Lines Matching full:same
156 The same plaintext block always produces the same ciphertext block
157 (for the same key) making it vulnerable to a 'dictionary attack'.
168 The \s-1CBC\s0 mode produces the same ciphertext whenever the same
169 plaintext is encrypted using the same key and starting variable.
175 The use of different starting variables prevents the same plaintext
176 enciphering to the same ciphertext.
185 The \s-1CFB\s0 mode produces the same ciphertext whenever the same
186 plaintext is encrypted using the same key and starting variable.
192 The use of different starting variables prevents the same plaintext
193 enciphering to the same ciphertext.
211 The \s-1OFB\s0 mode produces the same ciphertext whenever the same
212 plaintext enciphered using the same key and starting variable. More
213 over, in the \s-1OFB\s0 mode the same key stream is produced when the same
219 The use of different start variables values prevents the same
220 plaintext enciphering to the same ciphertext, by producing different
238 different from the start variable values used before with the same
240 produced each time from the same parameters. This would be
253 If both keys are the same it is equivalent to encrypting once with
256 If the first and last key are the same, the key length is 112 bits.
260 If all 3 keys are the same, this is effectively the same as normal
269 the same restrictions as for triple ecb mode.
