    Abstract: A novel code signing system, computer readable media, and method are provided. The code signing method includes receiving a code signing request from a requestor in order to gain access to one or more specific application programming interfaces (APIs). A digital signature is provided to the requestor. The digital signature indicates authorization by a code signing authority for code of the requestor to access the one or more specific APIs. In one example, the digital signature is provided by the code signing authority or a delegate thereof. In another example, the code signing request may include one or more of the following: code, an application, a hash of an application, an abridged version of the application, a transformed version of an application, a command, a command argument, and a library.

    Abstract: A system, methods and devices for the secure notification of an identity in a communications network. The methods include sending or receiving a communication including a hash of a certificate of a device to notify or detect the presence of the device in a network. Each certificate is associated with an identity which is excluded from the communication of the hash of the certificate. The received hash is compared to hashes of certificates stored in an electronic device to determine an identity. The identity may represent an electronic device or a user of the electronic device.

    IPC: H04L9/32

    Abstract: Systems and methods for processing encoded messages within a wireless communications system are disclosed. A server within the wireless communications system performs signature verification of an encoded message and provides, together with the message, an indication to the mobile device that the message has been verified. In addition, the server provides supplemental information, such as, for example, a hash of the certificate or certificate chain used to verify the message, to the device, to enable the device to perform additional checks on the certificate, such as, for example, validity checks, trust checks, strength checks, or the like.

    Abstract: In some data communication configurations, data received from a sender may need to be viewed or otherwise processed by more than one entity with a corresponding client. For example, a message sent to a corporate email address may be viewed by either or both a mobile device and a desktop device. For the sender to utilize the strongest algorithm or protocol used by the recipient, it would therefore need to know which algorithms or protocols are supported by both the mobile and desktop mail clients. A system and method are provided to enable the mobile device to know about the capabilities of related mail clients associated with the communication address (e.g. email address) and vice versa such that the intersection of the capabilities (i.e. the strongest algorithm or protocol supported by all parties involved) can be chosen and the messages or data cryptographically processed accordingly.

    Abstract translation: 在一些数据通信配置中，从发送者接收的数据可能需要被具有相应客户端的多个实体查看或以其它方式处理。 例如，发送到公司电子邮件地址的消息可以由移动设备和桌面设备中的一个或两者来查看。 为了使发送方利用接收方使用的最强的算法或协议，因此需要知道移动和桌面邮件客户端支持哪些算法或协议。 提供了一种系统和方法，以使得移动设备能够知道与通信地址（例如，电子邮件地址）相关联的相关邮件客户端的能力，反之亦然，使得能力（即，所有的最强算法或协议 可以选择相关方），并相应地对密码进行处理。

    Abstract: A system and method are provided for pre-processing encrypted and/or signed messages at a host system before the message is transmitted to a wireless mobile communication device. The message is received at the host system from a message sender. There is a determination as to whether any of the message receivers has a corresponding wireless mobile communication device. For each message receiver that has a corresponding wireless mobile communication device, the message is processed so as to modify the message with respect to one or more encryption and/or authentication aspects. The processed message is transmitted to a wireless mobile communication device that corresponds to the first message receiver. The system and method may include post-processing messages sent from a wireless mobile communications device to a host system. Authentication and/or encryption message processing is performed upon the message. The processed message may then be sent through the host system to one or more receivers.
