On the Security of 3GPP Networks [PDF]
, 2000 Later this year we shall see the release of the Third Generation Partnership Project (3GPP) specifications for WCDMA - the first third generation standard for mobile communications. This 3G system combines elements of both a radical departure and a timid evolution from the 2G system known as GSM. It is radically different from GSM in having a wide-band
