At Crypto'07, Goyal introduced the concept of Accountable Authority Identity-Based Encryption as a convenient tool to reduce the amount of trust in authorities in Identity-Bas...
In this work, we design a method for creating public key broadcast encryption systems. Our main technical innovation is based on a new “two equation” technique for revoking us...
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 ...
This paper describes a secure and reliable method for storing data in a distributed hash table (DHT) leveraging the inherent properties of the DHT to provide a secure storage subs...
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
