| Abstract: |
In the digital world nowadays, multimedia security is becoming more and more
important with the continuous increase in the use of
digital communications on the Internet. In addition, special and reliable
security in storage and transmission of digital images and videos
is needed in many digital applications, such as pay-TV, con dential video
conferencing and medical imaging systems, etc.
Unfortunately, the classical techniques for data security are
not appropriate for the current multimedia usage. As a result, we need to
develop new security protocols or adapt the available security protocols to be
applicable for securing the multimedia applications.
Generally speaking, the well-developed modern cryptography should
be the perfect solution for this task. In this paper, we show that AES
algorithm can be used for securing real time video
transmission with little processing overhead over the
Internet. We support our study with exhaustive
comparison between AES and XOR encryption algorithms
with normal transmission. |
