Sometimes error propagation is an issue when choosing a mode of operation in practice. In order to analyze the propagation of errors, let us assume a bit error (i.e., a substitution of a 0 bit by a 1 bit or vice versa) in a ciphertext block y_i.

1. Prepare an overview of the effect of bit errors in a ciphertext block for the modes ECB, CBC, CFB, OFB and CTR. Differentiate between random bit errors and specific bit errors when decrypting y_i.
