  1. EndeavourSecurity and assurance Doug Tygar tygar@cs.berkeley.edu UC Berkeley 25 May 1999

  2. Challenges:Protocols and Mobile Applications • Two sides for mobile applications: • protecting the remote host from the mobile code • protecting the mobile code from the remote host! • Automatic generation of best security protocol • Ad hoc and temporal access control • Access control/security negotiation • Use of cryptographic hardware tokens • How to evaluate, build, break tamper-resistant boundaries • Differential power analysis

  3. Wider challenges • Microauctions/economics for resource control • Rights management tagging • Design for survivability • All of this with privacy

  4. Plan • One year • Synthesis of code for optimal security protocols • Toolkit for cryptographic key management for mobile code • Design of ad hoc and temporal access control • “Little TEMPEST” protection for hardware tokens • Three year • Integration with applications across Endeavour • Privacy analysis for high assurance mechanisms • Automatic or semi-automatic resource allocation using micro-auctions. • High survivability mechanisms

  5. Latest wrinkle -- power analysis attacks • Publicized by Paul Kocher et al. • Use current drawn by device to read off cryptographic key • Typical MOS Transistor:

  6. Simple Power Analysis

  7. Differential Power Analysis
