Leakage-Resilient Certificateless Signcryption Scheme Under a Continual Leakage Model

Signature can be used to verify the integrity of both a message and identity signer, whereas encryption ensure confidentiality message. In past, cryptography researchers have studied proposed numerous certificateless signcryption (CLSC) schemes combine benefits signature encryption. However, these may not robust enough withstand side-channel attacks. Through such attacks, an attacker constantly retrieve portion private key system, could eventually recover entire key. Leakage-resilient (LR-CLSC) its security when launches As far as we know, existing LR-CLSC only guarantee under bounded leakage model, where that obtain through attacks is limited. this paper, propose $first$ scheme continual model. Also, demonstrate secure for existential unforgeability ciphertexts indistinguishability against attackers with attacking abilities.
