Human-Usable Password Schemas: Beyond Information-Theoretic Security
Elan Rosenfeld, Santosh Vempala, Manuel Blum
Password users frequently employ passwords that are too simple, or they just reuse passwords for multiple websites. A common complaint is that utilizing secure passwords is too dif…
Towards Human Computable Passwords
Jeremiah Blocki, Manuel Blum, Anupam Datta +1
An interesting challenge for the cryptography community is to design authentication protocols that are so simple that a human can execute them without relying on a fully trusted co…
GOTCHA Password Hackers!
Jeremiah Blocki, Manuel Blum, Anupam Datta
We introduce GOTCHAs (Generating panOptic Turing Tests to Tell Computers and Humans Apart) as a way of preventing automated offline dictionary attacks against user selected passwor…
Naturally Rehearsing Passwords
Jeremiah Blocki, Manuel Blum, Anupam Datta
We introduce quantitative usability and security models to guide the design of password management schemes --- systematic strategies to help users create and remember multiple pass…
