Why is it not desirable to reuse a stream cipher key? stream cipher is one that encrypts a digital data stream one bit or one byte at a time. A block cipher is one in which a block of plaintext is treated as awhole and used to produce a ciphertext block of equal length, // If two plaintexts are encrypted with the same key using a stream cipher, thencryptanalysis is often quite simple. If the two ciphertext streams are XORedtogether, the result is the XOR of the original plaintexts. If the plaintexts aretext strings, credit card numbers, or other byte streams with known properties,then cryptanalysis may be successful

Why is it not desirable to reuse a stream cipher key? If two plaintexts are encrypted with the same key using a stream cipher then cryptanalysis is often quite simple. If the two ciphertext streams are XORed together the result is the XOR of the original plaintexts. So it is not desirable to reuse a stream cipher key.
