Intermediate report about wireless secrecy metrics and preliminary algorithms : NEWCOM++ DR.A.1

• This deliverable provides a first overview of the state of the art on wireless security metrics and algorithms,which are particularly very important with respect to the intrinsic vulnerability of the wirelessmedium. The first part deals with building practical physical layer information-theoretic secure schemes.Indeed, Shannon formalized the concepts of capacity (as a transmission efficiency measure) and equivocation(as a measure of secrecy). While the concept of capacity has been extended to fading channelswith the introduction of concepts like the outage capacity or the ergodic capacity, similar paths are yet tobe developed concerning equivocation. In the second part, we present a taxonomy of threats for wirelessnetworks, and particularly for wireless sensor networks, in terms of the affected protocol layers. Besides,an overview to attack tree and attack graph techniques as formal means for describing and measuringvulnerabilities and thus also for assessing also the security level of wireless sensor networks is provided.Finally, an overview to suitable security concepts for wireless networks is given
