| 英文摘要 | This paper proposes a blockcipher mode of operation, hctr, which is a length-preserving encryption mode. hctr turns an n-bit blockcipher into a tweakable blockcipher that supports arbitrary variable input length which is no less than n bits. the tweak length of hctr is fixed and can be zero. we prove that hctr is a strong tweakable pseudorandom permutation (sprp), when the underlying blockcipher is a strong pseudorandom permutation (sprp). hctr is shown to be a very efficient mode of operation when some pre-computations are taken into consideration. arbitrary variable input length brings much flexibility in various application environments. hctr can be used in disk sector encryption, and other length-preserving encryptions, especially for the message that is not multiple of n bits. |
