Abstract: Wireless is the next generation networking technology. The security of such technology is very critical because its physical layer is the electro-magnetic waves that can be easily intercepted by anyone. The original security protocol for 802.11 wireless networks is called WEP (Wired Equivalent Privacy). It is a protocol that is based on symmetric-key encryption algorithm RC4 (Rivest Cipher 4). Unfortunately, this protocol had many flaws that made it exposed to many attacks. This paper presents a set of improvements for WEP, which include key management and distribution, and authentication. These improvements convert WEP to a hybrid cryptosystem, a system that is based on both a symmetric-key algorithm and an asymmetric-key algorithm.
