The Study Of Unique Signal And Encryption Technology Of MEMS Discriminator

MEMS discriminator is a security device used in high consequence system, which can prevent power outside from entering into forbidden zone without permission. The sole key to the discriminator is the unique signals. The secure topic of MEMS discriminator spans a range of four issues: isolation; incompatibility; inoperability; independence. Advantages of the discriminator based on MEMS technology are high reliability, small size and low price. Therefore, it has the potential of application in military, information and finance security. By analyzing the results of former research, our team developed a new discriminator based on MEMS technology. With the merits of high reliability and auto reset function, this device was successfully integrated into the systems of computer authentication, and, furthermore, it's potential of application in hard disc encryption was proved by several experiments.
