Description

用户拨号认证方法、 系统和设备 技术领域 本发明主要涉及通信技术领域, 特别地, 涉及一种用户拨号的认证方法和认证 系统, 以及一种用户拨号认证服务器。 背景技术 当用户进行宽带拨号上网时, 传统的认证服务器如远程认证用户拨号 (Remote Authentication Dial In User Service) 服务器根据该用户提供的用户账号信息(比如用 户名 /密码)对其进行认证, 认证通过后, 用户便可访问因特网 (Internet)。
为防止非法用户恶意盗取用户的用户名和密码而对合法用户以及运营商造成 的损失, 在现有技术中, 认证服务器在进行认证时通常是根据预先配置在其内部的 包含合法用户的账号信息和物理端口信息的绑定表对请求认证的用户提供的用户 账号信息和物理端口信息进行匹配核对, 如果二者相一致, 则认证通过; 否则, 认 证失败。
通过以上介绍可以看出, 为实现用户拨号认证, 在现有技术中需要在认证服务 器中维护该包含用户账号信息和物理端口信息的用户信息绑定表。 为使该认证服务 器获取该绑定表, 现有技术通常是通过在工程施工过程中建立并传递用户账号与物 理端口的绑定信息。 具体而言, 运营商在进行工程布线施工时需要制作用户住址信 息与设备物理端口信息的对应表; 当用户开通宽带上网时, 运营商将为该用户分配 账号信息, 根据用户登记的住址信息找到对应的设备物理端口信息, 并将该账户信 息和物理端口信息绑定并配置到认证服务器。 由此, 当用户进行拨号上网时, 认证 服务器便可根据其内部的用户信息绑定表对对该用户进行认证。
不过, 现有技术中, 为实现将用户的账号信息和物理端口信息绑定在认证服务 器中, 需要在工程施工和用户报装等各个阶段进行人工干预, 且流程比较复杂, 因 此容易出错。 发明内容
有鉴于此, 本发明实施例提供一种能解决以上问题的用户拨号认证方法和认证 系统, 以及一种用户拨号认证服务器。 本发明实施例提供的用户拨号认证方法, 其包括: 接收由接入服务器提供的接 入请求报文, 其中所述接入请求报文携带有待认证用户的账号信息和物理端口信 息; 根据所述接入请求报文中的账号信息, 判断所述待认证用户是否为首次请求认 证; 当所述待认证用户为首次请求认证时, 将所述待认证用户的账号信息和物理端 口信息绑定在内部绑定表, 并认证通过; 否则, 根据所述绑定表对所述待认证用户 进行认证。

步骤 S5, 所述认证服务器 140根据其内部绑定表对所述用户进行认证。
具体而言, 在判断出所述用户不是首次拨号的情况下, 所述认证服务器 140根 据其从所述绑定表中查找到的与所述用户对应的表项, 判断所述接入请求报文中承 载的物理端口信息是否与所述表项中的物理端口信息相匹配。 如果相匹配, 所述用 户拨号认证方法转至步骤 S6, 认证通过; 否则, 转至步骤 S7, 认证不通过。
另外, 在步骤 S6中, 在判断出所述用户认证通过时, 所述认证服务器 140可向 所述接入服务器 130返回用于表示所述用户认证通过的接受接入报文。 进一步地, 所述接入服务器 130可将所述接受接入报文转换为对应的认证通过报文, 并通过所 述接入设备 120提供给所述用户设备 110, 以通知所述用户其已经认证通过。 此时便 代表所述用户拨号上网成功, 所述用户便可通过所述用户设备 110进行上网业务, 在网络中进行数据传输, 如图 3所示 (308-310)。
通过以上描述可以看出, 本发明实施例在进行用户拨号认证时, 所述认证服务 器 140总是信任首次拨号的用户为合法用户。 虽然在首次拨号发生非法用户恶意盗 号的概率极低, 但是为了进一步保证网络的安全性, 本发明实施例还进一步提供一 种首次拨号被盗号的防护机制。
具体而言, 当发生首次拨号即被盗号时, 合法用户的账号信息将与非法用户的 物理端口地址绑定在所述认证服务器 140中。 在这种情况下, 合法用户将无法通过 所述认证服务器 140的认证, 其可进行报障处理。 在接收到所述合法用户的报障之 后, 运营商的维护人员可根据所述合法用户提供的故障信息, 通过对应设备的调试 信息获知故障原因, 并进一步修改所述认证服务器 140中的绑定表, 从而解决以上 首次拨号被盗号的问题。
