CoolTech Club with Ian McPherson : Untangling the mesh network - A practical examination

WHEN

July 28,2004

WHAT

From sensor and control networks to public safety systems, vendors are touting mesh networks as the next revolution in wireless communications.  We will discuss the different approaches to mesh networking, the challenges, as well as the market segments where this approach is gaining traction

CoolTech Club with Philip de Louraille : Worm Rising

WHEN

June 30,2004

WHAT

Worm activity is swamping IDS sensors. Smart, dedicated and focused hackers can use worm attacks to their advantage to mask and hide their activity. What's an Information Security team to do to keep an eye both on the storms of activities triggered by the worms and on the activities of a lone hacker who is not triggering that many bells?

CoolTech Club with Oleg Zabluda : Security and Cryptography. Relationship between the two (Part II)

WHEN

February 11, 2004

WHAT

  • Public key cryptography (RSA, PGP). Hybrid cryptosystems.
  • Real stream ciphers. Corresponding block cipher modes, OFB, CTR. RC4. Why 802.11b security is a joke.
  • Authentication. Man-in-the-middle attack. Interlock protocol.
  • Symmetric key authentication (MAC, CBC-MAC, HMAC, Kerberos).
  • Public key authentication (RSA/PGP digital signatures)
  • PKI. Why it sucks.
  • SSL.

What They Say About Us

"The wonderful thing about entrepreneurs is that their passion for starting new companies transcends languages and geographic boundaries."

Ron Conway, Founder and Managing Partner of the Angel Investors LP funds, early stage investor in Google and PayPal

"Networking is very important for start-ups. The challenge for them is often not money: it is mentoring and finding people who can give good advice from experience."

Esther Dyson, Founder, EDventure Holdings

"This conference is clearly a labor of love for a group of dedicated professionals who care deeply about the Eastern European entrepreneurs. From the value-packed educational panels, to the star-studded key note speakers' line up, to an amazing quantity of venture capitalists – this is a not to be missed event for any high tech entrepreneur,"

Richard Guha, President of the Marketing Executives Network and Managing Partner at MaxBrandEquity

"As Stanford MBA students, we were exposed to a lot of VC firms both from the Valley and abroad. It is at Stanford that we met Anna Dvornikova, an absolutely amazing business leader and (by our big luck) our friend, who was the center of the Russian Silicon Valley professional community, and was doing a huge work to connect Russia and the Valley. Anna helped us a lot with kick-starting Wikimart, put us to our first-ever conference, introduced us to most of Russian VCs. And all that happened in a very short time span! It was the beginning of a six-month journey that despite the particularly tough times resulted in an extraordinarily group of investors backing our start-up."

Maxim Faldin and Kamil Kurmakayev,
co-CEOs, Wikimart
