  1. Smart Access: Strong Authentication on the Web Ton.Verschuren@SURFnet.NL TNC Dresden 5-8 October 1998

  2. What’s the problem?

  3. Authentication solutions

  4. ROM EEPROM I/O etc R A M CPU Introducing…the smartcard • IBM MFC smartcard: • 8 bit Processor • 2K ROM (OS) • 10K EEPROM (Apps) • <1K RAM • 3,64Mhz clockspeed

  5. MF DF DF DF DF EF EF EF EF EF EF EF EF EF EF Smartcard intro (Cont’d) • MF Master File • DF Dedicated File • EF Elementary Files

  6. Access conditions For each command on a file: • ALW (Always) • CHV (CardHolder Verification) • PRO (Protected with key X) • Secure handshake with MAC • AUT (External Authentication) • ENC (Enciphered) • PRO plus encrypted data • NEV (never) (triple) DES !

  7. Student Smartcard • College pass • library pass • loan/grant registration number • membership data • e-purse (Chipper)

  8. Our model is ISI

  9. ISI Protocol

  10. Current applications • Downloading of commercial software(Smart Server) • Access to exam results database • Student grants/loans system • StudyNet: • registration for courses and exams • access to exam results

  11. Issues • Java implementations in browsers • Support for smartcard readers (com port) • Use of DES in public key world • Scaling of DES-based two-party authentication

  12. Tree-party Authentication

  13. Demo time! • Setup Card Reader • StudyNetFaculty of Arts, Utrecht University
