What is Guardtime?

Guardtime offers a web-scale digital signature system for electronic data that uses only hash function based cryptography, creating a Keyless Signature Infrastructure. The main innovations are a distributed delivery infrastructure, which is designed for scale, and the removal of the need to rely on cryptographic keys for signature verification.

Keyless Signatures are a combination of hash function based server-side signatures and hash-linking based digital timestamping, delivered using a distributed and hierarchical infrastructure. The digital timestamp component of the service is officially certified and Guardtime is accredited as a signature authority by the European Union.
