Abstract: Exemplary embodiments relate to techniques for end-to-end encrypted interactive messaging between users of a communication system. For example, the interactive messaging may be based on a message template. An end-to-end encrypted message may be sent to a recipient. The encrypted message may contain at least a template identifier associated with the message template and one or more dynamic parameters. The receiving device may decrypt the message and hydrate the message template with the one or more dynamic parameters.

Abstract: A network function virtualization system, comprises a request receiving unit that receives a request to a certificate of at least one of data exchanging parties; a private key generator that generates a first private key information using a second private key information stored in a hardware-based isolated secure execution environment, in response to the request; a public key extractor that extracts a public key information of the first private key information; a public key information storage unit that stores the public key information; and a verifying unit that is accessible from the request receiving unit and verifies the certificate using the public key information corresponding to the certificate.

Abstract: To enable security enhancement in the case of employing beamforming. A first apparatus according to the present invention includes: an information obtaining unit configured to obtain information related to beam selection; and a key generating unit configured to generate a security key for radio communication between a base station and a terminal apparatus based on the information related to the beam selection.

Abstract: In one embodiment, a system for providing a distal embolic protection including a distal embolic protection flow catheter configured for insertion into an artery, the catheter comprising one or more outlet apertures configured to eject fluid into the artery to drive embolic particles within the artery in a desired direction

Abstract: A pharmaceutical composition comprising a cyclo-dipeptide and use thereof for treatment of a wound. The cyclo-dipep-tide can be Cyclo-His-Pro and the pharmaceutical composition can suitable for topical application to a wound. The compositions can be used to treat a wound, reduce tissue damage in a wound, prevent and/or reduce oxidative damage in a wound, and/or reduce the amount of heme in a wound.

Abstract: In order for supporting separate ciphering at an MeNB (20) and an SeNB (30), the MeNB (20) derives separate first and second keys (KUPenc-M, KUPenc-S) from a third key (KeNB). The first key (KUPenc-M) is used for confidentially protecting first traffic transmitted over U-Plane between the MeNB (20) and a UE (10). The first key (KUPenc-M) may be the same as current KUPenc or a new key. The second key (KUPenc-S) is used for confidentially protecting second traffic transmitted over the U-Plane between the UE (10) and the SeNB (30). The MeNB (20) sends the second key (KUPenc-S) to the SeNB (30). The UE (10) negotiates with the MeNB (20), and derives the second key (KUPenc-S) based on a result of the negotiation.

Abstract: A call relay system includes: an outgoing call terminal; an incoming call terminal; and a call relay device which relays a call from the outgoing call terminal to the incoming call terminal.

Abstract: To achieve a secure and fast handover in a distributed mobile communication environment (10), the control functionality is lying at the borderline between wireless and wire-bound communication network elements, and it is proposed to, firstly, execute a mutual authentication between a mobile device (26) and a new access point (14) using security context information previously transmitted to the new access point. Then, after successful mutual authentication, a handover will be executed from the current access point (12) to the new access point (14).

Abstract: Bleed between two adjacent pigmented inks on a printing medium is reduced. The first ink has at least one neutralized carboxylic acid group, neutralized amine, or a quaternized amine group; and the second ink contains a polymeric dispersant having at least one sulfonate or phosphonate group, and a carboxylic acid additive having a pKa of up to 3.5.
