    IDV: Internet Domain Name Verification Based on Blockchain

    Ning Hu1, Yu Teng2, Yan Zhao1, Shi Yin1, Yue Zhao3,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.129, No.1, pp. 299-322, 2021, DOI:10.32604/cmes.2021.016839

    Abstract The rapid development of blockchain technology has provided new ideas for network security research. Blockchain-based network security enhancement solutions are attracting widespread attention. This paper proposes an Internet domain name verification method based on blockchain. The authenticity of DNS (Domain Name System) resolution results is crucial for ensuring the accessibility of Internet services. Due to the lack of adequate security mechanisms, it has always been a challenge to verify the authenticity of Internet domain name resolution results. Although the solution represented by DNSSEC (Domain Name System Security Extensions) can theoretically solve the domain name verification problem, it has not been… More >

    Blockzone: A Decentralized and Trustworthy Data Plane for DNS

    Ning Hu1, Shi Yin1, Shen Su1, *, Xudong Jia1, Qiao Xiang2, Hao Liu3

    CMC-Computers, Materials & Continua, Vol.65, No.2, pp. 1531-1557, 2020, DOI:10.32604/cmc.2020.010949

    Abstract The domain name system (DNS) provides a mapping service between memorable names and numerical internet protocol addresses, and it is a critical infrastructure of the Internet. The authenticity of DNS resolution results is crucial for ensuring the accessibility of Internet services. Hundreds of supplementary specifications of protocols have been proposed to compensate for the security flaws of DNS. However, DNS security incidents still occur frequently. Although DNS is a distributed system, for a specified domain name, only authorized authoritative servers can resolve it. Other servers must obtain the resolution result through a recursive or iterative resolving procedure, which renders DNS… More >
