Caching Encrypted Content Via Stochastic Cache Partitioning

IEEE/ACM Transactions on Networking, 2018
In-network caching is an appealing solution to cope with the increasing bandwidth demand of video, audio, and data transfer over the Internet. Nonetheless, in order to protect consumer privacy and their own business, content providers (CPs) increasingly deliver encrypted content, thereby preventing Internet service providers (ISPs) from employing ...

Security of Cached Content in NDN

IEEE Transactions on Information Forensics and Security, 2017
In Named-Data Networking (NDN), content is cached in network nodes and served for future requests. This property of NDN allows attackers to inject poisoned content into the network and isolate users from valid content sources. Since a digital signature is embedded in every piece of content in NDN architecture, poisoned content is discarded if routers ...

Popularity-driven content caching

IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications, 2016
This paper presents a novel cache replacement method — Popularity-Driven Content Caching (PopCaching). PopCaching learns the popularity of content and uses it to determine which content it should store and which it should evict from the cache. Popularity is learned in an online fashion, requires no training phase and hence, it is more responsive to ...

Popularity-Based Content Cache Management for in-Network Caching

2019 International Conference on Information Networking (ICOIN), 2019
In-network caching is a technique that stores contents in caches of routers, and thus reduces the loads for content servers and networks. To further enhance the performance of in-network caching, this paper proposes a popularity-based content cache management method.

Optimal Caching with Content Broadcast in Cache-and-Forward Networks

2011 IEEE International Conference on Communications (ICC), 2011
With the rapid advance in the technology area of data storage, storage capacities have increased substantially while the price has been dropping fast. Motivated by this trend, it has been proposed in the Cache-and-Forward architecture that storage is incorporated into each intermediate CNF router.

Caching dynamic contents with varying popularity

2021 19th International Symposium on Modeling and Optimization in Mobile, Ad hoc, and Wireless Networks (WiOpt), 2021
We study content caching in a cellular network consisting of a base station with a cache. New contents arrive in the network according to a Poisson process and the contents stay for exponentially distributed times. At any given time, all the contents in the network have the same popularity or request rate. Also, contents’ request rates are time-varying,

Refreshment policies for Web content caches

Proceedings IEEE INFOCOM 2001. Conference on Computer Communications. Twentieth Annual Joint Conference of the IEEE Computer and Communications Society (Cat. No.01CH37213), 2002
Web content caches are often placed between end-users and origin servers as a mean to reduce server load, network usage, and ultimately, user-perceived latency. Cached objects typically have associated expiration times, after which they are considered stale and must be validated with a remote server (origin or another cache) before they can be sent to ...

Content discovery and caching in mobile networks

21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010
We consider content discovery in wireless networks with infrastructure, where mobile nodes store, advertise and consume contents while Broker entities running on infrastructure devices let demand and offer meet. We refer to this paradigm as match-making, highlighting its features within the confines of the standard publish-and-subscribe paradigm.

Distributed cache management considering content popularity for in-network caching

2017 23rd Asia-Pacific Conference on Communications (APCC), 2017
This paper proposes a new cache management method considering the popularity of contents for in-network caching. In networks with in-network caching, routers store contents in their cache and users can download them from the routers. By utilizing cached contents, the loads for content servers and networks can be reduced.

Dynamic cache rental and content caching in elastic wireless CDNs

2018 16th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt), 2018
With elastic CDNs, content providers can rent cache space on demand at different cloud locations in order to enhance their offered quality of service (QoS). This paper addresses a key challenge in this context, namely how to invest an available budget in cache space in order to match spatio-temporal fluctuations of file demand and storage price ...
