Modalidad de cifrado de bloques en la cual cada
bloque se cifra independientemente de los demás, sin realimentación del texto
cifrado sobre el propio dispositivo criptográfico (ISO-7498-2). [Ribagorda:1997]
(N) A block cipher mode in
which a plaintext block is used directly as input to the encryption algorithm
and the resultant output block is used directly as cipher text [FP081]. (See: block cipher, [SP38A].) [RFC4949:2007]
The simplest of the
encryption modes is the electronic codebook (ECB) mode. The message is divided
into blocks and each encrypted separately. The disadvantage of this method is
that identical plaintext blocks are encrypted into identical ciphertext blocks;
thus, it does not hide data patterns well. In some senses, it doesn't provide
serious message confidentiality, and it is not recommended for use in
cryptographic protocols at all.
