  1. Ebola OR The Abolition of Root

  2. Ebola Equality Based Operating LAir (suggestions welcome)

  3. Traditional Security Architectture

  4. Ebola Architecture

  5. Kernel Requirements • Microkernel • Security • Flexibility • Scheduling • Reliability

  6. Subsystems • Cryptographic • Logging • I/O • Communication • Election/Authentication

  7. Cryptographic Subsystem • Symmetric • Assymetric • Threshold • Digital Signature

  8. Logging Subsystem • Local • Remote • Cached in file until full • Hashed, Encrypted, sent to random user • Receipt • Hash, UID recordedand encrypted

  9. Input/Ouput Subsystem • Mostly controls TCP Ports • Resource control • Protection from covert analysis

  10. Communication Subsystem • Interfaces • Text • Email/S-MIME • HTTPS • Presently controls Scheduling • Voting Functionality • Posts Contracts • Public Record

  11. Election Subsystem • Allocates Resources • Creates new UID's • Centerpoint for threshold keys

  12. Initial Configuration • Defines Startup Contracts • User Addition/Deletion • Resources Allocation • Initial Groups • Change Thresholds

  13. User Addition • Voted in • Private filesystem • Resource allocation(decided at initial) • Private key never exists on system. • User posseses inviolate filesystem • No UID except user allowed • Encrypted

  14. Group Creation • Control resides within communication subsystem • Group is a unique UID • Can be threshold or single user controlled • Resources allocated from users • Voting parameters

  15. Contracts • Contract resides in communication subsystem • Shell script • Signed by group

  16. Configuration Issues • De-allocation of resources • Accountability vs. Logging Privacy • Controls for system shutdown

  17. Design Issues • Reboot • Hierarchical groups • Resource alocation algorithms • Contiuity assurance • Contract "language" • Power limitation of groups • Re-Keying for user addition
