    abstract =  {Many of the post quantum cryptographic algorithms have either large public keys or signatures. In the interest of reducing bandwidth of transitting X.509 certificates, this document defines new public key and signature algorithms for referencing external public key and signature data by hash, URL, etc. This mechanism is designed to mimic the behaviour of an Authority Information Access extension.},
