Abstract

The invention discloses a bidirectional authentication electronic detonator system and a control method thereof. A superior management computer generates a public key, a private key and a key expiration date according to a blasting scheme, sends the public key and an ID number to an electronic detonator one by one, and sends the key expiration date and the private key to an authentication key; a register reads the private key in the authentication key, encrypts a register instruction by using the private key, and sends to the electronic detonator; the electronic detonator decrypts the register instruction by using the stored public key, encrypts the own ID number by using the public key, and feeds the encrypted ID number to the register; the register decrypts with the private key to obtain the ID number of the electronic detonator, and then the bidirectional authentication is completed; and when the use time of the authentication key exceeds the set key expiration date, the key in the authentication key fails. According to the bidirectional authentication electronic detonator system and the control method thereof, the information attack resisting capacity of an existing electronic detonator initiation system is greatly improved, the danger of illegal operation of the detonator through a fake communication instruction is avoided, and the danger of illegal operation of the detonator within non blasting work time is avoided.

Description

technical field [0001] The invention relates to the detonation technology of pyrotechnic products, in particular to an electronic detonator system with two-way authentication and a control method thereof. Background technique [0002] Since the 1980s, electronic detonators have been developed internationally. With the rapid development of electronic technology, microelectronic technology and pyrotechnics technology, electronic detonator technology has made great progress. After 2000, our country also carried out a lot of electronic detonator research. At present, electronic detonators have higher safety and high delay accuracy than traditional electric detonators. But its security is not impeccable. Existing electronic detonators adopt a one-way authentication method, that is, the registrar unidirectionally authenticates the ID number of the detonator to increase the difficulty of illegal detonation. However, there are still security risks in this way. After the detonat...
