifth Annual Computer Security Applications Conference, 1
    Co-Authors: R. Davis
    Abstract:

    Network users may be authenticated by different means and from a variety of locations. Once authenticated, the user's access should be consistent with the strength of the Authentication. The author examines one possible method for determining the Authentication strength and conveying this information within a distributed Network. The approach discussed uses a token composed of a unique user ID and an Authentication level. The token is sent along with the request for establishing a remote session. Once the token is received, the remote location determines user access based solely on the Authentication token. >
