Possible Usage Of The Digittrade Hs128/Hs256 - Digittrade High Security HS128 User Manual

9. Possible usage of the DIGITTRADE HS128/HS256

1) Secure and cost-efficient data transport
The HS128 / HS256 can be used to transport confidential data. For this both the
dispatcher and recipient of the data have a smart card with an identical crypto-
graphic key. The dispatcher only sends the HS128 / HS256. As the cryptographic
key does not physically exist (it is on the smart cards), it cannot be read out during
transport. Additionally the HS128 / HS256 with confidential data can be sent cost-
efficiently and insured by a postal service or courier.
The dispatcher and recipient must check that the HS128 / HS256 has not been
tampered with during transport. Pay special attention to the DIGITTRADE security
seals. You can also take other security measures like a sealed packaging. This is
also effective for all other transport possibilities of the HS128 / HS256.
For additional security, the use of multiple smart cards with different
cryptographic keys, (deposited at the dispatcher and recipient) which can be used
to decrypt or encrypt the data in a chosen sequence.
