Overview

These high performance cores have been designed to provide hardware acceleration of the underlying 802.11 WPA security algorithms, which in combination with the Helion AES-CCM core family, may be used to implement a full 802.11i WPA2 security solution very efficiently in Xilinx FPGA. The security processing is split into two parts, since they are likely to be required at different points within the MAC subsystem.

The Helion WEP/TKIP Encryption engine is a standalone high-speed processing core which is designed to encrypt and decrypt 802.11 MPDU data, based on an underlying ARC4 stream cipher. It includes all the defined keymix processing as well as the MPDU payload encryption/decryption functionality.

The Helion TKIP Michael engine is a standalone high-speed processing core which is designed to accept 802.11 MSDU data and use it to generate a compliant “Michael” authentication tag. The Michael tag is typically appended to an outgoing MSDU for encryption, or compared with a decrypted incoming tag for authentication checking

Bringing IPsec into the Quantum Safe Era

Over the next five years, all security protocols and public key cryptography will undergo a comprehensive overhaul to ensure quantum safety. This represents the most significant change in these domains since the advent of public key cryptography.

How to design secure SoCs, Part V: Data Protection and Encryption

In today’s connected world, where data is a crucial asset in SoCs, Part V of our series explores how to protect and encrypt data, whether at rest, in transit, or in use building on our earlier blog posts of the series: Essential security features for digital designers, key management, secure boot, and runtime integrity.

Cryptography Does Not Equal Security

At Rambus, we often receive RFIs, RFPs and RFQs for security silicon IP cores to be used in our customer’s next semiconductor product. Such requests often contain a long shopping list of required cryptographic algorithms, their modes of operation, their key lengths or strengths and performance and sizing requirements.
