Abstract: 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.

Abstract: A system and method for handling e-mail address mismatches between the address contained within a user's certificate or certificate chain, and the account address actually being used is disclosed. In order to resolve address mismatches a canonical or generic domain name or user name may, for example, be used as a lifelong address of a user that is contained in the user's certificate. Upon detection of an address mismatch, the system and method disclosed herein may automatically re-check the certificate or search for a certificate containing the canonical or generic domain name and/or user name to attempt to resolve the mismatch. This mismatch resolution is preferably transparent to the user and occurs automatically. The canonical or generic domain and/or user names that are available to the device may be typically controlled by IT policy that is in place on the system for the device.

Abstract: 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 of the certificates on those certificate servers. If all of the certificates on a certificate server cannot be successfully retrieved using a single search query, due to a search quota on the certificate server being exceeded for example, the search is re-performed through multiple queries, each corresponding to a narrower subsearch. Embodiments described herein enable large amounts of certificates to be automatically searched for and retrieved from certificate servers, thereby minimizing the need for users to manually search for individual certificates.

Abstract: Methods and systems for delivering scalable media content from a server to a client are provided. A server index is provided to a media server for indexing the layers of scalable content in the form of media data groups. The client transmits at least one media request comprising a scalable media presentation identifier, a requested quality identifier and a requested layer identifier. Based on the at least one request, the server identifies the requested media data groups and transmits the requested media data groups to the client. The client receives the requested media data groups, which may be a subset of all available media data groups, and reorders the media data into decoding order for subsequent decoding and playback.

Abstract: 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.
