Description

用于多播-广播-多媒体系统(MBMS)的安全注册
技术领域
本发明通常涉及电信，并且尤其涉及通信系统中的安全。
背景技术
在承载非语音业务(比如除了语音业务以外的视频、数据、多媒体或者其它类型业务)的无线通信系统里，如果在基站的覆盖区域以内，点播服务的用户数量超过预定阈值数，典型的蜂窝基站可以广播多媒体业务服务。这种多媒体业务服务可以是事件的视频流，比如体育事件、体育事件的精彩部分。如果在所述覆盖区域内没有足够的用户点播这一服务，基站就通过专用信道将所述服务仅仅发射给已经点播该服务的特定用户，而不是将该服务广播给该覆盖区域内的所有用户。
有时恶意用户或者非法用户例如可能通过采用多个不同身份在空闲模式进行多次注册，试图迫使基站将所述服务广播给覆盖区域内的所有用户。如果一个或者多个恶意用户利用处于空闲模式中的移动电话在覆盖区域内注册多次以接收事件的内容，则基站会将这些注册的数目作为该事件的合法用户注册进行计数，并将该事件广播给所述覆盖区域内的所有用户。
因此，在本领域中，网络运营商或者内容提供商需要具有可靠的装置(means)来进行如下验证，即只对覆盖区域内多媒体事件的合法注册进行计数，而不会由于虚假注册而被迫将所述事件广播给所述覆盖区域内的所有用户。
发明内容
在这里公开的实施例通过利用临时注册密钥(RGK)在多播-广播-多媒体系统(MBMS)中获得安全注册的一种方法和装置来解决上述需要。
附图说明
图1是说明多播-广播-多媒体系统(MBMS)通信链路的一个示例性方框图；
图2是说明该MBMS中安全注册的一个实施例的示图；和
图3是说明该MBMS中安全注册的另一个实施例的示图。
发明详述
在这里，单词“示例性的”在这里用作意味着“用作一个实例、示例和图例”。在这里作为“示例性的”描述的任何实施例不必被解释为相比其他实施例优选或者具有优势。在发明详述中描述的所有实施例都是示例性的实施例，其被提供来使得本领域里的技术人员能够实施或使用本发明，而不是限制本发明的保护范围，本发明的保护范围由权利要求限定。
移动台，也称作用户设备(UE)，可以与一个或者多个基站通信。移动台通过一个或者多个基站将数据分组发射给基站控制器，以及从基站控制器接收数据分组。基站和基站控制器都是称作接入网的网络的组成部分。接入网在多个移动台之间传输数据分组。接入网还可以与接入网以外的其它网络连接，比如企业内网或者因特网，并且在每个移动台和这些外部网络之间传输数据分组。与一个或者多个基站建立了有效业务信道的移动台叫做有效移动台，并且被认为处于业务状态。处于与一个或者多个基站建立有效业务信道连接过程中的移动台被认为处于连接建立状态。开机后且能够从基站接收信号但未处于业务状态或者未处于连接建立状态的移动台，被认为处于空闲状态。
被移动台利用来向基站发送信号的通信链路被称为反向链路。被基站利用来向移动台发送信号的通信链路被称作前向链路。移动台或者用户设备(UE)可以是移动电话，该移动电话包括移动电话手持机，也被称为移动设备(ME)，以及存储模块，比如称作UICC的物理安全集成电路卡或者智能卡，其可移除地或永久地附接于该ME上。在全球移动通信系统(GSM)电话中，所述UICC通常是一个用户识别模块(SIM)。在码分多址(CDMA)电话中，所述UICC通常是一个可移除用户识别模块(RUIM)。
图1是一个说明多播-广播-多媒体系统(MBMS)中的用户设备(UE)2、服务网络4、本地网络6和内容提供商(CP)8之间的通信链路的示例性方框图。该用户设备2可以是一个移动台，该移动台包括移动设备(ME)10和存储模块或者UICC 12。UICC 12可以是附接于移动设备10的一个可移除存储模块，或者是移动设备10的一个永久部分。用户设备2中的UICC 12的物理实现方式对于本发明而言不是关键的。
服务网络4可以由向用户设备2提供订购服务的无线运营商拥有，或者是在用户设备2漫游时向用户设备2提供服务的另一个运营商拥有的被访问网络。服务网络4通常包括无线接入网络(RAN)14和正在服务的通用分组无线服务(GPRS)支持节点(SGSN)16。无线接入网络14也被熟知为基站(BS)、基站收发信机(BTS)，或者接入点(AP)，该无线接入网络将无线电信号发射给用户设备2，以及从用户设备2接收无线电信号。SGSN 16是一个核心网络节点，例如，它可以是公共陆地移动网(PLMN)的一部分。
