What was the criteria used by the IEEE 802.11 committee to design WEP?
What will be an ideal response?
The IEEE 802.11 committee designed WEP to meet the following criteria:
* Efficient-The WEP algorithm must be proficient enough to be implemented in either hardware or software.
* Exportable-WEP must meet the guidelines set by the U.S. Department of Commerce so that the wireless device using WEP can be exported overseas.
* Optional-The implementation of WEP in wireless LANs is an optional feature.
* Reasonably strong-The security of the algorithm lies in the difficulty of determining the secret keys through attacks. This in turn is related to the length of the secret key and the frequency of changing keys. WEP was to be "reasonably" strong in resisting attacks.
* Self-synchronizing-When using WEP, each packet must be separately encrypted. This is to prevent a single lost packet from making subsequent packets indecipherable.
