摘要:
A system and method for searching and retrieving certificates, which may be used in the processing of encoded messages. In one embodiment, a certificate synchronization application is programmed to perform certificate searches by querying one or more certificate servers for all certificate authority (CA) certificates and cross-certificates on the certificate servers. In another embodiment, all certificates related to an identified certificate are retrieved from the certificate servers automatically by the certificate synchronization application, where the related certificates comprise at least one of one or more CA certificates and one or more cross-certificates. Embodiments of the invention facilitate at least partial automation of the downloading and establishment of certificate chains, thereby minimizing the need for users to manually search for individual certificates.

A system and method of selecting messaging settings on a messaging client are provided. A data store configured to operate in conjunction with the messaging client stores records comprising messaging settings or characteristics for previously received and/or sent messages. The messaging client is configured to send outgoing messages, each of the messages having message characteristics, to determine whether a record for an addressed recipient of an outgoing message exists in the data store, and to select messaging settings to control the message characteristics of the outgoing message based on the record where a record exists.

Preferred embodiments of the invention relate to a method and device for authenticating a user of a computer and a corresponding system using the method and device. The device is a handheld electronic device having accessible thereto a first authentication code of the user. The handheld electronic device requires a second authentication code for enabling use thereof. In order to authenticate the user to the computer, the handheld electronic device is configured to transmit the first authentication code to the computer over a communication link between the computer and the handheld electronic device.
摘要:
A system and method for searching and retrieving certificates, which may be used in the processing of encoded messages. In one broad aspect, certificate identification data that uniquely identifies a certificate associated with a message is generated. The certificate identification data can then be used to determine whether the certificate is stored on a computing device. Only the certificate identification data is needed to facilitate the determination alleviating the need for a user to download the entire message to the computing device in order to make the determination.

Embodiments of the systems and methods described herein facilitate the transmitting, receiving, and processing of encoded messages wherein the header fields in the message header are protected. In one embodiment, the contents of the header fields to be protected are inserted into the message body as one or more additional lines of text, for example, prior to encoding and transmitting the message to a message recipient. Upon receipt of the message, the message recipient processes the encoded message such that the contents of the protected header fields can be extracted from the message body. Accordingly, by inserting the contents of the header fields to be protected into the message body, the header fields may be protected using existing standards and protocols for facilitating secure message communication.

Systems and methods for operation upon a data processing device for handling messages with different levels of security, are provided herein. A method for operation upon a data processing device for handling messages with different levels of security includes examining an attribute of a message received over a network in order to determine a security-related level associated with the message, generating a visual indication for display to a device user that is indicative of the determined security-related level, wherein the generated visual indication is applied to a displayed portion of text associated with the message, and changing the visual indication when the message viewed.

Systems and methods for displaying messages to a user, the messages having different levels of security, are provided herein. One method of displaying to a user messages having different levels of security includes receiving a message over a network includes examining an attribute of the message to determine a security-related level associated with the message. A visual indication for display to a device user is generated by the device. Such visual indication is indicative of the determined security-related level, and is configured to be visible during scrolling through a majority of the message text.
摘要:
A system and method for generating a security indicator on a display of a computing device (e.g. a mobile device), to indicate when the computing device is in a secure state while locked. A determination is made (e.g. by a data protection system) as to whether at least some of the secure data stored on the computing device can be decrypted by any applications on the computing device, while the computing device is in the locked state. An icon or other identifier can be displayed to indicate that the secure state has been attained. In one embodiment, the secure state is considered to have been attained, if it is determined that all tickets that have been issued to applications on the computing device while the computing device was unlocked have been released, and any decrypted encryption keys that may be used to decrypt the secure data have been deleted.

A method and system for Certificate management and transfer between messaging clients are disclosed. When communications are established between a first messaging client and a second messaging client, one or more Certificates stored on the first messaging client may be selected and transferred to the second messaging client. Messaging clients may thereby share Certificates. Certificate management functions such as Certificate deletions, Certificate updates and Certificate status checks may also be provided.
