AES-CTR Encryption IP Core

The IntelliProp IPC-BL204A-ZM AES-CTR Encryption IP Core is a production-hardened cryptographic engine designed to provide high-speed, stream-based data encryption and decryption. By implementing the Advanced Encryption Standard in Counter (CTR) mode as defined in NIST SP 800-38A, the core converts a block cipher into a stream cipher, enabling parallelized keystream generation and zero-latency data path processing.

Engineered for seamless integration within high-speed storage, networking, and embedded SoC datapaths, the IPC-BL204A-ZM encrypts and decrypts streaming data payload blocks directly in hardware logic. Because CTR mode allows keystream blocks to be computed in advance or in parallel, the core delivers maximum line-rate throughput and minimal processing latency without introducing pipeline bottlenecks.

Delivered as clean, fully synchronous RTL, the IPC-BL204A-ZM supports both 128-bit and 256-bit key sizes (AES-CTR-128 and AES-CTR-256) and features flexible bus interfaces, making it ideal for integration into PCIe, NVMe, SATA, and custom FPGA or ASIC architectures.

Features

• Standards Compliance: Fully compliant with NIST SP 800-38A (CTR Mode) and NIST FIPS 197 Advanced Encryption Standard (AES) specifications.
• Stream Cipher Efficiency: Counter mode implementation allows symmetric encryption and decryption operations using identical hardware logic structures.
• Strong Cryptographic Key Support: Fully supports both 128-bit and 256-bit AES key lengths (AES-128 and AES-256) for robust data protection.
• Parallelized High-Throughput Processing: Fully pipelined architecture enables parallel keystream generation to maintain deterministic, line-rate performance.
• Ultra-Low Latency Operation: Direct XOR combining of plaintext/ciphertext with pre-computed keystream streams eliminates data path latency delays.
• Configurable Data Bus Widths: Flexible interface options supporting standard 32-bit, 64-bit, 128-bit, or 256-bit system bus architectures.
• Random Access Capability: Supports direct, independent encryption and decryption of arbitrary data blocks without requiring sequential state processing.
• Synchronous Synthesizable RTL: Delivered as high-quality, fully synchronous Verilog source code or netlist optimized for rapid placement, routing, and timing closure across modern FPGAs and ASICs.
