  3. Need for authentication classification Three major criteria for classification • To interpret the similarities between sets of related protocols • To understand the motivation behind each • To better analyze and compare protocols with respect to their encapsulating class rather than individual protocols • To identify common vulnerabilities and attacks against each class of authentication protocols • To identify common architectural elements in each class • A node’s role in the authentication for classification • Type of credentials used for authentication • Phase during which the establishment of credentials take place Introduction 1.

  10. Need for authentication management Factors that affect the performance of the authentication operation • Enhanced performance • Interoperability in today’s networks • A) The network traffic load • B) The number of authentication servers • C) Servers’ placement Authentication Management Architecture 5. Authentication Management Architecture 10 SALAB at KAIST

  11. Simulation environment • 10x10 grid of nodes • 20, 40, 60, 80 100, 150, and 200 UDP flows (for A) • Before a flow starts, the source and destination nodes should authenticate on another through an authentication server • 1,2,3, and 4 authentication servers (for B) • Two placement model (for C) Authentication Management Architecture 5.

  18. Authentication Management Architecture 5.5 Hierarchical deployment model 18 Trade off between security and performance SALAB at KAIST

  19. Summary • A generic authentication process • A taxonomy of authentication protocols • Counterintuitive increase in delay as the number of authentication severs increases for a high number of flows • -> highlighting the need for authentication management • Discussion • Taxonomy in ad hoc network? • Meaning of ‘management’ and ‘interoperability’ ? • Need for specific simulation explanation • How about expending 10X10 topology to broader scale? Conclusion 6. Conclusion 19 SALAB at KAIST
