TLDR
In this article, the authors propose to publish resources in an encrypted form, using corresponding resource keys, published through resource key files, with the publications effectively restricted to authorized peer systems only by encrypting the resource keys in a manner only the authorized peer system are able to recover them.Abstract:
Published resources are made available in an encrypted form, using corresponding resource keys, published through resource key files, with the publications effectively restricted to authorized peer systems only by encrypting the resource keys in a manner only the authorized peer systems are able to recover them. In one embodiment, the resource keys are encrypted using encryption public keys of the authorized peer systems or the groups to which the authorized peer system are members. In one embodiment, the encryption public keys of individual or groups of authorized peer systems are published for resource publishing peer systems through client and group key files respectively. Group encryption private keys are made available to the group members through published group key files. Further, advanced features including but not limited to resource key file inheritance, password protected publication, obfuscated publication, content signing, secured access via gateways, and secured resource search are supported.read more
