A Security Framework for Wireless Sensor Networks Utilizing a Unique Session Key

Key management is a core mechanism to ensure the security of applications and network services in wireless sensor networks. It includes two aspects: key distribution and key revocation. Many key management protocols have been specifically designed for wireless sensor networks. However, most of the key management protocols focus on the establishment of the required keys or the removal of the compromised keys. The design of these key management protocols does not consider the support of higher level security applications. When the applications are integrated later in sensor networks, new mechanisms must be designed. In this paper, we propose a security framework, uKeying, for wireless sensor networks. This framework can be easily extended to support many security applications. It includes three components: a security mechanism to provide secrecy for communications in sensor networks, an efficient session key distribution scheme, and a centralized key revocation scheme. The proposed framework does not depend on a specific key distribution scheme and can be used to support many security applications, such as secure group communications. Our analysis shows that the framework is secure, efficient, and extensible. The simulation and results also reveal for the first time that a centralized key revocation scheme can also attain a high efficiency.

RP96-11 The Farm Corporation: What It Is, How It Works, How It Is Taxed

A corporation is an artificial person that is created and operated according to state corporation statutes. It is a separate taxpayer subject to specific and detailed federal, state, and local tax laws. The advice and service of your lawyer are indispensable in organizing and operating a farm corporation. There are three basic forms of farm business organization, the sole proprietorship, the partnership, and the corporation. Variations of these forms have resulted in the limited partnership and the "tax option" corporation. These three basic forms are discussed in this research publication.

EC77-865 Have It Your Way By Making A Will

Making a will is not the sad and gloomy picture painted by some people. Quite the contrary! A person who makes a will is creating his or her own blueprint for the future. A will, like life insurance, social security, or retirement plans, provides security and peace of mind. The person who has a will made can rest assured that property and loved ones will be taken care of precisely in the manner he or she desires. This publication presents basic information about wills, one of the most important documents a person can make or possess. This information can be useful both to those who have already made a will and those who have not.
