    abstract =     {As sensor networks edge closer towards wide-spread deployment, security issues
    become a central concern. So far, much research has focused on making sensor
    networks feasible and useful, and has not concentrated on security.

    We present a suite of security building blocks optimized for
    resource-constrained environments and wireless communication. SPINS has two
    secure building blocks: SNEP and mTESLA. SNEP provides the following
    important baseline security primitives: Data confidentiality, two-party data
    authentication, and data freshness. A particularly hard problem is to provide
    efficient broadcast authentication, which is an important mechanism for sensor
    networks. mTESLA is a new protocol which provides authenticated broadcast for
    severely resource-constrained environments.  We implemented the above
    protocols, and show that they are practical even on minimal hardware: the
    performance of the protocol suite easily matches the data rate of our network.
    Additionally, we demonstrate that the suite can be used for building higher
    level protocols.}
