TLDR
Two new conference key distribution schemes for digital mobile communication systems are presented, in which a group of users can generate a common secret keg over a public channel so that they may hold a secure conference.Abstract:
We propose a new service for digital mobile communication systems. The service enables two or more users to hold a secure conference. Two requirements must be considered: privacy and authentication. Privacy involves ensuring that an eavesdropper cannot intercept the conversations of the parties holding the conference. Authentication involves ensuring that service is not obtained fraudulently in order to avoid usage charges. We present two new conference key distribution schemes for digital mobile communication systems. In these schemes, a group of users can generate a common secret keg over a public channel so that they may hold a secure conference. >read more

A Quick Group Key Distribution Scheme with Entity Revocation
TL;DR: A novel key distribution scheme with “entity revocation” that makes frequent key distribution a practical reality and uses a technique similar to “threshold cryptosystems” and the one-pass Diffie-Hellman key exchange scheme.

A self-encryption mechanism for authentication of roaming and teleconference services
Kuo-Feng Hwang,Chin-Chen Chang +1 more
TL;DR: The idea behind the proposed technique is to introduce a simple mechanism which is called "self-encryption" and it is suggested that this mechanism can be easily adopted as the authentication function for the secure teleconference service.

Extension of authentication protocol for GSM
TL;DR: The merit of the proposed protocol is that it does not cause problems and alter the existing architecture of GSM at all, and the robustness of the new protocol is also based on security algorithms A3, A5 and A8.

TL;DR: The goal of this book is to introduce the mathematical principles of data security and to show how these principles apply to operating systems, database systems, and computer networks.
Digitalized signatures and public-key functions as intractable as factorization
TL;DR: It is proved that for any given n, if the authors can invert the function y = E (x1) for even a small percentage of the values y then they can factor n, which seems to be the first proved result of this kind.
