技术领域
本申请一般涉及数字内容的分发。更具体地，本申请涉及基于清单和消息认证代码从具有有限资源的装置将内容的签名委托给计算强大的装置。
背景技术
互联网和电子商务的激增继续产生大量的数字内容。设计出内容中心网络(CCN)架构来促进访问并处理这些数字内容。CCN包括实体或装置，诸如网络客户端、转发器(例如路由器)和内容生产者，他们通过发送对各种内容项目的兴趣包并接收返回的内容对象包来彼此通信。CCN兴趣和内容对象由其唯一的名称标识，该唯一的名称通常是分层结构的可变长度标识符(HSVLI)。HSVLI可以包括从最概括级到最具体级排序的连续名称组成。每个CCN内容对象可以由其生产者或发布者以加密方式签名，例如通过基于不对称或公钥加密术创建电子签名。请求客户端可以验证所接收的内容的数字签名，以保证完整性、原始身份验证和正确性。然而，产生数字签名可能计算量很大。一些装置(例如物联网(IoT)或传感器网络应用)由于有限的存储器、计算能力或能量供应可能缺少产生数字签名的资源。
发明内容
一个实施例提供一种在CCN中委托签名产生的系统。操作中，系统通过第一内容生产装置监视由第二内容生产装置发布的一个或多个内容对象，其中，内容对象通过名称标识，所述名称为包括从最概括级到最具体级排序的连续名称组成的分层结构可变长度标识符(HSVLI)。第一装置检索一个或多个内容对象。响应于确定检索的内容对象指示消息认证代码，第一装置基于被第一和第二装置共享的密钥认证检索的内容对象的消息认证代码。第一装置创建对清单名称和每个检索的内容对象的内容对象散列(COH)值进行指示的清单。第一装置基于第一装置的私钥为清单产生数字签名，并在清单中包括数字签名，从而促进将由第二内容生产装置发布的内容对象的签名产生委托给第一内容生产装置。
在一些实施例中，响应于确定检索的内容对象不指示消息认证代码，第一装置基于以下一个或多个认证检索的内容对象：所述第一内容生产装置和所述第二内容生产装置的物理位置；以及网络拓扑。
在一些实施例中，所述清单的名称在检索的内容对象中指示。
在一些实施例中，所述第一装置基于以下的一个或多个检索所述一个或多个内容对象：与所述一个或多个内容对象中的每一个关联的名称；以及所述一个或多个内容对象中的每一个的内容对象散列(COH)值。
在一些实施例中，所述清单还指示每个检索的内容对象的名称。
在一些实施例中，所述一个或多个内容对象中的每个指示名称。
在这些实施例的另一种变形中，操作中，所述系统能够通过第二内容生产装置生成指示消息认证代码的一个或多个内容对象，所述消息认证代码基于由所述第二内容生产装置和第一内容生产装置共享的密钥，其中，内容对象通过名称标识，所述名称为包括从最概括级到最具体级排序的连续名称组成的分层结构可变长度标识符(HSVLI)。所述系统将所述一个或多个内容对象的数字签名的产生委托给所述第一内容生产装置。
在一些实施例中，由所述第二内容生产装置生成的所述一个或多个内容对象中的每一个指示名称。
在一些实施例中，所述系统通过以下将数字签名的产生委托给所述第一内容生产装置：由第一内容生产装置基于共享密钥认证所述一个或多个内容对象的MAC；创建对一个或多个内容对象和所述一个或多个内容对象中每一个的COH值进行指示的清单；基于所述第一内容生产装置的私钥产生所述清单的数字签名；以及在所述清单中包括数字签名。
在一些实施例中，所述一个或多个内容对象还指示要由所述第一内容生产装置创建的清单的名称。
在一些实施例中，由所述第一内容生产装置创建的清单指示所述一个或多个内容对象和所述一个或多个内容对象中每一个的内容对象散列(COH)值。

具体实施方式
给出以下描述使得本领域技术人员能够制造和使用实施例，以下描述是在特定应用和其需求的背景下提供的。对所公开实施例的各种改进对本领域技术人员是非常显然的，在不偏离本发明的精神和范围下，本文中定义的通用原理可以应用于其它实施例和应用。因此，本发明不局限于所显示的实施例，而是给予与本文中公开的原理和特征一致的最宽范围。
