The keyspace congregates one or more column families in the application, similar to a schema in a relational database.
If the attacker responds with a set of valid colluding nodes, its attack results ineffective because the colluders' ids are scattered along the keyspace, so the lookup procedure proceeds properly.
The challengers were lucky; they found the key after searching only 24% of the keyspace.
