Abstract
The present disclosure relates to a method and system for securely transferring master keying material between a master dongle (10) and a slave dongle (12). Each dongle (10,12) is connected to a data transfer system. The slave dongle (12) contains a public key and a private key and the master dongle (10) contains master keying material that is to be transferred securely to the slave dongle (12). The data transfer system reads the slave dongle's public key and sends it to the master dongle (10). The master dongle (10) encrypts the master keying material with the slave dongle's public key to produce an encrypted master keying material. The encrypted master keying material is sent via the data transfer system to the slave dongle (12) and the slave dongle (12) decrypts the encrypted master keying material with the slave dongle's private key. This allows multiple users, each having a slave dongle (12a-n) that has been configured in this manner, to use the same master keying material to securely communicate with one another.
