PAMPA

Password Authentication and Methods for Privacy and Anonymity

This 4-year fundamental research project has been launched within ANR SeSur and is a collaboration between EADS, ENS and Cryptolog.

Project outline

• WP0 - Project Management (leader EADS)
• WP1 - Password-based authentication (leader ENS)
• WP1.1 - Security models
• WP1.2 - Advanced password-based techniques
• WP1.3 - Password-based authentication for groups
• WP2 - Anonymity & Privacy (leader ENS)
• WP2.1 - Anonymous password-based authentication
• WP2.2 - Group signatures
• WP2.3 - (Traceable) anonymous encryption
• WP3 - Implementation (leader Cryptolog)
• WP3.1 - Performance measurements
• WP3.2 - Use cases and specification of a demonstrator
• WP3.3 - Demonstrator

Project planning

• First phase: administrative kick-off, state of the art
• Second phase: invention of new protocols, scientific publications
• Third phase: prototyping and demonstrators
