Mecanismo de
seguridad que genera series de palabras de paso de un sólo uso. Las palabras de
paso se pueden verificar fácilmente; pero son [computacionalmente] imposibles
de generar salvo por el usuario auténtico.
(I) A security mechanism
that uses a cryptographic hash function to generate a sequence of 64-bit,
one-time passwords for remote user login. [R1760] [RFC4949:2007]
A security mechanism that
uses a cryptographic hash function to generate a sequence of 64-bit, one-time
passwords for remote user login. The client generates a one-time password by
applying the MD4 cryptographic hash function multiple times to the user's
secret key. For each successive authentication of the user, the number of hash
applications is reduced by one.
