Abstract
Provided are a computer program product, system, and method for generating master and wrapper keys for connected devices in a key generation scheme. For each of the devices, a wrapped master key comprising a master key for the device and a wrapper key is stored. The wrapper keys for a plurality of the devices are generated by another of the devices. For each of a plurality of the devices, the master key for the device is used to generate the wrapper key for a target device comprising another of the devices. For each of the devices, the wrapper key for the device is used to decrypt the stored wrapped master key. At least one of the devices uses the master key for the device to encrypt and decrypt data at the device.
