Two Security Building Blocks: SNEP (Secure Network Encryption Protocol): –Provide data confidentiality, two-party data authentication, evidence of data freshness.  TESLA (micro version of TELSA) TELSA: Timed Efficient Stream Loss-Tolerant Authentication Protocol –Authenticated broadcast for resource constrained environment. –Source authentication; data not modified en route. –Use symmetric crypto function (Message Authentication Code MAC function) By Adrian Perrig et al at UC Berkeley.
