ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / This paper presents the design for secure IP multicasting in an iNet environment using public key cryptography. Morgan State University has been conducting research to improve the telemetry network by improving network performance, implementing IP (Internet Protocol) multicasting and providing a stronger security system for the iNet environment. The present study describes how IP multicasting could be implemented to provide more secure communication in the iNet environment by reducing traffic and optimizing network performance. The multicast of data is closely tied to the key management center for secure applications. This paper develops a means of delivering keys between two or more parties showing a relationship between the multicast network and the Key Management Center (KMC). The KMC is an element of the system which distributes and manages session keys among multicast members. A public key encryption method is used to address the distribution of session keys in the multicast network. The paper will present a system level design of multicast and key management with dual encryption of session keys for the iNet system.

Cryptography fascinates people of all generations and is increasingly presented as an example for the relevance and application of the mathematical sciences. Indeed, many principles of modern cryptography can be described at a secondary school level. In this context, the mathematical background is often only sparingly shown. In the worst case, giving mathematics this character of a tool reduces the application of mathematical insights to the message ”cryptography contains math”. This paper examines the question as to what else cryptography can offer to mathematics education. Using the RSA cryptosystem and related content, specific mathematical competencies are highlighted that complement standard teaching, can be taught with cryptography as an example, and extend and deepen key mathematical concepts.
