ePrint Report: More Efficient Public-Key Cryptography with Leakage and Tamper Resilience

Shuai Han, Shengli Liu, Dawu Gu

In this paper, we study the design of efficient signature and public-key encryption (PKE) schemes in the presence of both leakage and tampering attacks.


Firstly, we formalize the strong leakage and tamper-resilient (sLTR) security model for signature, which provides strong existential unforgeability, and deals with bounded leakage and restricted tampering attacks, as a counterpart to the sLTR security introduced by Sun et al. …
