  • How to protect the location privacy is an
    important security issue in wireless sensor network. Pre-
    vious works mainly focus on the routing-level location pri-
    vacy problems. This paper however introduces a data-level
    location privacy problem, i:e., the Privacy preserving hop-
    distance computation (PPHC) problem, and proposes a
    PPHC protocol to solve this problem. In this protocol, the
    data disguise techniques in the secure multi-party compu-
    tation ¯eld is successfully applied to protect the location
    privacy of each participant. The most advantage of this
    protocol is that it does not require any trusted third-party
    or encryption operations, and thus has a much better per-
    formance than the traditional solution generally based on
    a trusted third-party and encryption operations. The per-
    formance analysis shows that the computational overhead
    of this protocol is only O(1), and the communication over-
    head is dominated by two rounds of message delivery.
