This memo describes a mechanism to provide a secure binding between
the multiple addresses with different prefixes available to a host
within a multihomed site.  This mechanism employs either
Cryptographically Generated Addresses (CGAs) or a new variant of the
same theme that uses the same format in the addresses.  The main idea
in the new variant is that information about the multiple prefixes is
included within the addresses themselves.  This is achieved by
generating the interface identifiers of the addresses of a host as
hashes of the available prefixes and a random number.  Then, the
multiple addresses are generated by prepending the different prefixes
to the generated interface identifiers.  The result is a set of
addresses, called Hash-Based Addresses (HBAs), that are inherently
bound to each other.  [STANDARDS TRACK]
