Security & Encryption IP-cores by intoPIX

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 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.

Functions

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

Traitement des flux de données
Les cœurs IPX-AES peuvent gérer les données et les clés secrètes de deux manières différentes. L'option de flux unique consiste en un noyau capable de gérer les données avec une seule clé, avant une nouvelle mise à jour de cette clé. L'option de flux multiples est une fonction capable de gérer plusieurs processus de chiffrement ensemble, chacun basé sur une clé secrète différente.

Modes de chaînage
L'enchaînement inter-blocs de données supporte tous les modes existants qui peuvent être utilisés séparément ou combinés en un seul modèle : ECB (Electronic Code-Book), CBC (Cipher Block Chaining), CTR (Counter). D'autres modes pourraient être pris en charge.

Bus de données
Les données entrantes, sortantes et clés sont traitées sur des bus communs ou séparés. La largeur du bus de données est de 128 bits.

Horloge
Les processus utilisent une seule horloge et peuvent être réinitialisés de manière asynchrone.

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.

Other features of the IPX-RSA core are self-support and ease of use. The IP-Core needs no interaction with the main processor during computation and requires no pre/post computation of the base and exponent (A and e). It is also accessed through a simple 32-bit processor bus.

IPX-HMAC-SHA-1 IP-Core is the hashing function required for the content integrity check and content identification as specified in DCI document v1.2. It is designed for Xilinx and Intel FPGA devices.
IPX-HMAC-SHA-1 is an implementation of the Key Hashed Message Authentication Code standard, which describes a mechanism for message authentication using cryptographic hash functions. It enables computation of the keyed hash message authentication code (HMAC) for audio and video assets.

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.
