    摘要： Single-use character combinations are a secure mechanism for user authentication. Such “one-time passwords” (OTPs) can be generated by a mobile device to which the user otherwise maintains easy access. A key exchange, such as in accordance with the Diffie-Hellman algorithm, can provide both the mobile device and a server with a shared secret from which the OTPs can be generated. The shared secret can be derived from parameters posted on the server and updated periodically, and the mobile device can obtain such parameters from the server before generating an OTP. Such parameters can also specify the type of OTP mechanism to be utilized. A second site can, independently, establish an OTP mechanism with the mobile device. For efficiency, the first server can provide an identity token which provides the mobile device's public key in a trusted manner, enabling more efficient generation of the shared secret with the second server.

    摘要翻译： 一次性字符组合是用户认证的安全机制。 这种“一次性密码”（OTP）可以由用户另外保持容易访问的移动设备生成。 密钥交换，例如根据Diffie-Hellman算法，可以向移动设备和服务器提供可以从其生成OTP的共享秘密。 共享密钥可以从服务器上发布的参数导出，并定期更新，移动设备可以在生成OTP之前从服务器获取这些参数。 这样的参数也可以指定要使用的OTP机制的类型。 第二个站点可以独立地使用移动设备建立OTP机制。 为了提高效率，第一台服务器可以提供一种以令人信服的方式提供移动设备公钥的身份令牌，从而能够更有效地生成第二台服务器的共享密钥。

    摘要： A system and method for automatically determining if a computer user is a human or an automated script. Human interactive proofs (HIPs) are currently used to deter automated registration for web services by automated computer scripts. Unfortunately, HIPs entail multiple steps (request service, receive challenge, respond to challenge) that can be burdensome. The system and method of the invention in one embodiment provides a “black-box” to potential users consisting of a challenge generator and a secret key. The challenge is generated for the user and the response can be provided as part of the service request, eliminating the need for a separate challenge from a service provider and response to the challenge.

    摘要： A hierarchical identity based cryptographic system (“HIBC”) is integrated with the domain name system (“DNS”). A private key is assigned to each of the top level domain name authorities responsible for assigning the top level domain names (e.g., net, .com, etc.). The private key is generated according to an HIBC system, wherein the corresponding public key is based on the identity of the particular domain authority. When user requests a domain name from one of the top level domain name authorities, the user is issued a private key that is generated by the top level domain authority using its private key and the identity of the user according to the particular HIBC system implemented. The user's corresponding public key can be derived from the identity of the user and the public key of the top level domain name authority. Similarly, when the user adds servers and accounts to the users domain, the user can generate private keys for the servers and accounts using the users private key according to the particular HIBC system. Later, emails originating from the users domain can be authenticated by recipients using the public key associated with the top level domain name authority.

    摘要： Disclosed are systems and methods that facilitate securing communication channels used in a challenge-response system to mitigate spammer intrusion or deception. The systems and methods make use of unique IDs that can be added to outbound messages originating from a sender, a recipient, and a third-party server. The IDs can be correlated according to the relevant parties. Thus, for example, a sender can add a signed ID to an outgoing message. A challenge sent back to the sender for that particular message can echo the same ID or a new ID derived from the original ID to allow a sender to verify that the challenge corresponds to an actual message. The IDs can include cookies as well to facilitate correlation of messages and to facilitate the retrieval of messages once a sender is determined to be legitimate.

    摘要： Manifest-based trusted agent management in a trusted operating system environment includes receiving a request to execute a process is received and setting up a virtual memory space for the process. Additionally, a manifest corresponding to the process is accessed, and which of a plurality of binaries can be executed in the virtual memory space is limited based on indicators, of the binaries, that are included in the manifest.

    摘要： An exclusive encryption system is established using multiple computing devices. The exclusive encryption system allows for the exclusion of certain plaintext (e.g., by one of the computing devices) and ciphertext (e.g., by another of the computing devices) while at the same time maintaining the privacy created by the encryption (e.g., so the other computing device cannot see the plaintext). The exclusive encryption system may be implemented as part of a serverless distributed file system with directory entries (e.g., file names or folder names) being the plaintext, or alternatively as part of other systems.
