I'm looking for Test Vectors to test my implementation of PRESENT. I would like to test a different input from the usual where the key and the plaintext are either 000..000 or FFF...FFF.

There are many sources presenting the test vectors.

But you can also extract it from sourcecode implementations as opencores.org et al offer them…

 Plaintext: 0000000000000000

 Key: 00000000000000000000 (80-bit)

    $\begingroup$ Aren't those round keys of 80 bits? $\endgroup$

In the original paper (pp. 16) one can find the requested test-vectors.
The paper includes test vectors for all four cases you request (one or both of key and plaintext are $00...00$ or $FF...FF$).
The following table shows the test vectors:

Plaintext         | Key                    | Ciphertext
00000000 00000000 | 00000000 00000000 0000 | 5579C138 7B228445
00000000 00000000 | FFFFFFFF FFFFFFFF FFFF | E72C46C0 F5945049
FFFFFFFF FFFFFFFF | 00000000 00000000 0000 | A112FFC7 2F68417B

    $\begingroup$ While the phrasing in the question may be a bit ambiguous, the way I interpret it is that the OP would like some other test vectors than these "usual" ones, for further testing. $\endgroup$ Dec 14, 2015 at 15:25
Plaintext Key Ciphertext
00000000 00000000 00000000 00000000 0000 5579C138 7B228445

I was not able to get the round keys that are mentioned above. I got the below round keys and in the end, got the expected result.

For the first test case the round keys (PRESENT-80) are as follows:

Round Key 1:C0000000000000008000
Round Key 2:50001800000000010000
Round Key 3:60000A00030000018000

Round Key 5:900016000180002A800C
Round Key 6:0001920002C000330005
Round Key 7:A000A0003240005B8006
Round Key 8:D000D4001400064C000B
Round Key 9:30017A001A80028480C9
Round Key 10:E01926002F4003550050

  • $\begingroup$ Those do appear to be the same round keys but without the 0th round key which is direct use of the input key. I think that your implementations are in agreement. $\endgroup$

    $\begingroup$ Ya, my bad. Just noticed that they're all missing last 4 bytes of the key. Otherwise they're the same. Just pasted this for debugging purposes. $\endgroup$