本地网络6是由向用户设备2提供订购服务的无线运营商拥有的网络，并且取决于用户设备2是否在运营商的服务区域以外漫游，所述本地网络也可以是或可以不是由与服务网络4的运营商相同的运营商拥有的网络。本地网络6通常都包括网关GPRS支持节点(GGSN)18、广播-多播服务中心(BM-SC)20和本地订户服务器(HSS)22。图1中的实线22表示承载路径，在该承载路径上，通过本地网6和服务网络4，将承载信息的信号从内容提供商8传送到移动设备10。图1中的虚线24表示密钥/授权路径，在该密钥/授权路径上，在UICC 12、服务网络4和本地网络6之间传递加密密钥和解密密钥。
内容提供商8可以是第三方内容源，该第三方内容源既不由本地网络运营商拥有，也不由服务网络运营商拥有。本地网络6中的本地订户服务器22可以包括一个数据库，用于保存移动电话订购信息，以及为多播服务收集账单数据。在图1所示的实施例中，本地网络6还包括广播-多播服务中心(BM-SC)20，该广播-多播服务中心(BM-SC)20安排多媒体事件的多播，并且实现所述MBMS的至少一些安全功能。服务网络4是这样一个网络，它通过专用信道将内容发射给单个用户，如果点播所述服务的用户的数量不满足将该服务广播给所述覆盖区域内的所有用户，就通过所述专用信道将内容多播给多个用户，或者如果点播所述服务的用户的数量超过预定阈值，就将所述内容广播给所述覆盖区域内的所有用户。
在一个实施例中，通过几层加密和解密，在多播-广播-多媒体系统中对多媒体事件的内容进行加密和解密，以提供至少一定程度的下述保证，即未授权用户将不能对这些数据进行解密并且不能观看多媒体事件。例如，永久性的用户专用注册密钥(RK)被提供来产生临时密钥(TK)值，并且被提供来认证用户的移动电话中的UICC。所述TK是一个单次使用、用户专用的密钥，其用于加密广播接入密钥(BAK)值。所述TK还被UICC用来对BAK值进行解密。所述BAK是一个中期共享密钥，用于得到多个短期密钥(SK)，并且基于每个用户将该BAK分发给已订购用户的UICC。所述SK是一个频繁改变的共享密钥，用于对内容进行加密和解密。所述SK可以通过使用随机数(SK_RAND)产生，该随机数(SK_RAND)与已加密内容和BAK一起被不受阻碍地发送出去。UICC 12根据BAK和SK_RAND重新产生SK，并且将该SK传递给移动设备10。在2001年8月20日提交的、题目为“Method and Apparatus for Security in a DataProcessing System”的美国专利申请No.09/933,972中描述了用于在多播-广播-多媒体系统中对数据内容进行加密和解密的方案实例，在这里将该文献引入作为参考。在本发明的保护范围之内，还可以实施利用公开密钥或者共享保密密钥进行加密和解密的各种其它实施例。例如，在一个替换实施例中，可以通过使用公开密钥机制(比如RSA或者ElGamal)来实现安全地向UICC传递或提供BAK，对于本领域中的技术人员而言，这是公知的。
图2示出了在多播-广播-多媒体系统中安全注册的一个实施例。在这个实施例中，广播-多播服务中心(BM-SC)20发射一个供给消息，该供给消息是被称作PK的公共陆地移动网(PLMN)密钥以及被称作RK的永久的、用户专用注册密钥的函数。所述PK是一个临时的、本地PLMN专用密钥，用于产生被称作RAK的无线接入网络(RAN)密钥，以及认证UICC12。沿着图2所示的路径26，将所述供给消息从BM-SC 20发射给UICC 12。所述供给消息是以PK和RK为变量的一个函数，可以表示为c1(PK，RK)。在接收到所述供给消息后，UICC 12从所述供给消息中提取出PK，并且存储PK值。通过利用包括但不限于RSA和ElGamal的密钥机制，在本发明的保护范围内还可以提供用于实现将PK安全地递送或提供给UICC的其它实施例。
无线接入网络(RAN)14沿着路径28将用于请求RAK和随机数(RAND)的请求发射给BM-SC 20，与之响应，所述BM-SC 20产生RAK，该RAK是以PK和RAD为变量的函数。BM-SC 20沿着路径30将可以表示为c2(PK，RAND)的RAK发射给RAN 14。所述RAK是一个临时的RAN专用密钥，用于产生临时的用户专用注册密钥(RGK)值，并且使UE 2访问的RAN 14不知道PK。所述RAK还被用于加密MBMS服务识别号(Serv_ID)和用户识别号，比如P-TMSI、IMSI、电子序列号(ESN)、MIN或者在其中实施本发明实施例的系统中使用的任何永久或者临时的用户识别号。在图2和图3所示的实施例中，P-TMSI被用作示例性的用户识别号，对于本领域中的技术人员而言，其是公知的。
