Abstract
Methods described herein relate to identifying an audio rogue base station intercept of a call using a modified distance bounding algorithm. Methods may include: establishing a shared resource for a session with a remote end device; selecting a nonce and provide the nonce to the remote end device; generating a sequence of bits; dividing the sequence of bits into a predetermined number of sub-sequences; performing a bit exchange with the remote end device using dual tone multi-frequency (DTMF) tones; determining, from the bit exchange, an average time of transmission; and identifying the presence or absence of an adversary intercepting the session.
