The cipher block chaining (cbc) mode has the property that itrecovers from errors in ciphertext blocks. show that if an erroroccurs in the transmission of a block , but all the other blocks are transmittedcorrectly, then this affects only two blocks for decryption, whichtwo blocks?

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
