Abstract. We propose secret-key cryptosystems MISTY1 and MISTY2,
which are block ciphers with a 128-bit key, a 64-bit block and a
variable number of rounds. MISTY is a generic name for MISTY1 and
MISTY2. They are designed on the basis of the theory of provable
security against differential and linear cryptanalysis, and moreover
they realize high speed encryption on hardware platforms as well as
on software environments. Our software implementation shows that
MISTY1 with eight rounds can encrypt a data stream in CBC mode at a
speed of 20Mbps and 40Mbps on Pentium/100MHz and PA-7200/120MHz,
respectively. For its hardware performance, we have produced a
prototype LSI by a process of 0.5mu CMOS gate-array and confirmed a
speed of 450Mbps. In this paper, we describe the detailed
specifications and design principles of MISTY1 and MISTY2.

However, the IETF draft might be a supplement to the paper
above, which states in its final paragraph:
7 Conclusions
This paper proposed new secret-key block cryptosystems MISTY1 and
MISTY2. At present, the author recommends to use MISTY1 with eight
rounds, and to use MISTY2, which has a newer structure, with twelve
rounds. The next four pages show a complete and self-contained
description of MISTY1 and MISTY2.
But there are no "next four pages." Is the ITEF darft the missing part?
