The IntelliProp IPC-BL120A-ZM is an AES-XTS Encryption Core supporting 128 or 256 bit encryption. The IPC-BL120A-ZM provides encryption/decryption based on a design principle known as substitution-permutation network (SP-network). An SP-network takes a block of the plaintext (clear data or non-encrypted data) and the key as inputs, and applies several alternating "rounds" or "layers" of substitution boxes and permutation boxes to produce the ciphertext (encrypted data). The IPC-BL120A-ZM is fully verified in pseudo random simulation.
