摘要
A cryptographic system (100) is provided for distributing certificates comprising a certificate authority device (110) and multiple network nodes (140, 150, 160). A network node (140) sends a public key to the certificate authority device. The certificate authority device (110) generate a certificate comprising the public key, forms an identifier by applying an identity forming function to the certificate and generates local key material specific for the network node by applying a local key material generation algorithm of an identity based key pre-distribution scheme on the identifier, and sends the local key material encrypted to the network node. The network node may be authenticated implicitly through its access to a shared key obtainable from the local key material.
