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.
