Chinese Company: Skype Protocol Cracked.
Skype is dismissing a claim by a small team of Chinese engineers who say
they have reverse engineered the protocol used for Skype Internet phone
The development is being reported by Charlie Paglee, the chief executive
officer of Vozin Communications, a voice-over-IP company that offers the
Talqer plug-in for Google Talk, and which has operations in China and
California. Paglee, a Mandarin speaker who has worked in China since
1987, said he knows the people in the small company who reverse
engineered the Skype protocol.
Paglee wrote about the reverse engineering on his blog, and said he has
been asked not to reveal the name of the company that reverse engineered
The 10-person Chinese company, which has received venture capital
funding, is planning to release in two weeks three software components
based on the Skype protocol that would allow developers to create
compatible applications, Paglee said. Those components comprise voice
and instant-messaging functions, he said.
Skype’s protocol is proprietary, so third party developers have not been
able to build compatible applications. Some other voice-over-IP
applications are based on the open Session Initiation Protocol standard,
enabling third-party developers to create interoperable products.
Skype, a unit of eBay, said Friday it is aware of the claim but had "no
evidence to suggest that this is true."
"Even if it was possible to do this, the software code would lack the
feature set and reliability of Skype," according to a statement from
Skype. "Moreover, no amount of reverse engineering would threaten
Skype’s cryptographic security or integrity."
