"This is how the CryptDB paper says it should be used." First, there is no such statement in the CryptDB paper---at least we could not find one.
WebNov 27, 2012 · CryptDB’s approach is to execute SQL queries over encrypted data. It can do so practically with two techniques: using a collection of efficient SQL-aware encryption schemes, two of which are new, and onions of encryptions which allow dynamic adjustment of encryption schemes.
