EVDO Security

    Broadband over CDMA networks ala EVDO sounds like a really cool
    technology but I'm wondering about the security implications. I did a
    google search but didn't find any definitive answers.

    Does EVDO have robust encryption built into the protocol or would I be
    broadcasting in the clear? How, other than a VPN/Proxy setup, could I
    secure such a connection?

    Thanks!

  2. Try '1xrtt security' on Google - 1xRTT is the precursor to EVDO - the
    underlying CDMA security will be the same. Your carrier should also be able
    to provide data.

    My investigation lead our organisation to believe their are few intrinsic
    security problems in using EVDO. What concerns me though is the plethora of
    insecure devices using this technology - they are often in an 'always on'
    state, use bluetooth, and users being what they are they contain cached
    passwords. This combined with the fact that they are often executive toys
    means that the loss or theft of these devices may lead to access to email
    and possibly other data of the most sensitive kind.

    We use them for roaming users with laptops where the security can be locked
    down much better.
