Abstract: The present invention relates to an application distribution system and method, and the application distribution system according to the present invention includes a developer terminal for requesting registration of an application; and an application trading server for registering and posting the application in an application store in response to the request of the developer terminal, in which if the application does not have an electronic signature, the application trading server performs security verification on the application based on preset application security verification criteria, generates an electronic signature for the application and transmits the electronic signature to the developer terminal, and if the application has an electronic signature, the application trading server performs security verification on the application by verifying the electronic signature.

Abstract: The present inventors intended to search for substances that can regulate the expression of a molecular chaperone, GRP78, using the expression of GRP78 as an indicator. As a result, a novel tetronic acid derivative, versipelostatin compound (also known as JL68) shown in formula (I) having the activity of suppressing GRP78 expression was isolated from the metabolite of Streptomyces versipellis strain 4083-SVS6.

Versipelostatin can be obtained from the culture supernatant by culturing the above-mentioned Streptomyces versipellis strain 4083-SVS6.

Abstract: The present invention discloses a password-based authentication protocol wherein an authentication key is generated with an individual private key of the key servers and a public key of the group of the key servers, which do not store the user's password, and thereby it is possible to protect against a camouflaging server's dictionary attack for accessing the user's password.

Abstract: The present invention discloses a software-based commercial key escrow system (KES) for the PKI environment that enables an entity such as the court to monitor communications of users suspected of unlawful activities while protecting the privacy of law-abiding users.

Abstract: A gamma-compensating circuit has a voltage amplifying unit for amplifying a gamma-compensated picture signal from a broadcasting station and a nonlinear-compensation unit for converting an output amplification degree of the voltage amplifying unit to linearize the amplified gamma-compensated picture signal in accordance with a voltage level of the gamma-compensated picture signal. A linearized amplified gamma-compensated picture signal is obtained from the gamma-compensated picture signal transmitted from a broadcasting station.
