LDPC Codes for the Gaussian Wiretap Channel

Abstract

Physical Layer Security in Wireless Communications the gains that multiple antennas provide. Additional and more complete treatments of the physical layer security problem can be found in [1][2][3][4] as well as other chapters in this book.

The Design of WLAN Wireless Access Protocol based on Certified NFC

“…At this point, Alice also obtained the same K as Bob's,K is the same the actual value as the K in formula (5).…”

“…The process of WLAN authentication mainly include WEP, WPA/connected wpa2-psk, WPS three [1][2][3].However, the weakness of this encryption algorithm is to collect enough IV when RC4 stream of bytes and the first byte, key can be acquired [4]. WPA / wpa2-psk authentication method is widely used, and relatively safe, however, if the users can collect in the certification of 4-way handshake packet when using methods such as dictionary attacks can crack the PSK during the waiting time [5]. On the basis of WPA / WPA2-PSK, the WPS authentication mode is put forward [6].However, this authentication system can not be obtained or rule to judge the legitimacy of PSK users.…”
