Abstract
A key-resolution service (KRS) can facilitate a client device in verifying that Content Objects are signed by a trusted entity. During operation, the KRS service can receive an Interest that includes a KRS query for a content name that is to be resolved. The KRS service obtains the content name from the Interest, and obtains a KRS record that includes security information for the content name or a prefix of the content name. The KRS service then returns a Content Object whose payload includes the KRS record to satisfy the first Interest. The client device can query the KRS service to obtain a trusted key associated with at least a name prefix of the Content Object, and if necessary, can disseminate Interests to obtain keys that complete a chain of trust between the trusted key and a key that is used to authenticate the Content Object.
