| Since proximity is the only requirement to intercept the signals of a wireless local area network (LAN), wireless networks are inherently insecure. Therefore, solutions that provide wireless access to a network that is constantly changing in an indeterminate fashion with the added benefit of customizable encryption to allow for the advances in technology are of significant interest to numerous markets.; This thesis involves the design and implementation of an application-level system designed for a wireless networking environment while employing well-accepted, variable cryptographic techniques. The approach to deliver such services consists of using features of the latest Java Platform—Java Platform 2 Standard Edition (ME). In addition to the common features of network communication, multi-threading, and streaming, J2SE 1,4 also provides powerful cryptography algorithms in the Java Cryptography Extension (JCE).; As a result, the system has been developed into an application programming interface (API) that is deployable to all common architectures, inherently extendable, and highly configurable by design. The system, in suggested form, relies on a respected assymetrical key encryption scheme, Diffie-Hellman, and a block cipher encryption scheme, Blowfish, that can allows for significantly large key lengths. Thus, the system is a substantial solution to meet the needs for application level security in a wireless networking environment,... |
