On Key Substitution Attacks Against Aggregate Signatures and Multi-Signatures
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
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.

Cryptanalysis of Compact Certificateless Aggregate Signature Schemes for HWMSNs and VANETs
Certificateless cryptosystems resolve the critical problems in public-key cryptosystems and identity-based cryptosystems. A certificateless aggregate signature scheme aggregates multiple signatures of multiple signers into a single signature that ...
