The invention discloses a multi-
chip key synchronization method and
system and
password equipment, and relates to the technical field of
information security. The method comprises the following steps:a scheduling intermediate unit acquiring the
resource use right of a
chip, setting a synchronization key for each
chip in sequence, sending a first key
ciphertext generated by a first chip to a second chip in sequence, and completing the key synchronization operation of the chip if the scheduling intermediate unit receives a synchronization success instruction sent back by each second chip; or, if the scheduling intermediate unit does not receive the synchronization success instruction sent back by the third chip, the first chip regenerating the second key
ciphertext and sending the second key
ciphertext to the second chip in sequence. The chips meeting the service volume can be flexibly selected according to different service requirements, so that the same
password equipment can realizeservice
processing, the chip of the
password equipment does not need to be replaced or the password equipment does not need to be added, the complexity of a
service system is not increased, and the maximum improvement of the service
processing efficiency is realized through minimum cost increase.
