  <p>I am looking for a block cipher that supports small block sizes,  ideally 16bits in size.  I want to use CMAC mode,  so using a block cipher with OFB mode or a stream cipher is undesirable.  Speed is very important,  and the cipher shouldn't be susceptible to known attacks.  This is a theoretical application and high security isn't required,  however speed is very important.  </p>
  
  <p>Does something like this exist?  How close to these specs can I get?</p>
