On Key Substitution Attacks Against Aggregate Signatures and Multi-Signatures

open access: yesIEEE Access
The most fundamental security requirement for signature schemes is unforgeability, which guarantees that no one can create a valid signature on a message without the secret signing key.

Identity-based key-insulated aggregate signature scheme

open access: yesJournal of King Saud University: Computer and Information Sciences, 2017
Private key exposure can be the most devastating attack on cryptographic schemes; as such exposure leads to the breakage of security of the scheme as a whole. In the real world scenario, this problem is perhaps the biggest threat to cryptography.
