Secure Caching Scheme by Using Blockchain for Information-Centric Network-Based Wireless Sensor Networks

Abstract

This paper addresses a secure caching scheme for information-centric network (ICN)-based wireless sensor networks (WSNs). In order to achieve the above mechanism, we utilize both the public-key cryptography technique and the blockchain technique, which enable data to be safely gathered and the decentralized and crossverified sensing data to be copied and stored. In addition, we propose a protocol design for introducing the proposed structure into an ICN-based WSN system. Furthermore, we formulate statistical models and demonstrate numerical results by performing computer simulations and hardware-based experiments.

Secure Caching Scheme Using Blockchains for Unmanned Aerial Vehicle-Assisted Information-Centric Wireless Sensor Networks

“…In this section, we will demonstrate that the proposed scheme can overcome the remaining problems outlined in our previous study [7]. As far as we know, the PoW scheme (including Ethereum) is utilized as the consensus scheme for typical related systems.…”

“…To demonstrate the above advantage, we developed a hardware-based testbed device using the familiar single-board computer of a Raspberry Pi 3 with the default Raspbian kernel version 10. As in our previous study [7], for a hash function, we used the firstgeneration secured hash algorithm (SHA-1) method [29], which is widely utilized for general purposes. We implemented the prototype program code using C++ language with the CLX C++ library [30] and we compiled and linked an executable binary program by using the GNU GCC compiler.…”

“…From the above perspective, in our previous study [7], we proposed a secure caching scheme using blockchains for ICN-WSNs. In our previous study, however, we adopted a proof-of-work (PoW) scheme as a block verification (to commit a new block to append a blockchain among all member nodes).…”

Um Arcabouço para Validação de Conteúdo em Redes de Dados Nomeados baseado em Blockchain

“…Em [Mori 2018], propõe-se um esquema para assegurar a integridade e autenticidade da fonte de dados de sensoriamento na cache em redes de sensores sem fio baseadas em NDN. Nesse sentido, os autores adotaram duas tecnologias chave: criptografia assimétrica e blockchain.…”

“…Em NDNs, essa tecnologia tem sido adotada para garantir a integridade de conteúdos na cache em redes de sensores sem fio [Mori 2018], implementar uma rede blockchain propriamente dita sobre NDN, de forma a otimizar o desempenho de transações de criptomoedas e gerenciamento de chaves criptográficas [Jin et al 2017]. Todavia, em sua maioria, os trabalhos não abordam o esquema de permissionamento de provedores ou sequer consideraram a presença de produtores maliciosos na rede.…”
