Abstract: The present invention is in the field of pneumococcal capsular saccharide conjugate vaccines. Specifically, the present invention relates to sized Streptococcus pneumoniae serotype 6A capsular polysaccharides, in particular Streptococcus pneumoniae serotype 6A capsular polysaccharides having the average size (e.g. Mw) of the Streptococcus pneumoniae serotype 6A capsular polysaccharide is between 100-1000 kDa, suitably conjugated to a carrier protein.

Abstract: A method of displaying content items, for example message items in a messaging application or service, is disclosed. The method comprises receiving encrypted content items in a chronological sequence; decrypting the content items; causing display of a display sequence, in order of the chronological sequence, of a respective place holder in place of each of the decrypted content items, and, in response to a user input, causing display of the respective content item in place of one or more of the place holders. Each place holder has an appearance of a scrambled version of the respective content item. The display sequence may be contiguous in received items or sent content items may be interleaved with received content items in the display sequence, in which case sent content items may be displayed with place holders in the same way as received items. A corresponding system and corresponding computer readable medium or media are also disclosed.

Abstract: An apparatus includes an audio-sensor inhibitor configured to inhibit detection of sound by an audio sensor of a communication device, and a secure communication interface coupled to the audio-sensor inhibitor, the secure communication interface being configured to transmit encrypted audio data from the secure communication interface to the communication device, wherein the communication interface generates audio data using a secure-interface audio sensor, and generates the encrypted audio data by encrypting the audio data using a cryptographic module.

Abstract: In an embodiment, a communication device receives a request to establish a media session with a remote endpoint. In response to receiving the request, the communication device exchanges media-session control data with the remote endpoint on behalf of a local endpoint to establish the requested media session between the local endpoint and the remote endpoint. The communication device is communicatively connected to the local endpoint via a Personal Area Network (PAN) communication link. The communication device relays media-session payload data between the local and remote endpoints. The media-session payload data (i) is associated with the media session and (ii) is encrypted based on at least one payload-data cryptographic key that is not accessible to the communication device.

Abstract: Disclosed herein are methods and systems for encrypting communications using a secure element. An embodiment takes the form of a method including the steps of performing a key-exchange procedure with an endpoint via a voice-communication device to obtain a symmetric seed key for a secure voice session with the endpoint; generating first and second symmetric session keys for the secure voice session based on the obtained symmetric seed key; receiving outbound voice packets from the voice-communication device in connection with the secure voice session, each outbound voice packet including a header and an unencrypted payload; using a first symmetric encryption algorithm and the first symmetric session key, followed by a second symmetric encryption algorithm and the second symmetric session key to generate and output twice-encrypted outbound-voice-packet payloads to the voice-communication device for transmission to the endpoint in connection with the secure voice session.

Abstract: Disclosed herein are methods and systems for enabling legal-intercept mode for a targeted secure element.
