Security of signed ELGamal encryption [PDF]
, 2005 Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against the adaptive chosen ciphertext attack, in which an attacker can freely use

Identity-Based Cryptography for Grid Security [PDF]
First International Conference on e-Science and Grid Computing (e-Science'05), 2006 The majority of current security architectures for grid systems use public key infrastructure (PKI) to authenticate identities of grid members and to secure resource allocation to these members. Identity-based cryptography (IBC) has some attractive properties which seem to align well with the demands of grid computing.

Efficient Multi-Key FHE With Short Extended Ciphertexts and Directed Decryption Protocol
IEEE Access, 2019 Multi-key full homomorphic encryption (MKFHE) can perform arbitrary operations on encrypted data under different public keys (users), and the final ciphertext can be jointly decrypted by all involved users.