通过以上描述可以看出, 在本发明实施例提供的用户拨号认证方法中, 所述认 证服务器 140在用户首次拨号时总是信任该首次拨号的用户为合法用户, 并根据该 用户的账号信息和物理端口信息建立绑定表, 此后便可直接利用所述绑定表对拨号 的用户进行认证, 整个过程中基本不需要进行人工干预。 由此, 本发明实施例便可 实现在建立绑定表和用户认证时尽可能减少人工干预、 简化流程, 降低出错概率。
另外, 应当理解的是, 虽然在出现首次拨号即被盗号的情况下仍会出现需要维 护人员根据故障信息修改所述认证服务器 140的情况, 不过, 由于首次拨号即被盗 号的几率非常低, 因此相较于现有技术, 从总体上讲本发明实施例提供的用户拨号 认证方法在建立绑定表和用户认证时仍可大大减少人工干预、 降低出错概率。 基于以上实施例提供的用户拨号认证方法, 本发明实施例还进一步提供一种用 户拨号认证系统, 所述用户拨号认证系统可采用图 2所示的网络架构。
具体地, 本发明实施例提供的用户拨号认证系统可包括接入服务器和认证服务 器;
其中, 所述接入服务器, 用于将携带有待认证用户的账号信息和物理端口信息 的接入请求报文提供给所述认证服务器;
所述认证服务器, 用于根据所述接入请求报文中的账号信息, 判断所述待认证 用户是否为首次请求认证, 当所述待认证用户为首次请求认证时从所述接入请求报 文中提取所述账号信息和物理端口信息, 并将所述账号信息和物理端口信息绑定在 内部绑定表, 否则根据所述绑定表对所述待认证用户进行认证。
进一步地, 所述用户拨号认证系统还可以包括:
接入设备, 用于将所述待认证用户的物理端口信息提供给所述接入服务器, 以 使所述接入服务器将所述物理端口信息添加到所述接入请求报文。
进一步地, 所述认证服务器还用于在将首次请求认证的用户的账号信息和物理 端口信息绑定在内部绑定表之后, 还可以向所述接入服务器返回表示所述待认证用 户认证通过的接受接入报文。
通过以上说明可以看出, 本发明实施例提供的用户拨号认证系统同样可实现在 建立绑定表和用户认证时减少人工干预、 简化流程, 降低出错概率。 基于以上实施例提供的用户拨号认证方法和系统, 本发明实施例还提供一种认 证服务器。 请参阅图 4, 所述认证服务器 400包括接收模块 401、 判断模块 402、 认证 模块 403和绑定表 404。
所述接收模块 401, 用于接收由接入服务器提供的接入请求报文, 其中所述接 入请求报文携带有待认证用户的账号信息和物理端口信息;
所述判断模块 402, 用于根据所述接入请求报文中的账号信息, 判断所述待认 证用户是否为首次请求认证;
所述认证模块 403, 用于在所述待认证用户为首次请求认证时从所述接入请求 报文中提取所述账号信息和物理端口信息, 并将所述账号信息和物理端口信息绑定 在内部绑定表 404, 而在所述待认证用户不是首次请求认证时根据所述绑定表 404对 所述待认证用户进行认证。
所述绑定表 404, 用于记录通过认证的用户的账号信息和物理端口信息。
在具体实施例中, 所述绑定表 404可包括多个表项, 每个表项分别对应于一个 通过认证的用户, 且其包括由所述认证模块 403提供的所述通过认证的用户的账号 信息和物理端口信息。
进一步地, 所述认证模块还用于在将首次请求认证的用户的账号信息和物理端 口信息绑定在内部绑定表之后, 向所述接入服务器返回表示所述待认证用户认证通 过的接受接入报文。 通过以上的实施方式的描述, 本领域的技术人员可以清楚地了解到本发明可借 助软件加必需的硬件平台的方式来实现, 当然也可以全部通过硬件来实施。 基于这 样的理解, 本发明的技术方案对背景技术做出贡献的全部或者部分可以以软件产品 的形式体现出来, 该计算机软件产品可以存储在存储介质中, 如 ROM/RAM、 磁碟、 光盘等, 包括若干指令用以使得一台计算机设备 (可以是个人计算机, 服务器, 或 者网络设备等) 执行本发明各个实施例或者实施例的某些部分所述的方法。 以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保护范围并不局限于 此, 任何熟悉本技术领域的技术人员在本发明披露的技术范围内, 可轻易想到的变 化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保护范围应该以权 利要求的保护范围为准。
