A system that generates a unique identifier that employs a public key of a cryptographic key pair as a contribution to a name for an attribute associated with a schema. Additionally, a hash over the relevant entity name, version, and culture can be employed to automatically produce the remaining portion of the unique identifier. The innovation can ensure that the unique identifiers used by a schema are mathematically related to a public key in a way that can not be spoofed by malicious agents. To this end, unique identifiers can be computed at installation time by combining the n-bytes of the public key (or a hash, e.g., SHA1, of the public key) with the first n-bytes of another entity-specific hash (e.g., SHA1) computed with respect to specific attributes.