本发明的实施例提供一种系统，其通过将内容的数字签名产生委托给计算功能更强的装置，解决了对资源有限的装置创建的内容进行认证的问题。在CCN中，内容可以由内容的生产者数字签名，使得接收内容的实体(例如请求客户端应用)可以通过验证数字签名来认证内容。特别是基于公钥或不对称加密的数字签名产生可能是计算量很大的。结果，一些装置可能没有资源来对产生的内容进行数字签名。例如，在桥中用于探测结构条件的传感器装置或物联网(IoT)装置，象Fitbit或SmartWatch可能产生网络上的另一实体希望检索的内容。然而，这些传感器和IoT装置可能存储容量、计算能力和电池供电有限，这还可能限制这些“简单”装置对其内容进行数字签名的能力。
本系统允许简单装置(例如具有有限资源的内容生产者)将签名产生委托给计算能力更强的装置(例如内容发布者)。简单装置和内容发布者共享基于密钥交换协议(例如对称加密)分发的私钥。简单装置创建内容对象，并使用共享私钥，包括每个内容对象的基于散列的消息认证代码(HMAC)。可以通过将加密散列函数与共享私钥结合应用到内容对象来计算HMAC。发布者可以通过基于相同的加密散列函数和共享密钥计算HMAC并将计算的HMAC与包括的HMAC进行比较来验证内容的完整性和身份验证。发布者然后可以创建对被认证的所有内容对象进行指示的清单，对清单进行数字签名以及通过CCN发布清单。通过使用安全内容目录(例如清单)签名和验证内容对象的集合在美国专利申请号14/231,515中描述。因此，通过使用HMAC和清单，将签名产生委托给内容发布者取消了简单内容生产装置认证其内容的必要。
在本申请描述的示例中，每项内容是分别被命名的，每项数据被绑定到将该数据与任何其它项数据相区分的唯一名称，诸如相同数据的其它形式或来自其它源的数据。此唯一名称允许网络装置通过传播指示唯一名称的请求或兴趣来请求数据，可以获得与数据的存储位置、网络位置、应用和传输手段无关的数据。以下词语用来描述CCN架构：
内容对象(ContentObject)：单一一项命名数据，其绑定到唯一名称。内容对象是“永久的”，这意味着内容对象可以在计算装置内或者在不同的计算装置中移动，但不会改变。如果内容对象的任何组成变化，则出现变化的实体创建包括更新内容的新内容对象，并且将新内容对象绑定到新唯一名称。
唯一名称(UniqueName)：CCN中的名称通常是与位置无关的，唯一地标识内容对象。数据转发装置不管内容对象的网络地址或物理位置如何，可以使用名称或名称前缀将包向生成或存储内容对象的网络节点转发。在一些实施例中，名称可以是层次结构的可变长度标识符(HSVLI)。HSVLI可以分成几个层次组成，这些组成可以以各种方式构造。例如，个别的名称组成parc,home,ccn,和test.txt可以以左对齐的前缀为主的方式构造，形成名称“/parc/home/ccn/test.txt”。因此，名称“/parc/home/ccn”可以是“/parc/home/ccn/test.txt”的“父”或“前缀”。附加组成可以用来区分内容项目的不同形式，诸如合作文档。在一些实施例中，名称可以包括不分层标识符，诸如从内容对象的数据(例如验证和值)和/或从内容对象的名称的元素导出的散列值。基于散列的名称的描述在美国专利申请号13/847,814中描述。名称还可以是扁平标签。后文中“名称”用来指名称数据网络中的一条数据的任何名称，诸如层次名称或名称前缀、扁平名称、固定长度的名称、任意长度的名称或标签(例如多协议标签交换(MPLS)标签)。
兴趣(Interest)：指示对一条数据的请求的包，包括该条数据的名称(或名称前缀)。数据消费者可以在信息中心网络中传播请求或兴趣，CCN路由器可以向可以提供所请求数据以满足请求或兴趣的存储装置(例如缓存服务器)或数据生产者播送。
本文中公开的方法不局限于CCN网络，也适用于其它架构。CCN架构的一个示例在美国专利申请号12/338,175中描述。
图1图解说明根据本发明的实施例促进将认证签名产生委托给内容发布装置的示例性计算环境100。在本申请中，“内容生产者”指创建任何类型的内容(例如照片、传感器采集数据等)的实体，而“内容发布者”指将内容生产者产生的数据转换成具有关联加密身份的清单(例如内容对象)并通过CCN发布清单的实体。计算环境100可以包括内容生产者104和内容发布者106。网络102可以是内容中心网络(CCN)、命名数据网络(NDN)或信息中心网络(ICN)。
