  1. An Efficient Software Protection Scheme Antonio Maña, Ernesto Pimentel University of Málaga, Spain Trusted Information: The New Decade Challenge, IFIP TC11 Sixteenth Annual Working Conference on Information Security, June 11-13, 2001, Paris, France. Presented by Matt Barrett, mbar116@ec.auckland.ac.nz

  2. Summary The paper describes a software based protection scheme using smart-card based hardware tokens allowing Internet based software distribution, with a powerful license management system.

  3. Appreciative Comment • Thorough description of problem • Well stated and defensible justification • “…it is concluded that to obtain a provable secure protection scheme we must have a tamperproof processor that contains and executes the protected software.”

  4. Critical Comment • Unclear definition of schemes • Fail to separate two descriptions • Error in diagrams • Marked difference in clarity • Explanations could be more concise

  5. Scheme One

  6. Scheme Two

  7. Appreciative Comment • Licensing management • Free distribution over the Internet • Easy recovery of lost licenses • Transfer of licenses to other smart cards • Expiration of license • Extremely useful features, giving scheme a wide scope of usefulness

  8. Discussion • Just not practical for use with software • “The cat is already out of the bag.” • Could the principles of this scheme be modified for use with pure content?
