    • Described is a technology comprising a system in which two distrusting parties can submit sets of encrypted keywords using two independent secret keys to a third party who can decide, using only public keys, if the underlying cleartext message of a cryptogram produced by one distrusting party matches that of a cryptogram produced by the other. The third party (e.g., a server) uses generator information corresponding to a generator of an elliptic curve group to determine whether the sets of encrypted keywords match each other. Various ways to provide the generator information based upon the generator are described. Also described is the use of one-ray randomization and two-way randomization as part of the system to protect against dictionary attacks.
    • 描述了一种技术,其包括一种系统,其中两个不信任方可以使用两个独立的秘密密钥向第三方提交一组加密的关键字,该第三方可以仅使用公钥来决定如果由一个不信任方产生的密码的底层明文消息匹配 另一个密码产生的密码。 第三方(例如,服务器)使用与椭圆曲线组的生成器相对应的生成器信息来确定加密关键字的集合是否彼此匹配。 描述了基于发电机提供发电机信息的各种方式。 还描述了使用单线随机化和双向随机化作为系统的一部分来防止字典攻击。

    • Native IPv6 capabilities are provided to an IPv4 network node, device, or endpoint using a hardware interface that supports network communication under a Direct Access model. The Direct Access model supports IPv6 communication with IPsec and enforces Network Access Protection (“NAP”) health requirement policies for endpoints that are network clients. A Direct Access-ready server is enabled using a hardware interface that implements IPv4 to IPv6 translation and optionally IPsec termination capability. A Direct Access-ready client is enabled using a hardware interface that implements IPv4 to IPv6 translation, IPsec termination capability, and which optionally provides NAP (Network Access Protection) capabilities for Direct Access-ready clients that are configured as mobile information appliances. The hardware interface may be implemented as a network interface card (“NIC”) or as a chipset.
    • 本地IPv6功能使用支持直接访问模式下的网络通信的硬件接口提供给IPv4网络节点,设备或端点。 直接访问模式支持与IPsec的IPv6通信,并对作为网络客户端的端点实施网络访问保护(“NAP”)健康要求策略。 使用实现IPv4到IPv6转换和可选的IPsec终止功能的硬件接口启用直接访问就绪服务器。 使用实现IPv4到IPv6转换,IPsec终止功能的硬件接口启用直接访问就绪客户端,并且可选地为配置为移动信息设备的直接访问就绪客户端提供NAP(网络访问保护)功能。 硬件接口可以实现为网络接口卡(“NIC”)或芯片组。
