Instead of 

Friend WithEvents SerialPort1 As System.IO.Ports.SerialPort

Use

Public WithEvents SerialPort1 As System.IO.Ports.SerialPort

private MainForm mainForm = null;

public SecondForm(MainForm mainForm) <---- constructor
{
    ...
    this.mainForm = mainForm; <---- save reference to main form
    ...
}

private void UseSerialPort()
{
    // do something with the serial port here
    SerialPort sp = mainForm.SerialPort; <---- access the member on the main form
}

private void OpenSecondForm()
{
    SecondForm secondForm = new SecondForm(this); <----- pass the instance of the main form here
    secondForm.Show();
}

byte[] PlainTextBytes = new byte[CipherText.Length];
int ByteCount = cryptoStream.Read(PlainTextBytes, 0, PlainTextBytes.Length);

MemoryStream memStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(memStream, Decryptor, CryptoStreamMode.Write);
cryptoStream.Write(CipherText, 0, CipherText.Length);
PlainTextBytes = memStream.ToArray();

private byte[] PerformTransform(byte[] data, ICryptoTransform tran)
{
    // create a memory stream to hold data and a cryptostream to do the transformation
    MemoryStream ms = new MemoryStream();
    CryptoStream cs = new CryptoStream(ms, tran, CryptoStreamMode.Write);
    // input the data to the crypto stream so it can transform it
    cs.Write(data, 0, data.Length);
    // close the crypto stream and let it flush and finalize
    cs.Close();
    // return the transformed data from the memory stream
    return ms.ToArray();
