Abstract
The invention relates to a method for distribution of a set of credentials from a credential issuer to a credential user. The credential user is provided with a user device. A first channel and a second channel are provided for communication between the user device and the credential issuer. A shared key is distributed between the user device and the credential issuer by means of the second channel. A binary representation of the set of credentials with a predefined maximum level of deviation from a uniform distribution is generated. The binary representation of the set of credentials is encrypted by means of the shared key. The encrypted set of credentials is distributed via the first channel from the credential issuer to the user device. The encrypted set of credentials is decrypted by the user device by means of the shared key.
