Abstract
The 802.11 standard defines the Wired Equivalent Privacy (WEP) prhttps://www.inderscience.com/admin/articles/index.php?action=editEntry&subAction=nextArticleotocol and encapsulation of data frames for the purpose of security in WLAN systems. WEP suffers security pitfalls due to weak key management and Initialization Vector (IV) repetitions. To overcome these problems, in this work, the existing WEP protocol is modified to enhance the security of WLAN systems by dynamically changing the WEP key based on the network traffic intensity and frequent updating based on the number of frames transmitted. Security is further strengthened by implementing IV collision avoidance algorithm, also known as IV repetition avoidance algorithm, which ensures message privacy as the encryption is not breached.
