Design And Implementation Research Of Application Specific Cryptographic SoC

With the progress of information technology, the Application Specific Cryptographic SoC (ASC-SoC) plays a main role in secure system. In this work, We study the design method of ASC-SoC and present an 8-bit ASC-SoC chip designation named ETISOC, with 33MHz working frequency. This system can service for every kind cryptographic functions with high performance in embedded micro-cryptographic system.Our works are given below:1. With the technology of software/hardware partitioning, we study the method of ASC-SoC designation, and give its application -- ETISOC chip designation. The research obtains some exciting results. The implementation of this design not only has high speed, but also with facility and can fully fulfill all the demands of embedded cryptographic systems such as smart card,USB-key etc.2. The design of an MCS-8052 compatible MCU ETI-8052 is presented. It contributes a core role in cryptographic SoC systems, by extending the basic operation such related to cryptographic functions. The use of fully synchronous technology reduces the chip area, supplies more cryptographic functions in SoC systems, and promotes the speed of instruction execution by 8-10 times.3. The management of memory is proposed in the optimization design of ASC-SoC. This method can rebuild the chip operating system and reuse the resource in ASC-SoC chip. By using of the method, ETISOC can service in more and more applications.4. By analyzing the characteristics of device interfaces, we design the RS232 and ISO7816-3 interface. The system bus technology achieves remarkable resources reduction in ASC-SoC chip.5. In this work we study the generating methods of true random number by using the theory of combination loops and coin toss. The design can be built in digital logic.6. In order to accelerate the generation of large prime, a new scheme using the abort strategy and incremental products is presented. This scheme presents a higher speed of the large prime generation compare with the common.
