Reasoning about Security Issues in Wireless Devices based on the IEEE 802.11
Original language description
This papers deals with a security provided by the Wireless Networks based on the IEEE 802.11 standard. This standard specifies the Wired Equivalent Privacy (WEP) encapsulation of 802.11 data frames to provide confidentiality, access control, and data integrity. WEP appends a 32-bit CRC checksum to each outgoing frame, and then encrypts it with RC4 using 40- or 104-bit message-key plus a 24-bit random initialization vector. WEP also decrypts each incoming frame with the message-key, and validates the CRCC checksum. In this protocol, RC4 and the shared message-key are used for confidentiality and access control, and CRC checksum for data integrity. However, WEP has been shown to fail to meet its design goals. Use of RC4 for data privacy and CRC-32 for data integrity is due mainly to their speed and ease of implementation, but they do not provide cryptographically-secure encryption and authentication.<br>Many serious security flaws have been exposed in these two design choices. These secu
