Yes, this is fine, at the record level. (What you've built would be classified as a "Encrypt-then-Authenticate" scheme in the literature, and there are standard provable security results for such schemes.) Well done on constructing a solid, well-engineered cryptographic scheme. An AEAD mode would spare you from having to invent such a scheme, but what ...

CipherCloud's website now clearly states, here, that CipherCloud DOES NOT use homomorphic encryption. This also states that CipherCloud DOES NOT implement 1:1 mapping or ECB mode in any customer deployment. Other statements are next to acknowledging that CipherCloud's early demos did that, citing the will to illustrate the functionality, features that where ...

That paper refers to the numerical ordering, while what would be relevant for searchable encryption without changes to the providers is the substring ordering. $\:$ (Thus, their bound does not apply.) What do you mean by "existing queries in a database"? If your assumption holds, then { Encryption must be deterministic (given the key), since different ...
