摘要

A method for cryptographically processing a message is disclosed, wherein a first partial cryptographic key and a second partial cryptographic key, which correspond to a decomposition of a private cryptographic key, are used, the message is processed using the first partial cryptographic key resulting in a first partially processed message, the message is processed using the second partial cryptographic key resulting in a second partially processed message and the first partially processed message and the second partially processed message are combined resulting in a cryptographically processed message.
