Venue & Time : Aula Alfa, 113 Via Salaria. 3:00 PM
Abstract : Traditional security services are supported by a
fixed centralized infrastructure (such as CAs in a
PKI). However, in certain settings (e.g., MANETs and
Sensor Networks), such an infrastructure might be
unavailable or impractical. Providing extensible
distributed security services -- such as key
establishment and signing (certification) -- is a
formidable problem due to unreliable communication,
volatility of the nodes and their limited
resources. The main challenge is how to efficiently
establish secure communication channels and provide
distributed and fault-tolerant security services,
e.g., a distributed certification authority.
In the first part of the talk, I present distributed
cryptographic protocols that provide efficient
extension of secure network membership. In
particular, I show how (public-key based) secure
communication among a dynamic group of nodes can be
achieved without public key certificates. In the
second part of the talk, I focus on distributed
(proactive/threshold) RSA signature
schemes. Specifically, I present a practical
key-recovery attack on a well-known RSA-based
scheme, and show how to build an efficient provably
secure proactive RSA on top of it.
Please feel free to extend this invitation to other interested people.
