    abstract =  {This document analysis the use of hashes in SeND, possible threats and the impact of recent attacks on hash functions used by SeND. Current SeND specification {[}rfc3971{]} uses SHA-1 {[}sha-1{]} hash algorithm and PKIX certificates {[}rfc3280{]} and does not provide support for the hash algorithm agility. Based on previous analysis, this document suggests multiple hash support that should be included in the SeND update specification.},