RAN可以存储RAK，并且沿着路径32，将RAND广播给RAN的覆盖区域内中包括UE 2在内的所有用户。在接收到RAND后，UE2沿着路径34将RAND和P-TMSI、Serv_ID发送给UICC 12。UICC12产生RAK，该RAM是由BM-SC 20产生的RAK的一个精确复制。在接收到Serv_ID和P-TMSI以后，UICC 12将Serv_ID和P-TMSI串联，以获得一个串连结果，其被表示为[Serv_ID||P-TMSI]，并且基于Serv_ID和P-TMSI来计算一个循环冗余码(CRC)。将CRC附接于[Serv_ID||P-TMSI]之后以产生[Serv_ID||P-TMSI||CRC]。UICC 12随后产生RGK，该RGK是Serv_ID、P-TMSI、CRC和RAK的函数，其被表示为c3([Serv_ID||P-TMSI||CRC]，RAK)。所述RGK是一个临时的用户专用密钥，用于认证注册消息。
在产生了RGK以后，UICC 12沿着路径36将RGK发送给UE 2，UE 2接着沿着路径38将包括RGK的注册/连接请求发送给RAN 14。在接收到注册/连接请求后，RAN 14提取[Serv_ID||P-TMSI]，验证CRC，并且将由P-TMSI标识的用户作为已经发送了有效注册消息来请求多媒体服务的合法用户计数。如果用户发射的所述注册/连接消息未被RAN 14验证，则RAN就将所述用户看作恶意或者非法用户，并且不把该请求作为合法请求计数。
图3说明在多播-广播-多媒体系统中安全注册的另一个实施例。在这个实施例中，广播-多播服务中心(BM-SC)20不发射任何供给消息。取而代之，无线接入网络(RAN)14沿着路径40向BM-SC 20发射用于请求RAK和随机数(RAND)的请求，与之响应，BM-SC 20产生RAK和RAND。RAK是以BAK和RAND为变量的函数，其被表示为c2(BAK，RAND)。所述BAK是同一广播接入密钥，被用作加密方案的一部分，以加密上述数据内容。BM-SC 20沿着路径42将RAND和RAK发射给RAN 14。所述RAK是一个临时的、RAN专用密钥，用于产生临时的、用户专用注册密钥(RGK)值。所述RAK还被用于加密MBMS服务识别号(Serv_ID)和被称作P-TMSI的用户识别号。
RAN可以存储RAK，沿着路径44将RAND广播给RAN覆盖区域内的包括UE 2在内的所有用户。在接收到RAND后，UE 2沿着路径46将RAND以及P-TMSI和Serv_ID发送给UICC 12。UICC 12产生RAK，该RAK是由BM-SC 20产生的RAK的一个精确复制。在接收到Serv_ID和P_TMSI以后，UICC 12将Serv_ID和P_TMSI串联，以获得一个串连结果，其被表示为[Serv_ID||P-TMSI]，并且基于Serv_ID和P-TMSI来计算循环冗余码(CRC)。将CRC附接于[Serv_ID||P-TMSI]之后，以产生[Serv_ID||P-TMSI||CRC]。UICC 12随后产生RGK，该RGK是Serv ID、P-TMSI、CRC和RAK的函数，其被表示为c3([Serv_ID||P-TMSI||CRC]，RAK)。所述RGK是一个临时的用户专用密钥，用于认证注册消息。
在产生了RGK以后，UICC 12沿着路径48将RGK发送给UE 2，UE 2接着沿着路径50将包括RGK的注册/连接请求发送给RAN 14。在接收到注册/连接请求后，RAN 14提取[Serv_ID||P-TMSI]，验证CRC，并且将由P-TMSI标识的用户作为已经发送了有效注册消息来请求多媒体服务的合法用户计数。如果用户发射的所述注册/连接消息未被RAN 14验证，则RAN就将所述用户看作恶意或者非法用户，并且不把该请求作为合法请求计数。
