Security has always been the toughest challenge in data communication, at the same time it is the biggest necessity in transmitting confidential data. Sensitive data are often at stake when they are deployed in a network. Embedded system design is a very popular research activity as it has a wide range of applications namely, security and surveillance, personal digital assistant, biomedical systems, mobile and pervasive communication gadgets, along with its huge speed compared to very popular software designs. Most of the embedded system applications involve data communication between multiple parties. To add to it, sensor technology requires physically secured systems, which can be dealt with cryptographic and hashing algorithms. However, a parallel implementation of Encryption and Hashing algorithm will cost the efficiency and performance speed of the system. To overcome the shortcomings a multi-core system, capable of parallely executing authentication and encryption is proposed. In this proposal a encryption algorithm and a hash algorithm are placed into two ARM cortex processor of ZYNQ 7020-clg484 FPGA board using ISE 14.4 design suite. The true parallel execution of both algorithms increases system throughput. The soft core IPs(RS232 and Ethernet) are placed in FPGA region to handle realtime data.

The paper designs a new kind of laser marking system which is based on embedded microprocessor with several functions like continuing from the breakpoint, starting from any set point, marking on the curved surface, displaying the trace in real time and so on. The new kind of laser marking system is composed of command module, information collecting and processing module, control module and marking module. The system is improved taking the disadvantages of similar systems off-the-shelf into consideration like poor abilities of dealing with problems on hardware, being unable to communicate and so on. It not only can meet different requirements of various users but is also more user-friendly, more stable and safer. So it is of great practical value.
