DSP control and relative technologies have attracted the attention of multi-disciplines engineering researchers and educators, and are becoming a new and active field. This paper gives some discussions about teaching embedded systems in automation major, such as teaching target, course content, teaching methods and course examination. Through four years'… (More)
DSP control and relative technologies have attracted the attention of multi-disciplines engineering researchers and educators, and are becoming a new and active field. Think over the characteristic of DSP course teaching, this article developed the DSP experimental system based on the chip of TMS320LF2407 and XC95144. The experimental system mainly consists… (More)
Cryptography is the fundamental of secure communication. A public key cryptosystem is necessary to realize secure and efficient communication on public network. To construct a public key cryptosystem, it is essential to find a one-way trap-door function. In this paper, we propose a new one-way trap-door function, and present corresponding encryptosystem.… (More)
In this paper, the properties of hyperbolic function are analysed at first; then a key exchange algorithm is proposed which is based on improved hyperbolic function in combination with module computation. Moreover in comparison with the correspondent methods such as RSA and EIGamal etc, our algorithm is proven more secure and practical.
