DomainKeys Identified Mail (DKIM) provides a cryptographic mechanism
for domains to assert responsibility for the messages they handle. A
related mechanism will allow an administrator to publish various
statements about their DKIM signing practices. This document defines
requirements for this mechanism, distinguishing between those that
must be satisfied (MUST), and those that are highly desirable
(SHOULD).,2010-12-15 16:21:27,下载2次
rfc5015.txt.rar - This document discusses Bidirectional PIM (BIDIR-PIM), a variant of
PIM Sparse-Mode that builds bidirectional shared trees connecting
multicast sources and receivers. Bidirectional trees are built using
a fail-safe Designated Forwarder (DF) election mechanism operating on
each link of a multicast topology. With the assistance of the DF,
multicast data is natively forwarded from sources to the Rendezvous-
Point (RP) and hence along the shared tree to receivers without
requiring source-specific state. The DF election takes place at RP
discovery time and provides the route to the RP, thus eliminating the
requirement for data-driven protocol events.,2010-12-15 16:20:39,下载1次

This document describes a means for automated, authenticated, and
authorized updating of DNSSEC "trust anchors". The method provides
protection against N-1 key compromises of N keys in the trust point
key set. Based on the trust established by the presence of a current
anchor, other anchors may be added at the same place in the
hierarchy, and, ultimately, supplant the existing anchor(s).
This mechanism will require changes to resolver management behavior
(but not resolver resolution behavior), and the addition of a single
flag bit to the DNSKEY record.,2010-12-15 16:07:27,下载2次

This memo defines a new suboption of the Dynamic Host Configuration
Protocol (DHCP) relay agent information option that allows the DHCP
relay to specify flags for the forwarded packet. One flag is defined
to indicate whether the DHCP relay received the packet via a unicast
or broadcast packet. This information may be used by the DHCP server
to better serve clients based on whether their request was originally
broadcast or unicast.,2010-12-15 16:05:43,下载2次

In this document, we propose an extension to the BGP route selection
rules that would avoid unnecessary best path transitions between
external paths under certain conditions. The proposed extension
would help the overall network stability, and more importantly, would
eliminate certain BGP route oscillations in which more than one
external path from one BGP speaker contributes to the churn.,2010-12-15 15:58:46,下载2次

rfc5001.txt.rar - Abstract
With the increased use of DNS anycast, load balancing, and other
mechanisms allowing more than one DNS name server to share a single
IP address, it is sometimes difficult to tell which of a pool of name
servers has answered a particular query. While existing ad-hoc
mechanisms allow an operator to send follow-up queries when it is
necessary to debug such a configuration, the only completely reliable
way to obtain the identity of the name server that responded is to
have the name server include this information in the response itself.
This note defines a protocol extension to support this functionality.,2010-12-15 15:48:29,下载4次

A.Blind.MPEG-2.Video.Watermarking.Robust.to.Regula - Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and
extraction of the watermarks are done in the compressed domain.
The mean of the low-frequency DCT coefficients of the video is
temporally modulated according to the information bits. To
reduce complexity, we embed watermark in the prediction error
signals of the B-frames. Experimental results show that the
proposed scheme achieves high video quality and robustness to
camcorder recording, trans-coding, frame-rate conversion, and
geometric attacks on common test videos.,2010-12-15 15:36:51,下载12次
A.Blind.and.Robust.Watermarking.Scheme.rar - Abstract- H.264/AVC is becoming a popular video codec for
its better compression ratio, lower distortion and applicability
to portable electronic devices. Thus, issues of copyright
protection appropriate for this standard become very
important. In this paper, a new blind SVD (Singular Value
Decomposition) - DCT combined video watermarking scheme
for the ".264 standard is proposed. The proposed method is a
blind watermarking algorithm as the hidden information can be
extracted without the original video and the original singular
values. To reduce visual quality degradation caused by
coefficients modifying, the perceptual model and block selection
mechanism are introduced to control the modification strength.
The performance of the proposed algorithm is evaluated with
respect to imperceptibility, robustness and data payload.
Experimental results reveal that the proposed scheme achieves
enough robustness while preserving the perceptual quality.,2010-12-15 15:34:53,下载20次
