Persistence Landscapes—Implementing a Dataset Verification Method in Resource-S...
Branco, Sérgio; Dogruluk, Ertugrul; Carvalho, João G.; Reis, Marco S.; Cabral, JorgeAs more and more devices are being deployed across networks to gather data and use them to perform intelligent tasks, it is vital to have a tool to perform real-time data analysis. Data are the backbone of Machine Learning models, the core of intelligent systems. Therefore, verifying whether the data being gathered are similar to those used for model building is essential. One fantastic tool for the performance...

A countermeasure approach for brute-force timing attacks on cache privacy in na...
Dogruluk, Ertugrul; Macedo, Joaquim; Costa, AntónioOne key feature of named data networks (NDN) is supporting in-network caching to increase the content distribution for today’s Internet needs. However, previously cached contents may be threatened by side-channel timing measurements/attacks. For example, one adversary can identify previously cached contents by distinguishing between uncached and cached contents from the in-network caching node, namely the edge ...
Public key certificate privacy in VoNDN: voice over named data networks
Dogruluk, Ertugrul; Gama, Óscar Sílvio Marques Almeida; Costa, António; Macedo, JoaquimNamed Data Network (NDN) is a network paradigm that attempts to answer today's needs for distribution. One of the NDN key features is in-network caching to increase content distribution and network efficiency. However, this feature may increase the privacy concerns, as the adversary may identify the call history, and the callee/caller location through side-channel timing responses from the cache of trusted Voic...
Side-channel timing attack on content privacy of named data networking
Dogruluk, ErtugrulA diversity of current applications, such as Netflix, YouTube, and social media, have used the Internet mainly as a content distribution network. Named Data Networking (NDN) is a network paradigm that attempts to answer today’s applications need by naming the content. NDN promises an optimized content distribution through a named content-centric design. One of the NDN key features is the use of in-network cachi...
A detection and defense approach for content privacy in named data network
Dogruluk, Ertugrul; Costa, António; Macedo, JoaquimThe Named Data Network (NDN) is a promising network paradigm for content distribution based on caching. However, it may put consumer privacy at risk, as the adversary may identify the content, the name and the signature (namely a certificate) through side-channel timing responses from the cache of the routers. The adversary may identify the content name and the consumer node by distinguishing between cached and...
Identifying previously requested content by side-channel timing attack in NDN
Dogruluk, Ertugrul; Costa, António; Macedo, JoaquimNDN is a new name-based network paradigm. It is designed to keep the contents in the cache to increase the network efficiency. However, previously requested content may put the user privacy at risk. The time difference between cached and non-cached contents of interest responses can be used by an adversary to determine previously requested contents in cache. This attack is classified as side-channel timing atta...
Evaluating privacy attacks in named data network
Dogruluk, Ertugrul; Costa, António; Macedo, JoaquimThe main usage pattern of the Internet is changing from end-to-end communication to content distribution and access. To support this change, the actual Internet has several add-on as Content Delivery Networks (CDNs) and Web caches.To have a native support architecture for content distribution, clean state information-centric networking is being proposed for Future Internet. The Named Data Network (NDN) is one o...
