چکیده
Recently proposed algebraic attack has been shown to be very effective on several stream ciphers. In this paper, we have investigated the resistance of PingPong family of stream ciphers against algebraic attacks. This stream cipher was proposed in 2008 to enhance the security of the improved summation generator. In particular, we focus on the PingPong-128 stream cipher’s resistance against algebraic attack in this paper. In our analysis, it is found that an algebraic attack on PingPong family of stream ciphers require much more operations compare to the exhaustive key search on the internal state of the LFSRs. It will be shown that due to the irregular and mutual clock controlling in PingPong stream cipher the degree of the generated equation tends to grow up with each successive clock which in turn increases the overall complexity of an algebraic attack. Along with the PingPong-128 stream cipher the other instances of PingPong family stream ciphers are also investigated against the algebraic attack. Our analysis shows that, PingPong family stream ciphers are highly resistant against the algebraic attack due to their mutual and irregular clocking function.

متن کاملA Routing Protocol based on Temporal-awareness Ordered-MPR for Dynamic Wireless Multi-hop Mobile Networks
Dynamic mobile Wireless Network is one important infrastructure for special environment or special applications. High delay and low delivery ratio are its major challenges because of the absence of a complete end-to-end path between source nodes to destination nodes. Although some protocols have been proposed, they usually ignore the action diversity, communication time and duration. In this pa...

متن کاملAn Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
متن کاملComparative Performance Analysis of AODV,DSR, TORA and OLSR Routing Protocols in MANET Using OPNET
Mobile Ad Hoc Networks (MANETs) are receiving a significant interest and are becoming very popular in the world of wireless networks and telecommunication. MANETs consist of mobile nodes which can communicate with each other without any infrastructure or centralized administration. In MANETs, the movement of nodes is unpredictable and complex; thus making the routing of the packets challenging....
