先对本文所涉及的一些概念进行说明。
SIM是Subscriber Identity Module的缩写,中文为身份认证模块,即通常意义讲的 SIM 卡,它是通用集成电路卡的一种,作用是通过此模块来认证运营商网络的合法用户。
UICC是Universal Integrated Circuit Card的缩写,是通用集成电路卡的意思,例如上面提及的通信 SIM 卡、金融银行卡和公交卡等都是通用集成电路卡。
eUICC来源于embedded UICC的进一步缩写,指可插拔的或者嵌入式的通用集成电路卡,通常指 eSIM 卡,这种卡支持以一种安全的方式对 Profile 进行远程和本地的管理。
EID是eUICC ID的进一步缩写,指 eUICC 卡的唯一标识。
Profile的英文解释为:a combination of data and applications to be provisioned on an SIM or eUICC for the purpose of providing services;Profile是指为了提供某些服务而能够被安装和存储在普通SIM卡或eUICC卡里面的相应数据和应用。
LPA,是Local Profile Assistant的缩写,是本地Profile助手的意思,其功能包括辅助Profile下载、Profile 管理(包括Profile启用、Profile关闭、Profile删除、Profile信息查询)和提供Profile管理界面。
SM-DP+是 Subscription Manager Data Preparation Plus的缩写,中文为订阅管理数据准备服务器,主要功能有准备 Profile,安全的加密、存储和分配 Profile 到指定的 EID。通过绑定一个加密的 Profile 安全的通过 LPA 下发到 eUICC 上。
MNO是Mobile Network Operator的缩写,是移动运营商的意思,移动运营商例如可以是中国移动、中国联通和海外各个国家的运营商等,用于给用户提供移动网络服务,包括语音、短信和数据等。
GSMA即GSM Association,是指国际电信联盟,主要参与者有运营商、卡商、终端设备厂商等,负责整体涉及到通信、Profile、核心网等领域的整体技术标准规范和统一协调。
HSM是Hardware Security Module的缩写,指硬件安全模块,是一种用于保障和管理强认证系统所使用的数字密钥,并同时提供相关密码学操作的计算机硬件设备。硬件安全模块一般通过扩展卡或外部设备的形式直接连接到电脑或网络服务器。
KMS是Key Management System的缩写,是指密钥管理系统。
对称密钥,英文为Symmetric Key。对称密钥加密又叫专用密钥加密或共享密钥加密,即发送和接收数据的双方必使用相同的密钥对明文进行加密和解密运算。对称密钥加密算法主要包括:DES、3DES、AES、RC5、RC6等。
非对称密码学,英文为Asymmetric Cryptography,是密码学的一种算法,它需要两个密钥,一个是公开密钥(Public Key),另一个是私有密钥(Private Key);公钥用作加密,私钥则用作解密。使用公钥把明文加密后所得的密文,只能用相对应的私钥才能解密并得到原本的明文,最初用来加密的公钥不能用作解密。由于加密和解密需要两个不同的密钥,故被称为非对称加密;不同于加密和解密都使用同一个密钥的对称加密。公钥可以公开,可任意向外发布;私钥不可以公开,必须由用户自行严格秘密保管,绝不透过任何途径向任何人提供,也不会透露给被信任的要通信的另一方。基于公开密钥加密的特性,它还能提供数字签名(Digital Signature)的功能,使电子文件可以得到如同在纸本文件上亲笔签署的效果。
SFTP即SSH File Transfer Protocol,也称Secure File Transfer Protocol,中文为安全文件传送协议,这是一数据流连线,提供文件访问、传输和管理功能的网络传输协议。
解释完上面的概念后,下面对本发明进行说明。
当前SIM卡产线一般是采用烧录的方式将Profile数据写入SIM卡中;而运营商将Profile数据传递给SIM卡厂商的方式则不一,使用的存储介质也不尽相同,例如采用U盘或CD,亦或采用电子邮件或SFTP等方式传输,SIM卡厂商接收数据后录入到SIM卡产线的PC数据库内。
现有技术有诸多缺点。例如物理介质传递耗时较长且过程中容易丢失,再例如Profile数据通过线下或电子传输后的接收需要人工介入才能完成,效率低下,再例如,保护Profile数据的密钥存在被泄露的可能。
本文描述了一种Profile数据的安全传输方案,用于解决运营商在码号传输的开始阶段安全地传递给eSIM的订阅管理数据准备服务器(SM-DP+),以保证后续码号分发在安全上的完整性。
请参照图1,为本发明中各方交互的一个示意图。
密钥管理系统KMS主要提供两部分的功能,一是接入硬件安全模块HSM,二是管理所有密钥和证书。
GSMA Consumer eSIM方案定义了SM-DP+与运营商订购Profile的ES2+接口,以及SM-DP+与eUICC下载Profile的ES9+接口,但并未定义SM-DP+与运营商在开始之初如何传递码号Profile,并且以一种安全高效的方式。本文对SM-DP+进行了改进,改进后的SM-DP+补充完善了这一部分功能,一方面保证安全接收运营商传递过来的Profile数据,另一方面负责使用KMS的加密功能将敏感数据保存,以便后续维护和使用。
请参照图2,下面不妨以运营商安全传输码号(Profile)至SM-DP+为例,说明本发明是如何实施的。
(1)密钥管理系统KMS发起密钥典礼,即密钥的创建流程,为一运营商MNO创建一对密钥对(Key pair)。密钥对包括公钥(mPK,MNO Public Key)和私钥(mSK,MNO Private Key)。
可以理解地,此过程需要密钥经理、密钥管理员多人参与,分别以自身账号与口令登陆KMS,各人员的操作细节在此不表。密钥典礼需要多位安全人员参与,在技术的基础上实现制度方面的安全制衡,可以保证密钥在源头上不会被窃取与泄露。
