SUMMARY:Better authentication: password revolution by evolution - Daniel T
 homas (University of Cambridge)

DESCRIPTION:Users authenticate in multiple security domains: at work\, at 
 home and to\nthird parties.\nThis is mostly done with passwords\, with sev
 eral shared across many domains.\nThis does not scale well when a device o
 r domain is compromised.\nWe would rather not trust systems not owned by t
 he user.\nThe problems with passwords are well known and yet they are not 
 replaced.\nWith protocols like SSH they are replaced by public-key cryptog
 raphy\nwhere one public SSH key is distributed to many security domains.\n
 However that does not work for physically proximate devices or in other\nc
 ontexts requiring password input.\nWe propose a one time token system base
 d on public keys that is\nbackwards compatible with passwords and hence de
 ployable.\nOur solution proposes a new verification function that does not
  trust\nthe verifier or expose the user to brute force attacks and allows 
 users\nto monitor their credentials and revoke access in the case of compr
 omise.\n\n\nThis is a practice talk for the Security Protocols Workshop\n(
 2014-03-19--2014-03-21) the maximum time including questions is half an\nh
 our and interruptions for questions are encouraged.