内容生产者104可以产生内容对象120，内容对象120包括名称、有效载荷和散列消息认证代码(HMAC)。内容生产者104可以是具有有限资源的简单装置(例如传感器)，其缺少生成它产生的内容的数字签名的资源。不是对内容对象120进行数字签名，内容生产者104可以基于散列函数和与内容发布者106共享的密钥为内容对象120(例如每个内容对象120.1-120.m)创建HMAC。内容生产者104可以包括HMAC作为内容对象120的一部分。
内容发布者106可以通过网络102监视内容对象120。内容发布者106可以通过基于散列函数和密钥计算每个内容对象的HMAC并随后将计算的HMAC与包括的HMAC进行比较来验证内容对象120的完整性和真实性。一旦基于HMAC验证内容，内容发布者106可以创建具有名称132的清单130。清单130可以通过其名称和内容对象散列(COH)值指示每个内容对象120.1-120.m。内容发布者106可以为清单130产生数字签名134，并在清单130中包括签名134。因此，系统允许希望获得内容对象120的实体(例如内容消费者108)检索认证的验证清单(例如由内容发布者106数字签名并包含已经基于HMAC和共享密钥认证的内容对象120的清单130)，而不需要简单的内容生产装置104创建其自己的数字签名。
图2A-2E呈现对由内容生产装置创建的内容对象的格式进行描绘的表。图2A呈现根据本发明的实施例描绘内容对象220的格式的表。内容对象220可以包括名称202、有效载荷204和基于散列的消息认证代码(HMAC)208。HMAC208是基于加密散列函数和与另一实体(例如内容发布者)共享的密钥创建的。
图2B呈现根据本发明的实施例描绘内容对象230的格式的表。与内容对象220类似，内容对象230可以包括名称202、有效载荷204和HMAC208。内容对象230还可以包括清单名称206，其指示内容发布者命名验证的签名清单时使用的名称。清单名称206可以包括于内容对象230的密钥定位器字段(未显示)中。
图2C呈现根据本发明的实施例描绘内容对象240的格式的表。内容对象240包括有效载荷204和HMAC208，但不包括名称。无名称内容对象可以通过其内容对象散列(COH)值检索，如美国专利申请号14/337,026中描述的。
图2D呈现根据本发明的实施例描绘内容对象250的格式的表。内容对象250包括名称202和有效载荷204，但不包括HMAC。当内容生产者和内容发布者位于共同的物理位置或基于网络拓扑，可以直接相互通信时，共享密钥认证(例如通过HMAC)是不需要的。例如，当生产者与发布者通过蓝牙或物理线或电缆通信时，由于生产者和发布者是直接连接的，系统不需要认证由生产者创建的内容。
图2E呈现根据本发明的实施例描绘内容对象260的格式的表。内容对象260只包括有效载荷204。系统可以使用内容对象260作为无名称对象(类似于内容对象240)，而不使用HMAC，原因是例如生产者和发布者的物理共同位置(类似于内容对象250)。
图3A呈现根据本发明的实施例描绘内容发布装置创建的清单300的格式的表。清单300是可以包括名称302、有效载荷304和清单300的发布者的签名310的内容对象。有效载荷304可以通过其名称306.1-306.n和其内容对象散列(COH)值308.1-308.n指示内容对象的集合。在一些实施例中，名称302对应于清单300中指示的内容对象中包括的清单名称。例如，名称302可以对应于图2B中的内容对象230的清单名称206。
图3B呈现根据本发明的实施例描绘由内容发布装置创建的清单320的格式的表。与清单300类似，清单320包括名称322、有效载荷324和清单320的发布者的签名330。有效载荷324可以只通过其COH值308.1-308.n而不通过其名称指示内容对象的集合。通过其COH值的无名称内容对象的检索在美国专利申请号14/337,026中描述。
