Public key encryption resilient to leakage and tampering attacks

作者：

Highlights：

• Formalize LTR-CCA security w.r.t. both bounded-memory and auxiliary-input leakage.

• Introduce the notion of KH-HPS, and present a generic construction of LTR-CCA PKE.

• Get the 1st PKE secure against both auxiliary-input leakage and tampering attacks.

• Give several instantiations based on some standard number-theoretical assumptions.
