IP Cores, Inc. Ships an AES Encryption Core Supporting the EAX' Encryption Mode of ANSI C12.22
IP Cores, Inc. . Announces Shipment of an AES Encryption IP Core that Supports EAX’ Block Cipher Encryption Mode for ANSI C12.22.
Palo Alto, California, March 23rd, 2010 --IP Cores, Inc. has shipped an AES encryption IP core supporting the new EAX’ encryption mode.
"Our new GCE1 family of cores supports EAX’, GCM, CCM, and CCM* encryption modes of the AES (Rijndael) cipher," said Dmitri Varsanofiev, CTO of IP Cores. "These are the modes that the designers of chips for wireless or wired remote sensing are typically using. In particular, the well-known EAX mode in its new and simplified EAX’ version has been chosen as a method of encryption and authentication by the authors of the ANSI C12.22 standard for transport of meter-based data over a network. Semiconductor manufacturers working on sensor designs can future-proof their work by using our GCE1 core that supports all the encryption modes used in the standards for remote sensing, both current and upcoming".
EAX and EAX’
EAX mode of operation for cryptographic block ciphers implements authenticated encryption with Associated Data (AEAD) algorithm to simultaneously provide both authentication and privacy for the communication link (so called authenticated encryption) via a two-pass operation, with one pass delivering privacy and one authenticity for each message.
The EAX mode is similar in properties to the extensively used CCM mode, but has some important advantages. EAX is "on-line", i.e., it that can process a stream of data without knowing the total data length in advance and the algorithm can pre-calculate static associated data (AD), which useful for encryption/decryption of communication session parameters (where session parameters may represent the Associated Data).
A simplified version of the EAX mode, so called EAX' , was used by the authors of the the ANSI C12.22 standard for transport of meter-based data over a network.
GCE1 Family of Cores
GCE1 cores implement Rijndael encoding and decoding in compliance with the NIST Advanced Encryption Standard (AES) and encryption/authentication modes GCM, CCM, CCM*, and EAX’. These cores process 128-bit blocks using 128-bit keys and have microprocessor-friendly register interface.
GCE1 datasheet is available on the IP Cores, Inc. Web site at http://ipcores.com/gcm_ccm_eax_ip_core.htm
