传输过程总体来说： （1）客户端提供【客户端随机数、可选算法套件、sessionId】等信息 （2）服务端提供【服务端随机数、选用算法套件、sessionId】等信息 （3）服务端提供证书 （4）服务端与客户端互换算法需要的参数 （5）客户端根据前面提到的随机数和参数生成master secret，确认开始使用指定算法加密，并将握手信息加密传输给服务端，用来校验握手信息、秘钥是否正确 （6）服务端进行与（5）一样的操作 （7）客户端、服务端可以用master secret进行加密通讯 来源： https://www.cnblogs.com/lysblogs/p/11958915.html

Is there a tool for repairing RCS/CVS ,v files? [closed]

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I am doing a whole bunch of conversions of CVS and RCS repositories into Subversion. Every now and then I run into a damaged ,v file. I have figured out how to repair these manually, but it's getting tedious, and my latest project has numerous damaged files, more than I care to repair manually. So I'd like to have a tool to parse the RCS files and repair them. That may well mean some old versions will be

$id: name of file, date/time creation Exp $

问题 Frequently I come across the following statements in C/C++ source code: $Id: lzio.c,v 1.24 2003/03/20 16:00:56 roberto Exp $ $Id: file name, version, timestamp, creator Exp $ Have you got any idea which software produces those "signatures"? 回答1: Version control systems such as CVS can produce such tags. 回答2: Keyword substitution in subversion produces this sort of information, in particular Id: Id This keyword is a compressed combination of the other keywords. Its substitution looks something

Algorithm for efficient diffing of huge files

由 主宰稳场 提交于 2019-12-03 04:25:34
问题 I have to store two files A and B which are both very large (like 100GB). However B is likely to be similar in big parts to A so i could store A and diff(A, B). There are two interesting aspects to this problem: The files are too big to be analyzed by any diff library I know of because they are in-memory I don't actually need a diff - a diff typically has inserts, edits and deletes because it is meant to be read by humans. I can get away with less information: I only need "new range of bytes"

GSMA RCS架构

由 匿名 (未验证) 提交于 2019-12-03 00:42:01
由开放移动联盟（OMA）和GSM协会（GSMA）等主要标准组织制定的消息传送技术在架构和技术细节方面有许多相似之处。 OMA融合IP消息系统（CPM）从一开始就基于OMA SIMPLE IM进行设计. 因此重用了其大部分有关即时消息功能的详细技术。 GSMA丰富通信套件（RCS）在其早期版本中采用了OMA SIMPLE IM架构. 并且最近采用了OMA CPM架构来提供融合通信服务功能。 因此. RCS由许多具有最先进的服务特性. 协议和接口的功能组件组成. 本文将对此进行简要回顾。 GSMA富通信套件（RCS）最初基于OMA SIMPLE IM架构. 但采用了RCS r4.0的OMA融合IP消息系统（CPM）架构。 虽然RCS r4.0更新至RCS 5.0及以上版本. 但整合了更多的服务特性和更详细的技术要点. 但其架构本身保持不变。 SIMPLE IM和CPM之间的概念区别在于SIMPLE IM专注于在SIP / IP核心上实现IP消息传递功能. 而CPM侧重于如何实现不同通信技术中的融合用户体验. 例如IP消息传递 . 语音. 视频等。在CPM架构之上. RCS已经指定了内容共享. 位置信息共享和社交呈现信息共享等附加增值服务功能. 反映了近期许多社交网络服务已经证明的市场需求。 SIMPLE IM启动器由IM客户端，IM服务器和IM XML文档管理服务器（XDMS）组成。

GSMA RCS标准的演变

由 匿名 (未验证) 提交于 2019-12-03 00:42:01
市场需求推动了丰富通信服务技术标准的发展.开放移动联盟（OMA）基于IMS和SIP技术指定了SIMPLE IM和融合IP消息系统（CPM）的技术细节.这种技术的概念反映了2000年代中期左右流行的基于PC的消息传送服务.自2000年代后期左右智能手机时代以来、以运营商为中心的生态系统开始崩溃、许多OTT（Over-The-Top、通信服务）通信服务开始在市场上以其免费短信和语音通话服务起飞、从而威胁到传统 运营商的收入.运营商通过提出GSMA指定的丰富通信套件（RCS）技术来应对这些威胁.RCS的标准仍在不断发展、其中纳入了上市时间服务功能的各种要求、并考虑了商业模式。 当GSM协会（GSMA）于2011年4月首次指定富通讯套件演变（RCSe）标准、品牌名称为“Joyn”时、许多全球电信公司预计Joyn可能成为与现有和突出OTT服务、如Whatsapp、Viber、Line等。从运营商的角度来看、这些OTT服务通过搭载电信公司的既有基础设施而大幅增长、他们甚至通过免费提供免费电话服务的收入来源mVoIP和消息服务功能。在韩国、三大电信公司（即SKT、KT和LG U +）于2012年底开始提供Joyn服务、而在欧洲、特别是西班牙和德国、沃达丰和Orange等全球性公司也开始提供相同的服务。从那时起已经差不多三年了。与最初的猜测不同的是、这些国家的Joyn服务并没有得到很大的普及
