We present a family of hyperelliptic curves whose Jacobians are suitable for cryptographic use, and whose parameters can be specified in a highly efficient way. ...
This is done via complex multiplication and identity-based parameters. We also present some novel computational shortcuts for these families. ...
Introduction In our earlier paper [1] we introduced the notion of elliptic curves with compact parameters. ...
