With the advent of low cost wireless chipsets, wireless mesh networks became much more attractive for both companies, governments, and the general consumer. This talk will describe the FreeBSD implementation of 802.11s.

Wireless mesh networks are being used extensively since the popularization of the 802.11 wireless technologies, but usually they worked with the help of layer 3 routing technologies. Since 802.11 didn't provide any kind of support for wireless mesh networks, in 2004, IEEE created the Task Group s (TGs) to create a new amendment to 802.11 which would define the operation of a wireless mesh network using existing 802.11 hardware and having a routing protocol work at layer 2. Later, the amendment also included provisions for mesh authentication, encryption, link management, bridging mesh networks with other types of networks, and channel reservation.

On this lecture I will talk about the FreeBSD implementation of 802.11s that's available in version 8.0 and beyond. This work was sponsored by The FreeBSD Foundation.

Everything you need to know about cryptography in 1 hour

Cryptography is hard. It usually takes many years of study before it is possible to make any serious contribution to the field; and even expert cryptographers often have flaws discovered in their work.

However, merely using cryptography requires far less expertise. In this talk, I will cover everything most software developers will ever need to know about cryptography -- starting from the very beginning -- along with (time allowing) some of the reasons behind the recommendations I provide.

Specific topics covered will include symmetric vs. asymmetric encryption; symmetric vs. asymmetric signatures; block ciphers; block cipher modes; key lengths; message authentication codes; hash algorithms; password handling; padding for asymmetric encryption; padding for asymmetric signing; Diffie-Hellman groups; and side channel attacks. Specific attacks will be discussed only to the extent of mentioning that they exist and explaining how cryptography-using systems should be designed to thwart them.
