Hello,

this new draft describes a threshold secret sharing method. I suggest  
that this draft be the basis for an RFC (informational would be fine,  
I expect), and I welcome comments on it.

best regards,

David

> Creation_date:	 2008-12-19
> WG ID:		 Independent Submission
> Number_of_pages: 24
>
> Abstract:
> Threshold secret sharing (TSS) provides a way to generate N shares
> from a value, so that any M of those shares can be used to
> reconstruct the original value, but any M-1 shares provide no
> information about that value.  This method can provide shared access
> control on key material and other secrets that must be strongly
> protected.
>
> This note defines a threshold secret sharing method based on
> polynomial interpolation in GF(256) and a format for the storage and
> transmission of shares.  It also provides usage guidance, describes
> how to test an implementation, and supplies test cases.
