AES-GCM

Advanced Encryption Standard, AES, is the most widely used block cipher (symmetric encryption) and functions by encrypting a 128-bit block of data using an either 128, 192, or 256-bit key. AES is a symmetric encryption algorithm, where the same key is used for both encrypting and decrypting a message. Xiphera provides AES block cipher IP cores that support a range of operation modes, including CTR, GCM, CBC, OFB, CFB, and XTS. For versatility with dynamically selectable modes, we offer Versatile AES-256 IP core.

AES-GCM is a widely used cryptographic algorithm for Authenticated Encryption with Associated Data (AEAD) purposes, as it provides both data confidentiality and authenticity. For the extremely high-performance demands, we offer our extreme-speed AES-GCM IP core which achieves several hundreds of Gbps of throughput on modern architectures. The extreme-speed AES-GCM IP core is able to handle messages without additional message-specific delay ensuring a continuous processing flow. All our IP cores are engineered for seamless integration into FPGA and ASIC designs using a vendor-neutral design approach, and their functionality is independent of any manufacturer-specific FPGA features. It’s important to highlight our AES-GCM IP cores are validated under the NIST CAVP program.
