Cryptography for Multi-Located Parties
Source: Cornell University
This note is to describe issues and problems related to cryptography for a network of distributed, multi-located parties. Given that many business and government entities have secure links between their own geographically distributed computers, multi-location is already a fact for many users. Multi-located parties can address the problem of man-in-the-middle attack, much more easily without the need for a certification authority. The existence of multiple links between sender and receiver also make it easier to implement joint encryption and error correction coding secure communication with side information as in watermarking as well as the implementation of three-stage protocol for quantum cryptography.
