Cryptanalysis of anonymous channel protocol for large-scale area in wireless communications
The authentication and anonymous channel protocol for large-scale area in wireless communications proposed in [Proc. Sixth IEEE Symposium on Computers and Communications (ISCC01), 35 (2001) 36] by LinJan is analyzed, proving that it is not secure. More precisely, fake anonymous channel tickets can be easily generated allowing non-authorized users to be validated by the Visiting Network. Unlike it was claimed in [Proc. Sixth IEEE Symposium on Computers and Communications (ISCC01), 35 (2001) 36], the security of this protocol does not rely on the difficulty of computing discrete logarithms over the finite field GF(p), p being a prime.
