Subject: [risc-list] RISC at CWI (Dec 13): Tiloca

Dear Colleague,

we cordially invite you to a RISC Seminar taking place on

                            *Friday December 13, 2013, at 1600h in Room 
L017 at CWI*

The program features a talk by

                                     Marco Tiloca (ICT SICS Stockholm).

The talk is entitled

                      ``SMACK: a security extension for the Constrained 
Application Protocol''.


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

See you then and there!

Best regards,
Ronald Cramer, Serge Fehr and Marc Stevens

SMACK: a security extension for the Constrained Application Protocol

Abstract: Internet of Things (IoT) commonly refers to the upcoming 
network society where all connectable devices will be directly connected 
to the Internet, and able to communicate with one another. Since many 
IoT devices are likely to be resource constrained and battery powered, 
they are particularly vulnerable to Denial of Service (DoS) attacks 
specifically aimed at quickly draining battery energy, and severely 
reducing device lifetime. In order to address this issue, we have 
designed SMACK, a security extension for the Constrained Application 
Protocol (CoAP), that efficiently identifies invalid messages upon their 
reception by early checking a short Message Authentication Code (MAC). 
Thanks to SMACK, it is possible to avoid further useless processing of 
invalid messages, hence reducing the impact of DoS attacks, and 
preserving device battery life. SMACK is compliant with CoAP 
specification, does not alter the original message format, and can 
easily work together with additional reaction mechanisms against DoS 
attacks.

Bio: Marco Tiloca received his Bachelor's Degree and Master's Degree in 
Computer Engineering from the University of Pisa, Pisa, Italy, in 2006 
and 2009, respectively. He received his Ph.D. in Computer Engineering 
from the "Department of Information Engineering" of the University of 
Pisa, in 2013. Currently, he is a Postdoctoral Research Fellow at 
Swedish ICT SICS in Stockholm, Sweden, under the ERCIM/Marie Curie 
Fellowship Programme. His research interests are in the field of network 
security with particular reference to constrained devices, and include 
key management and secure group communication. Currently, he is working 
on security in the Internet of Things.
