摘要：
Conventional block ciphers that traffic in 128-bit block sizes are ill-suited for operating in small domains like credit card numbers. Some embodiments relate to techniques for constructing and speeding up practical and provably secure schemes for deterministically enciphering data from a small domain like credit card numbers using a conventional block cipher or other pseudorandom function.
