Security notions for stateful signature schemes
2021
IET Information Security
In some digital signature schemes, the signer needs to maintain a dynamic state while signing messages. These are called stateful signature schemes. Although stateful signature schemes are commonly used as cryptographic primitives, they do not fit the standard definition of a signature scheme in cryptography. In this work, formal and general definitions for stateful signature schemes are given. In the definitions of security notions, various scenarios are considered where the adversaries have
