Provably Secure (Broadcast) Homomorphic Signcryption

International Journal of Foundations of Computer Science, 2019
Signcryption has drawn a lot of attention due to its useful applications in many areas, in particular for applications where the computation and communication resources are constrained, for example, for lightweight devices. The traditional signcryption scheme does not support the homomorphic property. Recent work by Rezaeibagha et al.

Provably Secure Encryption

2002
This chapter deals with provable security. It is desirable that mathematical proofs show that a given cryptosystem resists certain types of attacks. The security of cryptographic schemes and randomness are closely related. An encryption method provides secrecy only if the ciphertexts appear sufficiently random to the adversary. Therefore, probabilistic
