We propose two efficient public key encryption (PKE) schemes satisfying key dependent message security against chosen ciphertext attacks (KDM-CCA security). The first one is KDM-CCA secure with respec...
Re-randomizable RCCA-secure public key encryption (Rand-RCCA PKE) schemes reconcile the property of re-randomizability of the ciphertexts with the need of security against chosen-ciphertexts attacks.
Non-malleability is an important security property for public-key encryption (PKE). Its significance is due to the fundamental unachievability of integrity and authenticity guarantees in this setting,...
Lattice-based public-key encryption has a large number of design choices that can be combined in diverse ways to obtain different tradeoffs. One of these choices is the distribution from which secret ...
For 1≤m≤n1≤m≤n, we consider a natural mm-out-of-nn multi-instance scenario for a public-key encryption (PKE) scheme. An adversary, given nn independent instances of PKE, wins if he breaks at least mm ...
We introduce password-authenticated public-key encryption (PAPKE), a new cryptographic primitive. PAPKE enables secure end-to-end encryption between two entities without relying on a trusted third par...
We propose a framework for achieving a public-key encryption (PKE) scheme that satisfies key dependent message security against chosen ciphertext attacks (KDM-CCA security) based on projective hash fu...
In this paper, we introduce a new framework for constructing public-key encryption (PKE) schemes resilient to joint post-challenge/after-the-fact leakage and tampering attacks in the bounded leakage a...
Lattice based cryptography is one of the leading candidates of the post quantum cryptography. A major obstacle of deployment, though, is that its payload is relatively larger than the classical soluti...
Standardization bodies such as NIST and ETSI are currently seeking quantum resistant alternatives to vulnerable RSA and elliptic curve-based public-key algorithms. In this context, we present Round5, ...
Understanding whether public-key encryption can be based on one-way functions is a fundamental open problem in cryptography. The seminal work of Impagliazzo and Rudich [STOC'89] shows that black-box c...
Sanitizable signature schemes are signature schemes which support the delegation of modification rights. The signer can allow a sanitizer to perform a set of admissible operations on the original mess...
A cryptosystem which supports both addition and multiplication (thereby preserving the ring structure of the plaintexts) is known as fully homomorphic encryption (FHE) and is very powerful. Using such...
In previous work I proposed a fully homomorphic encryption without bootstrapping which has the large size of ciphertext. This tme I propose the fully homomorphic public-key encryption scheme on non-as...
In this paper, we consider a scenario where a sender transmits ciphertexts to multiple receivers using a public-key encryption scheme, and at a later point of time, wants to retrieve the plaintexts, w...
