The presented messaging protocol uses three new public keys in a signed and encrypted message to achieve backward security and recovery in an environment where an attacker now and then obtains the security parameters in exposed, decrypted form.

New to the current state of the art is that a message contains history data: a list of recently used public keys and their Diffie-Hellman counterparts. Also new is the usage of a stored and pseudorandomly changing data used together with a just computed Diffie-Hellman shared secret to provide a value that an attacker cannot produce if he does not have a proper exposed security data and the private key required to compute the Diffie-Hellman shared secret.

In the mass production of dielectric resonator oscillators (DROs), it is necessary to regulate the position where a dielectric resonator is placed with a high degree of accuracy and thus time required for the assembly work increases undesirably. Further, a terminating resistor and earthing means are formed at an end of a transmission line that is electromagnetically coupled to the dielectric resonator and constitutes the resonator on a dielectric substrate, and as a result the production cost increases. The present invention is characterized in that, in the components of a DOR, only a transmission line is formed on a dielectric substrate, and an oscillating active element and a terminating resistor and the earthing means on an MMIC chip are connected to the transmission line with metallic wires, metallic ribbons, or the like. Further, an open stub is formed in the middle of the transmission line on the side close to the oscillating active element when it is viewed from the dielectric resonator.

The process is preferably performed without adding polymer seed prior to polymerization kick-off.

The present invention is directed to two component coating compositions that cure under ambient conditions and more particularly to those having low VOC (volatile organic content) that are suitable for use in automotive refinish and Original Equipment Manufacturing (OEM) applications. The coating composition includes crosslinkable and crosslinking components, wherein the crosslinkable component includes a low polydispersity, low molecular weight copolymer having on an average 2 to 25 functional groups, such as hydroxyl, carboxyl, acetoacetoxy, primary and secondary amine, and epoxy. The copolymer is polymerized from a monomer mixture that includes one or more non-functional acrylate monomers and one or more functional methacrylate monomers provided with the functional groups. The crosslinking component includes polyisocyanate, polyamine, ketimine, melamine, epoxy, polyacid or a combination thereof. The invention is also directed to coating produced from the coating composition.

A clarifying agent composition comprises a diacetal powder and an organosilane treated fume silica having a pH value of 5.5 to 8, measured in a 4% w/w dispersion in 1:1 mixture of water-methanol. The diacetal has the general structure formula (I), (II), (III), (IV) or (V), wherein R1 and R2 are independently selected from the group consisting of H, C1-C4 alkyl, C1-C4 carbalkoxy, F, Cl, and Br; a is 0, 1, 2 or 3; b is 0, 1, 2 or 3 and n is 0 or 1. The organosilane treated fume silica is dispersed in the diacetal powder and being 0.05˜50% by weight the clarifying agent composition. This invention also intents to provide a new manufacturing method for preparing superfine powdery diacetal composition with high dispersion characteristic the use of said compositions for preparing polyolefin plastic article without the visible white spots on the surface of the corresponding article.
