The Trusted Data Format (TDF) is a data object encoding specification for the purposes of enabling data tagging and cryptographic security features. These features include assertion of data properties or tags, cryptographic binding and data encryption.
The abstract machine TDF (originally the Ten15 Distribution Format, but more recently redefined as the TenDRA Distribution Format) evolved at the Royal Signals and Radar Establishment in the UK as a successor to Ten15. Its design allowed support for the C programming language.
