Possible Usage Of The Digittrade Hs256S - Digittrade HS256S User Manual

10. Possible usage of the DIGITTRADE HS256S

1) Secure and cost-efficient data transport
The HS256S can be used to transport confidential data. For this both the dispat-
cher and recipient of the data have a smart card with an identical cryptographic
key. The dispatcher only sends the HS256S. As the cryptographic key does not
physically exist (it is on the smart cards), it cannot be read out during transport.
Additionally the HS256S with confidential data can be sent cost-efficiently and
insured by a postal service or courier.
The dispatcher and recipient must check that the HS256S 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 HS256S.
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.
2) Data storage device & authentication separation
Access to the data can be regulated so that it is only possible by i.e. combining
three people. Person X has the HS256S, Person Y has the smart card and person Z
knows the smart card PIN. The three people only meet for the data transfer at the
recipient and separate again afterwards. Persons X,Y and Z cannot gain access to
the data on their own.
