NIST vydal Interagency Report 7539, Symmetric Key Injection onto Smart Cards
19.12.2008Abstract:
There is
significant interest in conducting a fast, accurate, and highly
secured authentication transaction using symmetric keys in PACS
environments. This paper describes architectures for securely
injecting secret keys onto smart cards which are used in PACS
environment. Specifically, this paper suggests ways to load site
specific symmetric keys onto a PIV Card after the card has been
issued, which allows each smart card to share a unique secret key
with each PACS with which it interacts. The paper presents four
protocols that enable a Card Management System (CMS) to securely load
site specific PACS symmetric keys. Each protocol presents unique
security characteristics and uses the PIV Card's card management key
in different capacities.
