Abstract

This note describes some cryptographic issues related to multi-located parties. In general, multi-located parties make it difficult for the eavesdropper to mount the man-in-the-middle attack. Conversely, they make it easier to address problems such as joint encryption and error correction coding. It is easier to implement the three-stage quantum cryptography protocol.
