USENIX Technical Program - Abstract - Smartcard 99
Software License Management with Smart Cards
Tuomas Aura, Helsinki University of Technology; Dieter Gollmann, Microsoft Research
Abstract
This paper describes public-key protocols for binding software
licenses to tamper-resistant smart cards, for transferring licenses
between cards, and for purchasing them on-line. The protocols support
software distribution both through retail stores and over the
Internet. The user can transfer licenses from several cards onto a
single card to avoid juggling between several cards in the reader. The
protocols are based on signed delegation certificates that are mostly
stored outside the smart card. A smart card reader and cards capable
of public-key signatures are the only new hardware needed. The
protocols are easy for the user and simple to implement and analyze.
We prove the security of the transfer protocol.
