ISO/IEC 19592-2 on sharing secrets has just been released. It is the companion document to the ISO/IEC 19592-1. OK… This secret sharing scheme is a cryptographic technique. It breaks up a message into parts along with a message sharing algorithm for dividing the message and another for putting it back together again. The new ISO/IEC 19592-2 gives you the mechanisms to do this. Both are available from Document Center Inc. now.
I blogged about the ISO/IEC 19592-1 when it was released last year. The new Part 2 is titled Information technology – Security techniques – Secret sharing – Part 2: Fundamental mechanisms. It specifies how you’ll go about setting up the actual sharing scheme. It will contain two functions — message confidentiality and message recovery.
The standard begins with the usual scope, referenced documents and definition sections. There is an additional Clause 4 with symbols and abbreviated terms. Then we move directly into secret sharing schemes themselves in Clause 5. A number of schemes are reviewed. These include Shamir and Ramp Shamir. Additive, replicated additive, and computational additive are also included. Two informative Annexes cover object identifiers and numerical examples. An 8-item bibliography completes this 30 page document.
