On improving multicast source authentication to achieve better security 基于消息認(rèn)證碼的組播源認(rèn)證研究
These restricts make source authentication difficultly accomplish in multicast environment 這使得在組播環(huán)境中進(jìn)行源認(rèn)證非常困難。
A novel video multicast instant source authentication model based on digital watermarking 一種基于數(shù)字水印的視頻多點(diǎn)廣播立即源認(rèn)證模型
In order to solve the problems of current source authentication methods, this thesis brings forward a new source authentication scheme based on the events sequence---- esa ( events sequence authentication ) . this scheme does not depend on the time synchronous mechanism, and it has the advantages of fast authentication and 根據(jù)現(xiàn)有源認(rèn)證方法的不足和存在問題,本文提出了基于事件序列的源認(rèn)證方案esa(eventssequenceauthentication),該方案不依賴時(shí)間同步機(jī)制,具有快速認(rèn)證,抗丟失性和擴(kuò)展性較好的特點(diǎn)。

From the research, we know that there has been no very good source authentication method which can satisfy the users " demands . the primary reason of no good method is higer requirement in multicast environment . we need efficient authentication even when there are packet loss and no senders " information 從本文對源認(rèn)證方法做的系統(tǒng)性研究可以得知,目前尚沒有很好的能滿足用戶需求的源認(rèn)證,其主要原因是由于在組播環(huán)境中對數(shù)據(jù)認(rèn)證有較高的要求,即需要在有包丟失、發(fā)送者不知道接收者狀態(tài)的情況下,高效的認(rèn)證數(shù)據(jù)包。
This thesis detailedly researches into source authentication, introducing and analyzing some previous source authentication methods . it analyzes a source authentication method ( tesla ) which is being paid more and more attention nowadays, its function, shortcoming and current improvement, and points out its secure vulnerability . we draw a conclusion : though tesla has many advantages, such as the low communication cost, tolerance of pack loss, there are still many problems, which mostly arise from the requirement of synchronous time 并對其中一種目前廣泛受到人們關(guān)注的源認(rèn)證方法tesla協(xié)議進(jìn)行了研究,包括對tesla的功能、原理、缺陷以及現(xiàn)有的改進(jìn)做了分析,指出其中的安全漏洞,并得到以下結(jié)論:盡管tesla有許多優(yōu)點(diǎn),如低通訊成本,較好的抗丟失性,但它仍然存在許多難以克服的缺陷,而這些問題主要是由于tesla所依賴的時(shí)間同步機(jī)制在現(xiàn)有網(wǎng)絡(luò)環(huán)境下不易實(shí)現(xiàn)所帶來的。
