keyword Question

I need help in finding the keyword for this problem:

Plain: abcdefghijklmnopqrstuvwxyz
cipher: zqxpeonmwlkjhgfdbvyutricsa

I have tried charts of different lengths and patterns such as:

zpnl etg
qemk bhc
xowj mso
                  xyz

I put the cipher alphabet in alphabetical order:

Plain: zqxpeonmwlkjhgfdbvyutricsa
cipher: abcdefghijklmnopqrstuvwxyz

I see that both alphabets are running in opposite directions.
I seperated the letters that seemed to be part of the keyword, and
tried
to create a word with those letters and came up with "security"

Plain: yextvwuszqponmlkjhgfdbrica
Cipher: securityabdfghjklmnopqvwxz

It only works because I know where the plain alphabet letters are
suppose to go.
Can anyone give me a little help?
