摘要:
A method and apparatus for authenticating packets in a controller area network (CAN) are disclosed. The method includes transmitting messages using a mixture of message authentication codes (MACs) in a controller area network (CAN). In addition, a first MAC is generated using a first message and the first MAC is divided into a first MAC part and a second MAC part. A second MAC is generated using a second message and the second MAC is divided into a third MAC part and a fourth MAC part. A linear operation is performed between the second MAC part and the third MAC part to generate a first authentication MAC. The first message is transmitted with the first MAC part and the second message is transmitted with the first authentication MAC.
摘要:
The present invention relates to a peptide derived from the Helicobacter pylori ribosomal protein L1, and the use of this peptide an antibiotic. More specifically, the peptide is derived by making site-specific substitution mutations in a peptide consisting of amino acids 2-20 of the Helicobacter pylori ribosomal protein L1. The resulting peptide has both antibacterial activity and anti-inflammatory activity, but no cytotoxicity.

A composite material for a temperature sensor and a method of manufacturing the temperature sensor using the composite material are provided. The composite material contains four or more kinds of metal oxides combined with highly insulating materials to produce a material with semiconductor-like properties to more accurately measure a temperature at high temperatures in the range of 500° C. and above. The sensor includes electrode wires having a predetermined diameter inserted into the metal oxide of the temperature sensor when the metal oxide is press-molded to form the temperature sensor. Through the connection of the electrode wires to the temperature sensor device, disconnection of the electrode wires from the device even at a high temperature.

Provided are a tape-type fluorine preparation using a biodegradable polymer and a method of preparing the same, and preferably, a tape-type fluorine preparation which is attached to teeth to gradually release fluorine, thereby maintaining a suitable fluorine concentration in an oral cavity, and self-degraded after a certain amount of time, and a method of preparing the same. The tape-type fluorine preparation includes a pressure-sensitive adhesive sheet containing fluorine and capable of being attached to teeth, and the pressure-sensitive adhesive sheet is formed of a biodegradable hydrophilic polymer in an oral cavity to reduce a rate at which the fluorine is released.
