The AES on CUDA application enables massively multithreaded many-core chip with concurrent threads providing huge economies of scale with faster encryption and decryption. CUDA scalable parallel programming model allows programs to run on multiple processors without recompiling.

• Maximize the use of high-bandwidth memory
• Optimizes performance by overlapping memory access with HW computation

• API for memory allocation on device (GPU)
• Free up memory allocated on device
• Memory copy (Host to Host, Host to device, Device to host, Device to Device)
• Synchronizes the host with device
• Error Query Function
• Returns number of bits in cipher key in particular mode.
• Initialization and allocation of memory for AES
• Encryption kernel call
• Decryption kernel call
