Crypto++ VMAC issue

Well, I tried code available on in my NS-3 project on the following way: inputString = base64_encode (inputString); byte* Kkey = key->GetKey(); byte digestBytes[key->GetSize()]; byte digestBytes2[key->GetSize()]; CryptoPP::VMAC vmac; vmac.SetKeyWithIV(Kkey, key->GetSize(), m_iv, CryptoPP::AES::BLOCKSIZE); vmac.CalculateDigest(digestBytes, (byte *) inputString.c_str(), inputString.length()); //VMAC Verification vmac.SetKeyWithIV(Kkey, key->GetSize(), m_iv, CryptoPP::AES::BLOCKSIZE); vmac.CalculateDigest(digestBytes2, (byte *) inputString.c_str(), inputString.length()); std::string outputString = std::string( (char*)digestBytes, sizeof(digestBytes […]

IP ToS fields with UDPSockets – implementation issue

For the purposes of my project, I needed to add TOS tag to UDP packets which are generated by OLSR routing protocol. In I added ToS Values: // Create a socket to listen only on this interface Ptr socket = Socket::CreateSocket (GetObject (),UdpSocketFactory::GetTypeId ()); socket->SetAllowBroadcast (true); socket->SetIpTos(6); socket->SetIpRecvTos(true); And when I executed the code […]
