    摘要： Often, for reasons of wireless bandwidth conservation, incomplete messages are provided to wireless messaging devices. Employing cryptography, for confidentiality or authentication purposes, when including a received message that has been incompletely received can lead to lack of context on the receiver's end. By automatically obtaining the entirety of the message to be included, an outgoing message that includes the received message can be processed in a manner that securely and accurately represents the intended outgoing message. Alternatively, a server can assemble a composite message from a new message and an original message and, in cooperation with a wireless messaging device, construct a cryptographic message syntax message.

    摘要： Often, for reasons of wireless bandwidth conservation, incomplete messages are provided to wireless messaging devices. Employing cryptography, for secrecy or authentication purposes, when including a received message that has been incompletely received can lead to lack of context on the receiver's end. By automatically obtaining the entirety of the message to be included, an outgoing message that includes the received message can be processed in a manner that securely and accurately represents the intended outgoing message. Alternatively, a server can assemble a composite message from a new message and an original message and, in cooperation with a wireless messaging device, encrypt and sign the composite message. Conveniently, security considerations are maintained even in view of bandwidth optimization measures.

    摘要翻译： 通常，为了无线带宽保护的原因，向无线消息收发设备提供不完整的消息。 为了保密或认证目的采用加密技术，当包含已经不完整接收到的接收到的消息时，可能导致接收端的缺少上下文。 通过自动获得要包括的消息的整体，可以以安全且准确地表示预期传出消息的方式处理包括接收到的消息的传出消息。 或者，服务器可以组合来自新消息和原始消息的复合消息，并且与无线消息收发设备协作来加密和签署复合消息。 方便的是，即使考虑到带宽优化措施，仍然保持安全考虑。

    摘要： A system and method of forwarding an e-mail from a wireless device is provided. The wireless device receives the e-mail message in portions as needed, the portions having the attachments contained therein. The portions of the e-mail message containing only a subset of attachments associated with the e-mail message in the user mailbox. When a wireless device forwards the e-mail message to one or more recipients a message identifier and an attachment indicator is provided for identifying the number of attachments in the e-mail message to be forwarded. The identified e-mail message is retrieved and the attachments are extracted from the retrieved e-mail message based on the attachment indicator. The e-mail message is forwarded to the one or more recipients and the extracted attachments.

    摘要： A system and method of signing a message to be sent from a first communication device to a destination via a second communication device. The message includes a first portion on the first communication device and a second portion on the second communication device. The method includes receiving at the second communication device the first portion of the message and a first signature for the first portion from the first communication device; combining the first portion and the second portion to form the message; obtaining a second signature for the message; and sending the first signature, the second signature and the message from the second communication device to the destination.
