Dear Colleague,

we cordially invite you to a RISC Seminar taking place on

                            *Wednesday September 25, 2013, at 1600h in
Room L017 at CWI*

The program features a talk by

                                     Erez Waisbard (Bar-Ilan University).

The talk is entitled

                      ``Efficient Signature Scheme for Network Coding''


The abstract is quoted below. See also http://www.cwi.nl/crypto/risc.html

See you then and there!

Best regards,
Ignacio Cascudo, Ronald Cramer and Serge Fehr

Efficient Signature Scheme for Network Coding

Network coding maximizes the network throughput. However, they are also
vulnerable to pollution attacks in which malicious forwarders inject
polluted messages into the system. Traditional cryptographic solution,
such as digital signatures, are not suited for network coding, in which
nodes do not forward the original packets, but rather linear
combinations of the data they received. We describe a new scheme that
uses batch techniques and selective verification to efficiently verify
the integrity of the received packets. We show that for real
peer-to-peer networks, our scheme is much more efficient than previously
suggested schemes.
Joint work with Ely Porat.
