    • A system and method that facilitates the authentication of streamed data received at a device, where authentication information is not distributed over the data stream. One embodiment of a method of authenticating data comprises the steps of: receiving, at the device, data in a plurality of packets transmitted by a data server; submitting a request for a server-computed authentication value to a data authentication server, wherein the data authentication server is adapted to compute the server-computed authentication value based on a subset of the data transmitted by the data server; receiving, at the device, the server-computed authentication value from the data authentication server in response to the request; computing a device-computed authentication value based on a subset of the data received at the device corresponding to the subset of the data transmitted by the data server; and determining if the subset of the data received at the device is authentic by comparing the server-computed and device-computed authentication values.
    • 一种有助于在设备处接收的流数据的认证的系统和方法,其中认证信息不分布在数据流上。 验证数据的方法的一个实施例包括以下步骤:在设备处接收由数据服务器发送的多个分组中的数据; 向数据认证服务器提交服务器计算的认证值的请求,其中所述数据认证服务器适于基于由所述数据服务器发送的数据的子集来计算所述服务器计算的认证值; 在所述设备处,响应于所述请求从所述数据认证服务器接收所述服务器计算的认证值; 基于在与由数据服务器发送的数据的子集相对应的在设备处接收到的数据的子集来计算设备计算的认证值; 以及通过比较服务器计算的和设备计算的认证值来确定在设备处接收到的数据的子集是否是真实的。

    • Embodiments of the systems, devices, and methods described herein generally facilitate the secure transmittal of security parameters. In accordance with at least one embodiment, a representation of first data comprising a password is generated (705) at the first computing device as an image or audio signal (710). The image or audio signal is transmitted (715) from the first computing device to the second computing device. The password is determined from the image or audio signal at the second computing device (725). A key exchange (730,740) is performed between the first computing device and the second computing device wherein a key (736,748) is derived at each of the first and second computing devices. In at least one embodiment, one or more security parameters (e.g. one or more public keys) are exchanged (744,750) between the first and second computing devices, and techniques for securing the exchange of security parameters or authenticating exchanged security parameters are generally disclosed herein.

    • A system and method for processing attachments to messages sent to a mobile device is described herein. Embodiments described herein apply to encrypted messages comprising multiple message parts, in which different encryption keys (e.g. session keys) have been used to encrypt the different message parts. In at least one example embodiment, the encrypted session keys for every message content part comprising an attachment is received at the mobile device. In one embodiment, all of the encrypted session keys are stored together in a main message header. The mobile device may then decrypt the encrypted session key associated with a user requested attachment, and transmits the decrypted session key to one or more remote servers in an attachment request for use in decrypting the requested attachment. Data associated with the requested attachment, in decrypted form, is returned to the mobile device.
    • 一种用于处理附件发送到移动设备的消息的系统和方法中描述。 详见实施例适用于包括其中不同的加密密钥(例如,会话密钥)的多个消息部分已被用于不同的消息部分进行加密的加密消息。 在至少一个示例实施例,在移动设备处接收针对每个消息内容部分包括附件的经加密的会话密钥。 在一个实施例中,所有的加密的会话密钥被一起存储在主消息报头。 然后移动设备可以解密用用户请求的附件相关的经加密的会话密钥,并且将解密的会话密钥到一个或多个远程服务器中的附着请求用于解密所请求的附件。 在解密形式的请求的附件相关联的数据,则返回到该移动设备。
