Abstract
Stateful hash-based signatures can be implemented using a secure device. For example, a computing device can transmit a request to a secure device to obtain a partial digital signature usable to cryptographically sign data, where the secure device is separate from the computing device. The secure device can generate the partial digital signature using a private key, which is generated by the secure device based on a counter value. The counter value is maintained internally to the secure device. The computing device can then receive, from the secure device, the partial digital signature and the counter value corresponding to the private key. The computing device can construct a full digital signature, to cryptographically sign the data, based on the partial digital signature and the counter value.
