Speech Title: High Security Intelligent FH Sequence for Cognitive Frequency Hopping
Speech abstract:
Nowadays, various jamming, eavesdropping and other attacks become serious threats for the people’s information privacy in business and military applications. Hence, the information transmission of high security applications requires strong anti-jamming and anti-interception capability. Recently, a new technique named cognitive frequency hopping (FH) is proposed to realize the high security, reliability and efficient communication. As one of the key technologies for the FH commutation, the performance of the FH sequence, which controls the frequency regularity of the FH signal, determines the anti-intercept performance of the cognitive FH in practices. Meanwhile, the complexity, which means the ability to avoid the sequence being reconstructed from the obtained sub-sequence available, is the most important indicator to reflect the sequence’s security. This talk will introduce some of our works on study intelligent anti-jamming FH sequence based on the requirement of the high security cognitive FH communication, and the two complexity metrics based on the information entropy are proposed to evaluate the anti-cryptanalysis ability of the FH sequence. Accordingly, this intelligent anti-jamming FH sequence could be extensively applied in cognitive FHMA network, especially for the high security applications such as counter-terrorism, mobile communication, etc.
