Detection of cache pollution attacks using randomness checks
2012 IEEE International Conference on Communications (ICC), 2012The Internet plays an increasing role in content dissemination as user-generated contents have exploded recently. Cache servers have been deployed to bypass bottlenecks in the network so that contents can be delivered to end users more efficiently. With caches becoming more embedded in the networks, emerging threats follow naturally.

Gini impurity based NDN cache pollution attack defence mechanism
Journal of Information and Optimization Sciences, 2020Name Data Network (NDN) is a futuristic Internet architecture that delivers content based on strategically chosen names and caches content on intermediate routers in the content-delivery path, whic...

Intelligent Pollution Controlling Mechanism for Peer to Peer Caches
2015 Seventh International Conference on Computational Intelligence, Modelling and Simulation (CIMSim), 2015This paper addresses the problem of cache pollution in P2P (Peer-to-peer) systems. P2P traffic has a significant impact on ISPs as it accounts for more than half of the all traffic. This will cause some negative impact on the Internet like network congestion, high latency. P2P caching is an efficient method for handling this problem.

Is your caching resolver polluting the internet?
Proceedings of the ACM SIGCOMM workshop on Network troubleshooting research, theory and operations practice meet malfunctioning reality - NetT '04, 2004Previous research has shown that most of the DNS queries reaching the root of the hierarchy are bogus [1]. This behavior derives from two constraints on the system: (1) queries that cannot be satisfied locally percolate up to the root of the DNS; (2) some caching nameservers are behind packet filters or firewalls that allow outgoing queries but block ...

CoMon++: Preventing Cache Pollution in NDN Efficiently and Effectively
2017 IEEE 42nd Conference on Local Computer Networks (LCN), 2017Defending against cache pollution attacks, highly detrimental attacks that are easy to implement in Named-Data Networking (NDN), currently suffers from the lack of coordination. Solving cache pollution attacks is a prerequisite for the deployment of NDN, which is widely considered to be the basis for the future Internet. We present CoMon++ to this end,

Reducing Cache Pollution of Threaded Prefetching by Controlling Prefetch Distance
2012 IEEE 26th International Parallel and Distributed Processing Symposium Workshops & PhD Forum, 2012Threaded prefetching based on Chip Multiprocessor (CMP) issues memory requests for data needed later by the main computation, and therefore may lead to increased stress on limited shared cache space and bus bandwidth. In our earlier work, we had proposed an effective threaded prefetching technique that selects proper prefetch distance for specific ...

Mitigating the cache data pollution by using branch path tracking
Proceedings of 2012 2nd International Conference on Computer Science and Network Technology, 2012“Memory Wall” is one of the most important problems which must be solved for designing high performance processors. Efficient and intelligent cache system is key component of processor's memory system. We notice that cache pollution caused by the speculative execution of memory accessing instructions in predictive path may affect the cache and ...

A hardware-based cache pollution filtering mechanism for aggressive prefetches
2003 International Conference on Parallel Processing, 2003. Proceedings., 2003Aggressive hardware-based and software-based prefetch algorithms for hiding memory access latencies were proposed to bridge the gap of the expanding speed disparity between processors and memory subsystems. As smaller L1 caches prevail in deep submicron processor designs in order to maintain short cache access cycles, cache pollution caused by ...

The performance of pollution control victim cache for embedded systems
Proceedings of the 21st annual symposium on Integrated circuits and system design, 2008In this paper we explore the design space of data caches looking for the combinations of design parameters that produce the best results at the smallest sizes. We introduce a technique named Pollution Control Victim Cache (PCVC) which improves the Pollution Control Cache (PCC), is simpler and performs better.

W-Order Scan: Minimizing Cache Pollution by Application Software Level Cache Management for MMDB
2011The utilization of shared LLC(Last Level Cache) is important for efficiency of multi-core processor. Uncontrolled sharing leads to cache pollution i.e. the weak locality data(single-usage data without re-using) continuously evict the strong locality data (frequently re-used data) from LLC in both inner query processing and co-running programs.
