As our economy and critical infrastructure increasingly rely on the Internet, securing routing protocols becomes of critical importance. In this paper, we present four new mechanisms as tools for securing distance vector and path vector routing protocols. For securing distance vector protocols, our hash tree chain mechanism forces a router to increase the distance (metric) when forwarding a rou...

Banana is a key staple and cash crop in east and central Africa. However, the recent outbreak of Banana Xanthomonas wilt (BXW) has threatened farmers whose livelihoods depend on the crop. Since 2002, stakeholders embarked on campaigns to sensitize farmers on the disease and its management. This study evaluated the effectiveness of these efforts by examining farmers’ awareness of the disease, co...

The free distribution of seeds and tools is the standard approach to agricultural recovery. The predominance of this approach is partly attributable to the: (1) perception that farmer seed quality is poor, (2) insistence on seed certification, (3) promotion of researcher varieties, (4) misdiagnosis of unavailability, (5) difficulty accessing farmer seed, and (6) support for the commercial seed ...

Common belief and some empirical evidence indicates that productivity of a farmer may increase with age, reach some maximum level, and then decrease with further age (Tauer 1984; Tauer 1995). If productivity exhibits a life-cycle pattern, then productivity of agriculture may decrease as the U.S. farm population continues to age. Lifecycle changes are also critical in planning for succession of ...

This paper presents securing satellite communications using link level security (such as ATM security) or network level security (such as IPSEC), where both can be applied to military satellite communications. The paper examines the topic of securing very large multicast groups over satellites, where the group size and group dynamics have great impact on networks performance and network security.
