Abstract:  Digital signatures with homomorphic properties support authentication operations on data. Redactable digital signatures (Redactable Signatures) are a specific type of homomorphic digital signatures that support the deletion of authenticated data. This report will introduce the nature, definition, and representative schemes of the modifiable digital signature, as well as research issues worthy of attention, in combination with application requirements in cloud computing and big data.
