IPSec (Internet Protocol Security)
Ankit Agarwal, Nikhil Mittal · 2002
Information is the new currency of the global economy. We increasingly rely on the electronic creation, storage, and transmittal of personal, financial, and other confidential information, and demand the highest security for all these transactions. We require complete access to time-sensitive data, regardless of physical location. We expect devices -- personal digital assistants, mobile phones, office PCs and home entertainment systems -- to access that information and work together in one seamless, integrated system. Pervasive computing can help us manage information quickly, efficiently, and effortlesslyPervasive computing provides an attractive vision for the future of computing. Computational power will be available everywhere. Mobile and stationary devices will dynamically connect and coordinate to seamlessly help users in accomplishing their tasks. However, for this vision to become a reality, developers must build applications that constantly adapt to a highly dynamic computing environmentWith this it is the need to transfer the information quickly but efficiently and with complete security.IPSec is a method of providing privacy, integrity, and authenticity to information transferred across IP networks. IPSec gives the power to enable confidentiality, integrity, and authenticity in network infrastructure.
