-    A zone in GNS is defined by a public/private ECC key pair (x,zk),

-    zk := x*P the corresponding public key.
+    A zone in GNS is defined by a public/private ECC key pair (d,zk),
+    where B is the generator of a group or subgroup, d is the private key and
+    zk the corresponding public key.
     The keys are constructed using the Ed25519 ECC scheme as defined in
     <xref target="RFC8032" />.
     The public key "zk" is used to uniquely identify and refer to the zone and
     is thus called "zone key".
     Records published in the zone are signed using a private key derived
-    from the private key "x" as described in <xref target="publish" />.
+    from "d" as described in <xref target="publish" />.
