摘要

Network real-time applications are gaining rapid prominence on today's Internet, particularly video and audio streaming, conferencing and telephony applications. The original design of those applications and their corresponding protocols did not consider security and privacy, which form a compelling requirement to many of the Internet users and in many of the involved applications. One of the most common solutions to impose security on net- work traffic is to use the IPSec security protocol, which adds authentication and encryption to network packets, by which securing network applications. In the context of time-sensitive application such as VoIP and similar real- time applications, an important question that arises is how, if any, the overhead of IPSec operations could affect the performance of network applications. This paper surveys a number of the most relevant works that ad- dressed this question mostly within the last decade. The approach, metrics and findings of each study are briefly described and an overall summary of their main characteristics is presented.
