In this work we revisit and formally study the notion of proxy cryptography. Intuitively, various proxy functions allow two cooperating parties F (the “FBI”) and P (the “pro...

Informally, Privacy Homomorphism (PH) refers to encryption schemes with a homomorphic property allowing to obtain Ek(a + b) or Ek(a × b) from ciphertexts Ek(a) and Ek(b) without ...

In this paper we introduce the notion of a Public-Key Encryption Scheme that is also a Locally-Decodable Error-Correcting Code (PKLDC). In particular, we allow any polynomialtime ...

Recent studies have shown that an attacker can retrieve confidential information from cryptographic hardware (e.g. the secret key) by introducing internal faults. A secure and re...

This note presents a new way of composing cryptographic primitives which makes some novel combinations possible. For example, one can do threshold decryption using standard block c...
