Study Data from Michigan State University Update Knowledge of Data Encryption

May 20, 2014

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- New research on Data Encryption is the subject of a report. According to news reporting from East Lansing, Michigan, by VerticalNews journalists, research stated, "This paper considers primary user emulation attacks in cognitive radio networks operating in the white spaces of the digital TV (DTV) band. We propose a reliable AES-assisted DTV scheme, in which an AES-encrypted reference signal is generated at the TV transmitter and used as the sync bits of the DTV data frames."

The news correspondents obtained a quote from the research from Michigan State University, "By allowing a shared secret between the transmitter and the receiver, the reference signal can be regenerated at the receiver and used to achieve accurate identification of the authorized primary users. In addition, when combined with the analysis on the autocorrelation of the received signal, the presence of the malicious user can be detected accurately whether or not the primary user is present. We analyze the effectiveness of the proposed approach through both theoretical analysis and simulation examples. It is shown that with the AES-assisted DTV scheme, the primary user, as well as malicious user, can be detected with high accuracy under primary user emulation attacks. It should be emphasized that the proposed scheme requires no changes in hardware or system structure except for a plug-in AES chip."

According to the news reporters, the research concluded: "Potentially, it can be applied directly to today's DTV system under primary user emulation attacks for more efficient spectrum sharing."
