Levels of Trust

• Trust Interaction

• • Carol (f/f)
  • Alice (u/u) Tom (f/f) Katy (f/f) Jeff (-/-)
  • Greg (-/f)
  • Sandra (-/f)
  • Example #5
  • A fully trusted key will introduce a fully validated key:
  • -Carol's key fully validates Tom's key.
  • -Tom's key can now fully validate Sandra's and Katy's keys.
  • Katy's key fails to validate Jeff's key due to path length.
