  • Public-Key quantum digital signature scheme with one-time pad Private-Key
    Quantum Information Processing, 2017
    Co-Authors: Feng-lin Chen, Su-gen Chen, Zhi Hua Wang
    Abstract:

    A quantum digital signature scheme is firstly proposed based on public-Key quantum cryptosystem. In the scheme, the verification public-Key is derived from the signer’s identity information (such as e-mail) on the foundation of identity-based encryption, and the signature Private-Key is generated by one-time pad (OTP) protocol. The public-Key and Private-Key Pair belongs to classical bits, but the signature cipher belongs to quantum qubits. After the signer announces the public-Key and generates the final quantum signature, each verifier can verify publicly whether the signature is valid or not with the public-Key and quantum digital digest. Analysis results show that the proposed scheme satisfies non-repudiation and unforgeability. Information-theoretic security of the scheme is ensured by quantum indistinguishability mechanics and OTP protocol. Based on the public-Key cryptosystem, the proposed scheme is easier to be realized compared with other quantum signature schemes under current technical conditions.

  • distributed machine learning oriented data integrity verification scheme in cloud computing environment
    IEEE Access, 2020
    Co-Authors: Xiaoping Zhao, Rui Jiang
    Abstract:

    Distributed Machine Learning (DML) is one of the core technologies for Artificial Intelligence (AI). However, in the existing distributed machine learning framework, the data integrity is not taken into account. If network attackers forge the data, modify the data, or destroy the data, the training model in the distributed machine learning system will be greatly affected, and the training results are led to be wrong. Therefore, it is crucial to guarantee the data integrity in the DML. In this paper, we propose a distributed machine learning oriented data integrity verification scheme (DML-DIV) to ensure the integrity of training data. Firstly, we adopt the idea of Provable Data Possession (PDP) sampling auditing algorithm to achieve data integrity verification so that our DML-DIV scheme can resist forgery attacks and tampering attacks. Secondly, we generate a random number, namely blinding factor, and apply the discrete logarithm problem (DLP) to construct proof and ensure privacy protection in the TPA verification process. Thirdly, we employ identity-based cryptography and two-step Key generation technology to generate data owner’s public/Private Key Pair so that our DML-DIV scheme can solve the Key escrow problem and reduce the cost of managing the certificates. Finally, formal theoretical analysis and experimental results show the security and efficiency of our DML-DIV scheme.

  • Authentication in wireless mesh networks
    'Informa UK Limited', 2014
    Co-Authors: Boudguiga Aymen, Laurent Maryline
    Abstract:

    International audienceDeployment of Wireless Mesh Networks (WMNs) is growing as they serve advantageously to enlarge wired backbones, especially in country side areas where the cost of introducing a wired network to few costumers is very expensive. WMNs can also be used as home networks to interconnect all the home devices together with no constraints for the traffic to go through a hub. WMNs are constructed as community networks. That is, a community peer to peer network is built within the WMN, and it fully supports local traffic transferring between stations of the community thanks to some multi-hop routing protocols. As mesh networks are spreading quickly, providing a reliable authentication service is becoming compulsory. Most of the current authentication solutions rely on the 802.1X standard and the Extensible Authentication Protocol (EAP) or on ID-based cryptography. They refer either to a public/Private Key Pair or to a secret shared between the two authenticating stations. We propose to review, in this chapter, the most known authentication protocols that have been proposed for the authentication of wireless mesh network stations either in IEEE standards or in research literatur
