srtp with caam?

[gbiradar]

Hi Guys,

            I'm trying to stream some data using libsrtp. But i thought of using hardware encryption(CAAM) for relaying stream. i'm using openssl with libsrtp.I want to use caam hardware encryption not software encryption with openssl does anyone has idea. please share it. i have security reference manual which doesn't provide much of software coding point of view.

Hello,

  According to section 9 (Security) of “i.MX_Linux_User's_Guide.pdf”:

The CAAM drivers are accelerated through the CryptoDev interface.

   So, it is possible to perform operations with CAAM under Linux

as much as an application uses the CryptoDev interface.

Have a great day,

Hi Yuri​ 

"The CAAM drivers are accelerated through the CryptoDev interface." well i know this i already read all document but my task right now is i have to allow libSRTP to use CAAM hardware encryption.

specifically, how to use cryptodev with libSRTP that i have to know. if you could point any document or link it will be nice. i have to add this feature for project next release. Deadline is very near.

  In order to use OpenSSL engine, some changes should be provided in libsrtp.

Hope the following helps.

libsrtp / Mailing Lists

Yuri.