RAN 14从覆盖区域内的多个用户接收到多个注册/连接请求，并且通过验证根据每个用户的Serv_ID和P-TMSI计算出的CRC，确定哪些请求是由合法用户发射的有效请求。RAN可以忽略具有不可验证的CRC的RGK的那些请求。按照这种方式，RAN具有高度可靠的装置来确定请求特定多媒体事件的注册请求中有多少是有效的，如果合法用户的数量不足以广播所述事件，则不会被迫来广播所述事件。
在本发明的保护范围之内，还可以将各种其它特征增加到临时注册消息(RGK)中。例如，可以将系统时间的时间戳增加到RGK中。如果RAN拥有覆盖区域内所有订户的P-TMSI，则RAN 14可以使用从RGK提取的P-TMSI来确定试图注册的用户是否是实际的订户。在典型的GSM系统中，可以在GSM/GPRS，也就是核心网(CN)内的逻辑链路控制(LLC)层上分配P-TMSI。在另一个实施例中，在形成RGK时利用公开密钥，以避免恶意用户的反复攻击。例如，如果每个UICC具有一个用于提供PK或者BAK的私有密钥，那么RGK就可以包括公开密钥或者证书的基准以及具有BAK散列或者PK散列的签名。通过利用诸如基于公开密钥密码术的序列号或者数字签名之类的技术，可以防止或者至少限制恶意用户的反复攻击。
任意一个权利要求中的文字顺序并不意味着处理步骤要按照依照这种顺序的时间顺序或者逻辑顺序进行，除非权利要求中的文字对此进行了具体限定。处理步骤可以按照任意顺序进行互换，而不会偏离本发明的保护范围，只要这种互换不与权利要求的文字相互矛盾且不是不合逻辑的。此外，“第一”、“第二”、“第三”等等这种序数词仅仅表示多个中的不同个体，而不是表示有任何次序或顺序，除非权利要求中的文字对此进行了具体限定。
此外，用于描述不同单元之间关系的“连接”、“与……连接”和名词“连接”这一类词不是暗示这些单元之间必须存在直接的物理连接。例如，两个单元可以是通过一个或者多个其它单元进行物理上、电气上、逻辑上或者任何其它方式的连接，而不会偏离本发明的保护范围。
本领域技术人员将会理解，可以使用各种不同的工艺和技术中的任意技术来表示信息和信号。例如，在整个以上描述中所提及的数据、指令、命令、信息、信号、比特、符号，以及码片可以由电压、电流、电磁波、磁场或粒子，光场或粒子，或者上述的任意组合来表示。
本领域技术人员还会明白，这里结合所公开的实施例描述的各种示例性的逻辑框、模块、电路和算法步骤均可以电子硬件、计算机软件，或二者的结合来实现。为了清楚地示出硬件和软件之间的可交换性，以上对各种示例性的组件、方框、模块、电路和步骤均以其功能性的形式进行总体上的描述。这种功能性是以硬件实现还是以软件实现依赖于特定的应用和整个系统所施加的设计约束。熟练的技术人员能够针对每个特定的应用以多种方式来实现所描述的功能性，但是这种实现的结果不应解释为导致背离本发明的范围。
利用一个通用处理器，数字信号处理器(DSP)，专用集成电路(ASIC)，现场可编程门阵列(FPGA)或者其他可编程的逻辑器件，分立门或者晶体管逻辑，分立硬件组件，或者它们之中的任意组合可以实现或执行结合这里公开的实施例描述的各种示例性的逻辑框图，模块和电路。一个通用处理器可能是一个微处理器，但是在另一种情况中，处理器可能是任何常规的处理器，控制器，微控制器，或者状态机。一个处理器也可能被实现为计算设备的组合，例如，DSP和微处理器的组合，多个微处理器，一个或者更多结合DSP核心的微处理器，或者任何其他此种结构。
结合这里公开的实施例描述的方法或者算法的步骤可直接体现为硬件，由处理器执行的软件模块，或者这二者的组合。一个软件模块可能存在于RAM存储器，闪存，只读(ROM)存储器，可擦写可编程只读(EPROM)存储器，电可擦写可编程只读(EEPROM)存储器，寄存器，硬盘，移动磁盘，紧凑磁盘只读存储器(CD-ROM)，或者本领域熟知的任何其他形式的存储媒质中。一种典型存储媒质与处理器耦合，使得处理器能够从该存储媒质中读信息，且可向该存储媒质写信息。在替换实例中，存储媒质可能与处理器集成。处理器和存储媒质可能存在于一个ASIC中。例如，该ASIC可能存在于一个用户终端中或者作为基站中的分立组件存在。
提供所述公开的实施例的上述描述可使得本领域的技术人员能够实现或者使用本发明。对于本领域的技术人员来说，这些实施例的各种修改是显而易见的，并且这里定义的总体原理也可以在不脱离本发明的范围和主旨的基础上应用于其他实施例。因此，本发明并不限于这里示出的实施例，而是与符合这里公开的原理和新颖特征的最广范围相一致。
