In this work, we develop a framework for building leakage-resilient cryptosystems in the bounded leakage model from puncturable primitives and indistinguishability obfuscation (\(i\mathcal {O}\)). The major insight of our work is that various types of puncturable pseudorandom functions (PRFs) can achieve leakage resilience on an obfuscated street. 
Strong Leakage and Tamper-Resilient PKE from Refined Hash Proof System
TLDR
This work presents an enhanced security against both kinds of attacks, namely strong leakage and tamper-resilient chosen-ciphertext (sLTR-CCA) security, and proposes a generic paradigm achieving this security on the basis of a refined hash proof system (HPS) called public-key-malleable HPS.
Public-Key Cryptography – PKC 2020: 23rd IACR International Conference on Practice and Theory of Public-Key Cryptography, Edinburgh, UK, May 4–7, 2020, Proceedings, Part I
TLDR
The talk will survey some of this work in minimizing well-motivated complexity measures of lower-end primitives that would otherwise seem poorly motivated, and make the case that despite the progress already made, there is much more to be explored.
Witness Maps and Applications
TLDR
A Dual Mode Witness Map (DMWM) is defined which adds an “extractable” mode to a CWM, a relaxation of UWM which maps all the witnesses to a small number of witnesses, resulting in a “lossy” deterministic-prover, non-interactive proof-system.

Leakage-Resilient IND-CCA KEM from the Extractable Hash Proofs with Indistinguishability Obfuscation
Leakage-resilient cryptography requires that a crypto-system remain provably secure even if the attacker gets additional information about the internal states, which is usually the secret key in the

TLDR
This work provides fully secure IBE, HIBE, and ABE systems which are resilient to bounded leakage from each of many secret keys per user, as well as many master keys.
Authenticated Encryption in the Face of Protocol and Side Channel Leakage
TLDR
It is shown how to achieve authenticated encryption that is simultaneously both misuse resistant and leakage resilient, based on a sufficiently leakage resilient PRF, and finally a concrete, pairing-based instantiation of the latter is proposed.
Leakage-Resilient Public-Key Encryption from Obfuscation
TLDR
A compiler is presented that transforms any public-key encryption or signature scheme to one that is continual leakage resilient with leakage on key updates, assuming indistinguishability obfuscation and adapting and optimizing recent techniques of Sahai and Waters STOC 2014 that make any encryption scheme sender-deniable.

Differing inputs obfuscation (diO) is a strengthening of indistinguishability obfuscation (iO) that has recently found applications to improving the efficiency and generality of obfuscation,
Differential Fault Analysis of Secret Key Cryptosystems
TLDR
This work states that this attack is applicable only to public key cryptosystems such as RSA, and not to secret key algorithms such as the Data Encryption Standard (DES).

TLDR
This work constructs public-key encryption schemes, digital signatures, and identity-based encryption schemes that remain secure even if an attacker can leak a constant fraction of the secret memory in each time period between key updates.
