Summary : EADS,EADS
Skype is a free voice over IP (VOIP) application. This presentation covers the many layers of protection, tools and techniques that have been used to protect Skype internals. While many other VOIP applications exist specific traits make Skype very different, such as its peer-to-peer architecture, its ease to bypass firewalls and the impressive level of obfuscation that has been invested to prevent anybody from looking inside the software and its communications. This last point added to its increasing success while giving to many myths on security issues around it.
