It is, maybe, worthwhile to compare the section ``Shortcut for RSA decryption''
(attributed to Charles Merritt, 1984, 1985) of this paper (there is also
errata in another issue of IEEE Computer) and the paragraph
``Fast deciphering algorithm'' of the following paper:

J.-J. Quisquater and C. Couvreur, ``Fast decipherment algorithm for RSA
public-key cryptosystem'', Electronics Letters, 14th Oct. 1982, Vol.18, 
No. 21, pp. 905-907.

Any way ISO (International Standard Organisation) is studying the use
of public-key systems for signature (only) under the working group
TC97/SC20/WG2. I know that because I am the editor of the (draft) 
document (accepted and presented with Louis Guillou -- CCETT, Rennes, France --
at CRYPTO'87, Santa Barbara, Calif., 16-20 Aug.).
