Question: You ( Eve ) have intercepted two ciphertexts: c 1 = 1 1 1 1 1 0 0 1 0 1 1 1 1 0

You (Eve) have intercepted two ciphertexts:
c1=1111100101111001110011000001011110000110 KeyGen: Enc(k,m in {0,1}\lambda ): k {0,1}\lambda return k &m return k 18

c2=1111101001100111110111010000100110001000
You know that both are OTP ciphertexts, encrypted with the same key. You know that either c1 is an encryption of alpha and c2 is an encryption of bravo or c1 is an encryption of delta and c2 is an encryption of gamma (all converted to binary from ascii in the standard way).
Which of these two possibilities is correct, and why? What was the key k?
