### L4
The ELLI method can be used to identify an RFID tag.
Can you run the following code and determine that it works (C and D should be the same)? Can you also explain how it works?
```Python
from os import urandom
from eccsnacks.curve25519 import scalarmult, scalarmult_base
import binascii
lamb = urandom(32)
a = scalarmult_base(lamb)
eps = urandom(32)
b = scalarmult_base(eps)
c = scalarmult(eps, a)
d = scalarmult(lamb, b)
print "RFID private key: ",binascii.hexlify(eps)
print "Reader private key: ",binascii.hexlify(lamb)
print
print "A value: ",binascii.hexlify(a)
print "B value: ",binascii.hexlify(b)
print "C value: ",binascii.hexlify(c)
print "D value: ",binascii.hexlify(d)
```
