The authors present efficient constructions of Deterministic Encryption (DE) satisfying the new notion - security against privacy adversary (PRIV security), in the random oracle model. Their paper includes: a generic construction of deterministic length-preserving hybrid encryption, which is an improvement over the paper by researcher in crypto'07; to their best knowledge, this is the first example of length-preserving Deterministic Hybrid Encryption (DHE); post-quantum deterministic encryption, using the code-based encryption, which enjoys a simplified construction since its public key is re-used as a hash function; deterministic encryption with high message rate from witness-recovering encryption.
