[Cryptech Tech] Tech Digest, Vol 70, Issue 1

[Todd Arnold]

I've been a part of the IBM team that designs those HSMs since long before 
the 4758 - in fact, I was part of the original ad-tech group that did the 
research leading to our first HSM with that kind of packaging, the 4755 
which was announced in 1989.  While there are definitely a lot of 
similarities over generations, there has been an evolution and the current 
IBM HSMs are quite different from the 4758.  The technology used in the 
IBM 4769 HSM is covered to some degree in the paper "The IBM 4769 
Cryptographic
Coprocessor" In the September/November 2020 issue of the IBM Journal of 
Research and Development..  (https://ieeexplore.ieee.org/document/9138701) 
 I'd be happy to forward the PDF file to anyone who is unable to get to 
the web site.

Aloha!

(Sharing some HW pr0n this Friday.)

Was pointed to a very interesting paper that describes how IBM
manufactures FIPS Level 4, PCIe based HSMs. Quite a lot of resin and
glue required.

The paper nicely complements an older set of images that shows somebody
disassembling an older version of the IBM HSMs:

Interesting that this paper seems to completely erase from history the IBM
4758, which was more or less the same thing done twenty years earlier.  I
wonder what the politics behind that was?

Peter.
