The Secure Neighbor Discovery (SEND) Hash Threat Analysis

This document analyzes the use of hashes in Secure Neighbor Discovery(SEND), the possible threats to these hashes and the impact of recentattacks on hash functions used by SEND. The SEND specification[RFC3971] currently uses the SHA-1 [SHA1] hash algorithm and PKIXcertificates [RFC5280] and does not provide support for hash algorithmagility. This document provides an analysis of possible threats to thehash algorithms used in SEND.
