专利汇可以提供Certification system for distribution of cryptographic key专利检索,专利查询,专利分析的服务。并且PURPOSE: To eliminate the need for the intervention of an operator at the time of certification in key distribution by certifying a telegraphic message which distributes a key by an RSA cryptography by a digital signature, distributing the password of the telegraphic message, and certifying a telegraphic message which distributes a key by common-use cryptology by using its key password.
CONSTITUTION: A public key PK and a secret key SK are generated at individual node, the PK is made to the public, and the SK is held secret. The digital signature by the RSA cryptography is used for certification at the time of the distribution of a data enciphering key distribution KN. A transmission-side node enciphers a value generated by coupling a password generated at each node couple to the KN by the RSA cryptography and then transmits it. At the time of the certification in the distribution of the data enciphered key (KF), a transmission-side node enciphers the password together with the KF and sends it and a reception-side node certifies the node of the opposite side with the password.