图4呈现对根据本发明的实施例内容生产装置创建内容的方法400进行图解说明的流程图。操作中，内容生产装置创建内容对象(操作402)，并包括每个内容对象的名称(操作404)。在一些实施例中，内容对象不包括名称(例如参照图2C和2E描述的)。内容生产装置基于与内容发布装置共享的密钥为每个内容对象创建消息认证代码(操作406)。消息认证代码可以是基于散列的消息认证代码(HMAC)。内容生产装置在内容对象中包括消息认证代码(操作408)。在一些实施例中，内容对象不包括消息认证代码(例如参照图2D和2E描述的)。内容生产装置可以将签名产生委托给内容发布装置(操作410)。
图5示出对根据本发明的实施例由内容发布装置对内容生产装置创建的内容进行认证的方法500进行图解说明的流程图。操作中，内容发布装置监视由内容生产装置创建的内容(操作502)。内容发布装置基于名称和每个内容对象的内容对象散列(COH)值检索内容对象(操作504)。如果内容对象包括消息认证代码(例如参照图2A-2C描述的HMAC)(判断506)，则内容发布装置基于与内容生产装置共享的密钥认证每个内容对象的HMAC(操作510)。如果内容对象不包括消息认证代码(例如参照图2D和3E描述的)，内容发布装置基于物理共同位置或网络拓扑认证内容对象(操作508)。例如，如果装置之间相互直接连接，则内容生产装置不需要为每个内容对象创建消息认证代码，以用于由内容发布装置进行认证。一旦认证内容对象，内容发布装置基于每个内容对象的名称和COH值创建内容对象的清单(操作512)。在一些实施例中，清单只通过COH而不通过名称指示内容对象(例如参照图3B描述的)。内容发布者产生清单的数字签名(操作514)，并在清单中包括数字签名(操作516)，因此为例如类似随后获得清单的内容消费者的CCN实体提供对内容生产装置创建的内容对象的认证。
图6图解说明根据本发明的实施例促进认证签名产生的委托的示例性计算机和通信系统602。计算机和通信系统602包括处理器604、存储器606和存储装置608。存储器606可以包括充当管理存储器的易失性存储器(例如RAM)，并且可以用来存储一个或多个内存池。而且，计算机和通信系统602可以耦连到显示装置610、键盘612和定位装置614。存储装置608可以存储操作系统616、内容处理系统618和数据632。
内容处理系统618可以包括指令，这些指令在由计算机和通信系统602执行时，可以引起计算机和通信系统602执行本申请中描述的方法和/或过程。具体地，内容处理系统618可以包括用于监视内容对象的指令(监视机构622)。内容处理系统618还可以包括用于检索内容对象并使内容对象在CCN中可用的指令(通信机构620)。内容处理系统618还可以包括用于确定内容对象是否包含消息认证代码并随后基于消息认证代码或物理拓扑认证内容对象的指令(认证机构624)。
此外，内容处理系统618可以创建对内容对象和其对应的内容对象散列(COH)值进行指示的清单(清单创建机构626)。内容处理系统618还可以包括用于基于目录的生产者的私钥产生清单的数字签名的指令(签名产生机构628)。内容处理系统618可以包括用于基于目录生产者的公钥验证安全内容目录的数字签名的指令(签名验证机构626)。
而且，内容处理系统618可以包括用于基于共享密钥生成指示消息认证代码的内容对象的指令(内容创建机构630)。内容处理系统618可以包括用于将签名产生委托给内容发布装置的指令(签名产生机构628)。
数据632可以包括通过本申请中描述的方法和/或过程作为输入请求的或作为输出生成的任何数据。具体地，数据632可以存储至少：具有有效载荷的内容对象；内容对象的名称，其为包括从最概括级到最具体级排序的连续名称组成的分层结构可变长度标识符(HSVLI)；消息认证代码；基于散列函数和密钥的基于散列的消息认证代码；指示内容对象的集合的清单；内容对象散列(COH)值；关于装置的网络拓扑或位置的信息；清单名称；内容发布者的数字签名；以及由其名称或COH指示的内容对象的集合。
在此详细描述中描述的数据结构和代码通常存储于计算机可读存储介质上，计算机可读存储介质可以是可以存储代码和/或数据以由计算机系统使用的任何装置或介质。计算机可读存储介质包括但不限于易失性存储器、非易失性存储器、磁和光存储装置(诸如磁盘驱动器、磁带、CD(光盘)、DVD(数字通用盘或数字视频盘))或能够存储计算机可读介质的现在已知或以后开发的其它介质。
