This invention provides a LAN encryption / decryption accelerator system based on Ethernet communication. First, it implements data communication between the accelerator and the host machine being accelerated through a custom MAC layer protocol. Then, addressing the encryption / decryption task allocation problem under two scenarios—balanced and unbalanced computing power among the slave accelerators—corresponding encryption / decryption task allocation and scheduling methods based on the maximum flow minimum cost algorithm are designed to achieve reasonable allocation of encryption / decryption tasks. Using this accelerator technology and system, the host machine can quickly and efficiently allocate the most resource-intensive encryption / decryption tasks to external hardware accelerators within the LAN via the RJ45 Ethernet port. Any host device within a LAN built on the same router can use this system to perform encryption / decryption operations. This system solves the problem of slow encryption / decryption rates caused by host device performance limitations, successfully improving the encryption / decryption performance of host devices.
