The family of IPX-AES IP-Cores provides an efficient FPGA implementation of the Advanced Encryption Standard (AES). Its flexibility allows the combination of several functions and operating modes for a very small FPGA footprint.

The family of IPX-AES IP-Cores is an encryptor / decryptor core range that efficiently implements the Advanced Encryption Standard (AES) as specified in the Federal Information Processing publication FIPS-197 of the National Institute of Standards and Technology in FPGAs.

The IPX-AES module can be customized to ensure its optimization for a wide range of specific application fields with a design architecture that can be adapted to support low up to very high bit-rates. On top of its Multi-Gigabit capability, its flexibility allows combining several functions and operating modes on very small footprints.

功能

With addressing keys of 128 (or 256), the IPX-AES cores execute decryption or encryption.

数据流处理
IPX-AES 内核可以通过两种不同的方式处理数据和密钥。单流选项由一个能够在此密钥的新更新之前使用单个密钥管理数据的核心组成。多流选项是一个功能，能够同时管理多个加密进程，每个进程都基于不同的密钥。

链接模式
数据块间链接支持所有现有模式，这些模式可以单独使用或组合到单个设计中：ECB（电子代码簿）、CBC（密码块链接）、CTR（计数器）。可以支持其他模式。

数据总线
传入、传出和关键数据在公用总线或单独的总线上处理。数据总线宽度为 128 位。

时钟
进程使用单个时钟，可以异步重置。

The modular exponentiation accelerator IPX-RSA is an efficient arithmetic coprocessor for the RSA public-key cryptosystem. It performs the Ae mod M calculation and therefore offloads the most computer-intensive operation of RSA from the main processor. The RSA cryptosystem can be used for public key encryption, decryption and signature/authentication. It is currently the most deployed public key scheme and is used in well-known standards such as SSL/TLS secure internet access, IPSec Virtual Private Networks and S/MIME secure email.

The key advantage of the IPX-RSA IP-Core is its low footprint, thanks to an efficient balance between logic fabric and embedded RAMs and Multipliers.

Taking advantage of its high operating frequency, it is capable of achieving a high throughput of modular exponentiations. As a result, this IP-Core provides a good compromise between processing time and resources compared to general purpose processors.

IPX-RSA 内核的其他功能是自支持和易用性。 IP核在计算过程中，核心不需要与主处理器交互，也不需要基基和指数（A和e）的前期/后计算。它还可通过简单的 32 位处理器总线访问。

IPX-HMAC-SHA-1 IP -Core 是 DCI 文档 v1.2 中指定的内容完整性检查和内容标识所需的哈希功能。它专为 Xilinx 和 Intel FPGA 设备。
IPX-HMAC-SHA-1 是密钥哈希消息身份验证代码标准的实现，它描述了使用加密哈希函数进行消息身份验证的机制。它支持计算音频和视频资产的键控哈希消息身份验证代码 （HMAC）。

This HMAC module uses the SHA1 core in combination with a secret key and the text message provided by the user in order to generate a fixed length MAC value.
The key advantages of the IPX-HMAC-SHA-1 IP-Core are its high throughput and low latency. Its interface can handle a frequency of at least 125 MHz, which is highly suitable for applications like Gigabit Ethernet.
