Evidence of signatures associated with cryptographic modes of operation is established in this work by relying on Lyapunov exponents for estimating the divergence among ciphertexts as the encryption algorithm is applied iteratively.Using our approach it turns out to be possible to discriminate between six modes of operation,namely ECB,CBC,OFB,CFB,CTR and PCBC,for different block ciphers,such as DES,IDEA,TEA,and others.
