Pci Encryption Decryption Controller -

Modern data centers and secure embedded systems require line-rate cryptographic processing without burdening the CPU. Traditional software-based encryption (e.g., dm-crypt, IPsec) suffers from high context-switch overhead. A dedicated PCIe encryption controller offloads the entire cipher operation, acting as a cryptographic coprocessor.

A PCI Encryption/Decryption Controller is a hardware or software component designed to manage the encryption and decryption of payment card data. It is a critical element in the payment processing ecosystem, responsible for securing sensitive information such as credit card numbers, expiration dates, and card verification values. pci encryption decryption controller
