Increasing in the transistor density in a single chip makes it possible for many-core systems to utilize design space for implementing complex embedded systems. In this paper, we propose an architecture for heterogeneous many-core system to integrate block cipher algorithm which is based on Advanced Encryption Standard (AES). In order to implement AES as a crypto-core along with heterogeneous many-core system two different approaches are proposed. In the first approach, the platform is composed of an AES module, a crypto-core, a network interface, and an internal memory which are managed through a controller. In the second approach, the platform is composed of a Direct Memory Access (DMA), network interface, an internal memory, and a microprocessor in which the AES module is integrated as a crypto-core. Both approaches have been analyzed and compared in terms of area overhead and performance.
