摘要： Cryptographic systems and methods are provided in which authentication operations, digital signature operations, and encryption operations may be performed. Authentication operations may be performed using authentication information. The authentication information may be constructed using a symmetric authentication key or a public/private pair of authentication keys. Users may digitally sign data using private signing keys. Corresponding public signing keys may be used to verify user signatures. Identity-based-encryption (IBE) arrangements may be used for encrypting messages using the identity of a recipient. IBE-encrypted messages may be decrypted using appropriate IBE private keys. A smart card, universal serial bus key, or other security device having a tamper-proof enclosure may use the authentication information to obtain secret key information. Information such as IBE private key information, private signature key information, and authentication information may be stored in the tamper-proof enclosure.

摘要： Secure messages may be sent between senders and recipients using symmetric message keys. The symmetric message keys may be derived from a master key using a key generator at an organization. A gateway may encrypt outgoing message using the derived keys. Senders in the organization can send messages to recipients who are customers of the organization. The recipients can authenticate to a decryption server in the organization using preestablished credentials. The recipients can be provided with copies of the derived keys for decrypting the encrypted messages. A hierarchical architecture may be used in which a super master key generator at the organization derives master keys for delegated key generators in different units of the organization. An organization may have a policy server that generates non-customer symmetric message keys. The non-customer symmetric message keys may be used to encrypt messages sent by a non-customer sender to a recipient at the organization.
摘要翻译：可以使用对称消息密钥在发送方和收件人之间发送安全消息。对称消息密钥可以使用组织中的密钥生成器从主密钥导出。网关可以使用导出的密钥来加密传出的消息。组织中的发件人可以向作为组织客户的收件人发送消息。收件人可以使用预先建立的凭据对组织中的解密服务器进行身份验证。可以向收件人提供用于解密加密消息的导出密钥的副本。可以使用分层结构，其中组织中的超级主密钥生成器为组织的不同单元中的委托密钥生成器导出主密钥。组织可以具有生成非客户对称消息密钥的策略服务器。非客户对称消息密钥可以用于将由非客户发送者发送的消息加密到组织的接收者。

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： 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.
摘要翻译：提供了安全消息传递的系统和方法。发送者可以加密内容，并通过通信网络将加密的内容发送给接收者。可以使用远程解密服务为接收者解密加密内容。加密的消息内容可以被放置成标记语言形式。加密内容可以作为隐藏表单元素合并到表单中。收集凭证信息（如用户名和密码信息）的表单元素也可以并入表单中。在接收方，收件人可以使用该表单向远程解密服务提供接收者凭证信息。收件人还可以使用表格将加密的内容从表单上传到解密服务。解密服务可以通过通信网络向接收者提供对已上传内容的解密版本的访问。

摘要： Systems and methods for managing email are provided. Some of the email may be encrypted using identity-based-encryption (IBE) techniques. When an incoming IBE-encrypted message for a recipient in an organization is received by a gateway at the organization, the gateway may request an IBE private key from an IBE private key generator. The IBE private key generator may generate the requested IBE private key for the gateway. The gateway may use an IBE decryption engine to decrypt the incoming message. The decrypted message can be scanned for viruses and spam and delivered to the recipient. Outgoing email messages can also be processed. If indicated by message attributes or information provided by a message sender, an outgoing message can be encrypted using an IBE encryption engine and the IBE public key of a desired recipient.
摘要翻译：提供用于管理电子邮件的系统和方法。一些电子邮件可以使用基于身份的加密（IBE）技术进行加密。当组织中的网关接收到用于组织中的接收者的传入IBE加密消息时，网关可以从IBE私钥生成器请求IBE私钥。 IBE私钥生成器可以为网关生成请求的IBE私钥。网关可以使用IBE解密引擎来解密传入的消息。解密的消息可以扫描病毒和垃圾邮件并传送给收件人。也可以处理传出的电子邮件。如果由消息属性或由消息发送者提供的信息指示，可以使用IBE加密引擎和所需接收者的IBE公钥来加密输出消息。
