about

DigSigs are the first choice when you want to establish accountability, detect data manipulation, and ensure data integrity even in environments with limited connectivity. The item identifier (e.g. a barcode) must be trusted immediately wherever the item is subject to decisions and actions, including obtaining additional information about the item. For example, fishing and camping permits in remote areas.

Digital signatures, and therefore DigSigs, are based on a tried and tested technology used by most web server operators and all financial systems. The success of digital signatures is based on public key cryptography where a secret private key is used to create a digital signature and its public key pair isused to verify the signature. The encryption methods and best practice procedures have been developed, improved and standardised over many years and are actively maintained for security now and into the post-quantum era.

At TÖNNJES, we use DigSigs successfully throughout the entire life-cycle of licence plates controlled by authorities: from globally organised production, distribution, and personalisation to issuance and return.
