Abstract. We propose new instantiations of chosen-ciphertext secure identitybased encryption schemes with wildcards (WIBE). Our schemes outperform all existing alternatives in term...

A distributed calculus is proposed for describing networks of services. We model service interaction through a call-by-property invocation mechanism, by specifying the security co...

Abstract. We present a non-interactive chosen ciphertext secure threshold encryption system. The proof of security is set in the standard model and does not use random oracles. Our...
Abstract. Whenever agents deal with condential information, it is important that they comply with a principled security policy. We show how the database concept of multi-level sec...
In the setting of secure multiparty computation, a set of mutually distrustful parties wish to securely compute some joint function of their private inputs. The computation should...