(2)密钥管理系统KMS将密钥对保存至硬件安全模块HSM。至此,密钥本身的内容已无法被外界破获。
(3)订阅管理数据准备服务器SM-DP+根据运营商MNO的标识向密钥管理系统KMS发送请求密钥的消息。
(4)密钥管理系统KMS向硬件安全模块HSM发起请求相应密钥的消息;
(5)硬件安全模块HSM向密钥管理系统KMS返回密钥对中的公钥(mPK,MNO Public Key)及对应的密钥ID(KID,Key Identity);
(6)密钥管理系统KMS向订阅管理数据准备服务器SM-DP+返回所接收到的公钥mPK及对应的密钥ID,密钥典礼完成,后续的码号数据(Profile)添加动作不需要重复密钥典礼。
(7)运营商MNO向订阅管理数据准备服务器SM-DP+发送请求加密Profile数据的公钥mPK。
(8)订阅管理数据准备服务器SM-DP+根据运营商MNO标识,选择相应的公钥mPK并向运营商MNO返回。
(9)运营商MNO生成一个基于会话(Session)的对称密钥(AES Key),并使用该对称密钥将Profile数据的敏感部分加密,以及使用所接收到的公钥mPK将对称密钥AES Key加密处理,然后将加密后的Profile数据和加密后的对称密钥AES Key发送给订阅管理数据准备服务器SM-DP+。
(10)订阅管理数据准备服务器SM-DP+向运营商MNO返回Profile数据添加成功的消息。
(11)订阅管理数据准备服务器SM-DP+将Profile数据中的非敏感的部分传输至密钥管理系统KMS。
(12)订阅管理数据准备服务器SM-DP+将Profile数据中被加密的敏感部分和携带着相应公钥mPK的密钥ID传输至密钥管理系统KMS。
(13)密钥管理系统KMS根据密钥ID从硬件安全模块HSM中获取相应的受保护的私钥(mSK,MNO Private Key)——可以理解地,由于私钥存放于硬件安全模块HSM,因此私钥是受保护的;使用该私钥mSK对加密后的对称密钥AES Key进行解密,再使用解密后的对称密钥AES Key对Profile数据中被加密的敏感部分进行解密。
由于Profile数据中的非敏感的部分和敏感的部分可能是交替出现的,因此上述步骤(11)这一步骤,与步骤(12)和(13)这两个步骤所构成的流程,实际是交替循环执行,以使得密钥管理系统KMS中最终有Profile数据中所有的非敏感的部分,和所有的被解密后的敏感部分。
(14)订阅管理数据准备服务器SM-DP+向密钥管理系统KMS发出将Profile数据进行拼接的命令。
(15)响应于将Profile数据进行拼接的命令,密钥管理系统KMS将Profile数据中的非敏感的部分和Profile数据中被解密后的敏感部分合成一个完整的Profile数据包(Package)。
(16)订阅管理数据准备服务器SM-DP+向密钥管理系统KMS发出使用随机密钥(Random Key)将Profile数据包进行加密的命令;
(17)响应于使用随机密钥Random Key将Profile数据包进行加密的命令,密钥管理系统KMS使用随机密钥Random Key将整个的Profile数据包进行加密,并将随机密钥Random Key保存至硬件安全模块HSM。
(18)密钥管理系统KMS将加密后的Profile数据包和随机密钥ID发送至订阅管理数据准备服务器SM-DP+,至此完成Profile的安全传输。
请参照图3,下面不妨以终端例如物联网终端下载标准GSMA Profile的流程为例,说明本发明是如何实施的。
Profile能够被安装和存储在终端的eUICC卡里面,具体地,可以通过终端的LPA来辅助Profile下载、Profile 管理(包括Profile启用、Profile关闭、Profile删除、Profile信息查询)和提供Profile管理界面。
(1)终端向订阅管理数据准备服务器SM-DP+发起InitiateAuthentication请求。
(2)订阅管理数据准备服务器SM-DP+向终端返回InitiateAuthOk;
(3)终端向订阅管理数据准备服务器SM-DP+发起AuthenticateClient请求;
(4)订阅管理数据准备服务器SM-DP+向终端返回AuthClientOk;
(5)终端向订阅管理数据准备服务器SM-DP+请求GetBoundProfilePackage;
(6)订阅管理数据准备服务器SM-DP+在与终端的上述交互步骤(即InitiateAuthentication请求到InitiateAuthOk,AuthenticateClient请求到AuthClientOk这两个交互过程)中已获取到会话密钥Session Keys,因此订阅管理数据准备服务器SM-DP+将会话密钥Session Keys、加密后的Profile数据包或者说受保护的Profile数据包(PPP,Protected Profile Package),和随机密钥ID传输给密钥管理系统KMS。
(7)密钥管理系统KMS根据随机密钥ID从硬件安全模块HSM中获取相应的受保护的随机密钥Random Key——可以理解地,由于随机密钥Random Key存放于硬件安全模块HSM,因此随机密钥Random Key是受保护的;并使用该随机密钥Random Key对PPP进行解密,得到解密后的Profile数据包,或者说未受保护的Profile数据包(UPP,Unprotected Profile Package)
(8)密钥管理系统KMS使用(6)中所提及的会话密钥Session Keys循环对UPP使用SCP03t算法进行加密。
(9)密钥管理系统KMS将加密并绑定的Profile数据包(BPP,Bound Profile Package)传输至订阅管理数据准备服务器SM-DP+。
(10)订阅管理数据准备服务器SM-DP+向终端返回GetBppOk。
上述流程中,步骤(1)、(2)、(3)、(4)、(5)、(9)、(10)都是GSMA所制定的标准eUICC Consumer eSIM方案的Profile下载流程步骤。
