Thanks. I saw the libsso code. As made the changes accordingly and its working now.
IV_0 = (count) (4 bytes) IV_1 = (fresh) (4 bytes) IV_2 = (count^(dir<<31)) (4 bytes) IV_3 = (fresh^(dir<<15)) (4 bytes) BRs Amartya -----Original Message----- From: De Lara Guarch, Pablo [mailto:[email protected]] Sent: Monday, July 11, 2016 8:49 PM To: Amartya Kumar Das (MFG & Tech) <amartya.das at wipro.com>; users at dpdk.org Subject: RE: dpdk-users] [Snow 3g Hash API] ** This mail has been sent from an external source ** Hi Amartya, > -----Original Message----- > From: users [mailto:users-bounces at dpdk.org] On Behalf Of > amartya.das at wipro.com > Sent: Friday, July 08, 2016 3:58 PM > To: users at dpdk.org > Subject: [dpdk-users] dpdk-users] [Snow 3g Hash API] > > Hi, > > I am trying to integrate Snow3G API in our stack.

The AAD is the IV passed to the Snow3G f9 function. >From the 3GPP specifications, the IV is (from MSB to LSB): IV_3 = COUNT[0-31] IV_2 = FRESH[0-31] IV_1 = DIRECTION[0] XOR COUNT[0] || COUNT[1-31] IV_0 = FRESH[0-31] So, in your case: IV = 0x00000400, 0x00000000, 0x80000400, 0x00000000 Pablo > > Thanks in advance. > > BRs > Amartya The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain proprietary, confidential or privileged information.
