Abstract or Summary:
In the modern crypto-world authentic communication channels are created from an authentically pre-shared public key before information can reliably be transfered. This poster paper proposes to discuss the merits of using a person's voice as pre-shared token to establish the public key for message authentication. The challenges include reliably verifying a known voice in the light of factors such as various conversion and compression aspects as well as malicious attacks on the system such as spoofed voices.
