Subject: [PATCH v2 00/12] crypto: atmel-authenc: add support to authenc(hmac(shaX),Y(aes)) modes
Date: Thu, 22 Dec 2016 17:37:49 +0100 [thread overview]
Message-ID: <cover.1482424395.git.cyrille.pitchen@atmel.com> (raw)
Hi all,
this series of patches has been based and tested on next-20161222 with
CRYPTO_MANAGER_DISABLED_TESTS not set.
The series adds support to the hmac(shaX) algorithms first, then combines
both the Atmel SHA and AES hardware accelerators to implement
authenc(hmac(shaX),Y(aes)) algorithms as used by IPSEC/SSL connections.
It has also been tested with strongswan + xl2tpd to create an IPSEC+L2TP
(transport mode) VPN and strongswan only (tunnel mode) for an IPSEC VPN.
Then iperf was used to measure the bandwidth improvement in tunnel mode:
drivers AES SHA SPLIP iperf half-duplex
Mbit/s
authenc(hmac(sha1-generic),cbc(aes)) SW SW N/A 27.7
authenc(hmac(sha1-generic),atmel-cbc-aes) HW SW N/A 30.2 (mainline)
authenc(atmel-hmac-sha1,atmel-cbc-aes) HW HW no 29.1
atmel-authenc-hmac-sha1-cbc-aes HW HW yes 38.8
SPLIP: Secure Protocol Layers Improved Performances (AES+SHA combined).
Some patches of this series are purely transitional: I've split the
modifications into many patches to ease the review.
Best regards,
Cyrille
