Mobile Ad hoc Networking (MANET) MANET OLSRv2 Security Integrity protection ICV This document specifies integrity and replay protection for required implementation in the MANET Neighborhood Discovery Protocol (NHDP) and the Optimized Link State Routing Protocol version 2 (OLSRv2). This document specifies how an integrity check value (ICV) and a timestamp may be included as TLVs (defined in ) in NHDP's and OLSRv2's control messages, countering a number of security threats to NHDP and to OLSRv2. The ICV TLV uses a SHA-256 based HMAC and a single shared secret key. The timestamp TLV is based on POSIX time, assuming router synchronization. The mechanism in this specification can also be used for other MANET protocols using RFC5444.
