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.
