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
