We present several constructions of tweakable enciphering schemes which use a single encryption
layer between two layers of universal hash function computation. The earliest known construction
of this type is due to Naor and Reingold, where the encryption layer is the electronic codebook
mode. A more recent work of this type is TET and is due to Halevi at Crypto 2007.
