摘要： A URL verification service is provided that is used to evaluate the trustworthiness of universal resource locators (URLs). As a user browses the world wide web, the URL for a web page to which the user is browsing is captured by the service. The URL has a second level domain corresponding to a web site. The URL verification service identifies a proposed brand that should be associated with the URL if the URL is trustworthy. The proposed brand and the second level domain are used as database queries to query a database such as a search engine database. The results of the database query are processed to determine whether the URL is legitimately associated with the URL. To ensure that the proposed brand is identified accurately, the URL verification service gathers brand information using web page content, secure sockets layer certificate content, or other web site attributes.

摘要： Personalization images are included in email messages to combat phishing attacks in which an attacker attempts to trick a user into divulging sensitive information over the Internet. When a recipient of an email message receives a message, the recipient can visually inspect the personalization image in the message. If the personalization image is missing or if the personalization image is not valid, the email recipient is alerted to the possibility of a phishing attack. Email message content may be encrypted. A gateway associated with an email message sender may be used to perform encryption operations on the message content. The gateway may create an html version of the email by placing the encrypted message content in an html wrapper. An image reference corresponding to the personalization image may be embedded in the html version of the message.
摘要翻译： 个性化图像包含在电子邮件消息中，以防止攻击者试图欺骗用户通过Internet泄露敏感信息的网络钓鱼攻击。 当电子邮件消息的收件人收到消息时，收件人可以直观地检查消息中的个性化图像。 如果个性化图像丢失或个人化图像无效，电子邮件收件人将被警告可能发生网络钓鱼攻击。 电子邮件内容可能被加密。 与电子邮件消息发送者相关联的网关可以用于对消息内容执行加密操作。 网关可以通过将加密的消息内容放置在html包装器中来创建电子邮件的html版本。 对应于个性化图像的图像引用可以嵌入在消息的html版本中。

摘要： A system is provided that uses cryptographic techniques to support secure messaging between senders and recipients. A sender may encrypt a message for a recipient using the recipient's public key. The sender may send the encrypted message to the message address of a given recipient. A server may be used to decrypt the encrypted message for the recipient, so that the recipient need not install a decryption engine on the recipient's equipment.

摘要： Systems and methods for secure messaging are provided. A sender may encrypt content and send the encrypted content to a recipient over a communications network. The encrypted content may be decrypted for the recipient using a remote decryption service. Encrypted message content may be placed into a markup language form. Encrypted content may be incorporated into the form as a hidden form element. Form elements for collecting recipient credential information such as username and password information may also be incorporated into the form. At the recipient, the recipient may use the form to provide recipient credential information to the remote decryption service. The recipient may also use the form to upload the encrypted content from the form to the decryption service. The decryption service may provide the recipient with access to a decrypted version of the uploaded content over the communications network.

摘要： A system is provided that uses identity-based encryption to support secure communications. Messages from a sender to a receiver may be encrypted using the receiver's identity and public parameters that have been generated by a private key generator associated with the receiver. The private key generator associated with the receiver generates a private key for the receiver. The encrypted message may be decrypted by the receiver using the receiver's private key. The system may have multiple private key generators, each with a separate set of public parameters. Directory services may be used to provide a sender that is associated with one private key generator with appropriate public parameters to use when encrypting messages for a receiver that is associated with a different private key generator. A certification authority may be used to sign directory entries for the directory service. A clearinghouse may be used to avoid duplicative directory entries.

摘要： A system is provided that uses identity-based encryption to support secure communications between senders and recipients over a communications network. Private key generators are used to provide public parameter information. Senders encrypt messages for recipients using public keys based on recipient identities and using the public parameter information as inputs to an identity-based encryption algorithm. Recipients use private keys to decrypt the messages. There may be multiple private key generators in the system and a given recipient may have multiple private keys. Senders can include private key identifying information in the messages they send to recipients. The private key identifying information may be used by the recipients to determine which of their private keys to use in decrypting a message. Recipients may obtain the correct private key to use to decrypt a message from a local database of private keys or from an appropriate private key server.

摘要： A system is provided that uses identity-based encryption (IBE) to support secure communications. Messages from a sender may be encrypted using an IBE public key and IBE public parameter information associated with a recipient. The recipient may decrypt IBE-encrypted messages from the sender using an IBE private key. A host having a service name may be used to store the IBE public parameter information. The sender may use a service name generation rule to generate the service name based on the IBE public key of the recipient. The sender may use the service name to obtain the IBE public parameter information from the host.
