Design Of Anti-theft Encryption System For Storage Battery

The purpose of this essay is to develop a new encryption system of battery to guard against thief which is in the basis of embedded system. By means of research of secondary source collection, relevant evidence is selected, evaluated and organized into the crucial aspects:using the method of digital circuit encryption to solve the problem of the theft and loss of storage battery in people's daily lives. In order to find the solutions, a new asymmetric key cryptography which is on the chip design technology is used and combined with the characteristics of embedded system. The relevant soft wares such as Quartusâ…¡,ModelSim-Altera are applied to constructs a system of relevant soft wares and hard wares. Through which makes the chip embedded into the interior of the storage battery and make the battery has to be certificated by the randomly generated key or password before it is working. Hence, an active anti-theft system is established. The characteristics of the system are:the digital management technology, the privacy system of hardware, the sleep technology of control of circuit board etc. Also, the Mathematical theory encryption such as "integer factorization and primality testing" is applied, through which makes the system key with a stronger security and a higher function of prevent deciphering.
