A secret-sharing scheme is a method by which a dealer, holding a secret string, distributes shares to parties such that only authorized subsets of parties can reconstruct the secret. The collection of...
In the Conditional Disclosure of Secrets (CDS) problem (Gertner et al., J. Comput. Syst. Sci., 2000) Alice and Bob, who hold nn-bit inputs xx and yy respectively, wish to release a common secret zz to...
In a kk-party CDS protocol, each party sends one message to a referee (without seeing the other messages) such that the referee will learn a secret held by the parties if and only if the inputs of the...
Our main result applies to exponentially long secrets, and so it should be mainly viewed as a barrier against amortizable lower-bound techniques. We also show that in some natural simple cases (e.g., ...
We present new protocols for conditional disclosure of secrets (CDS), where two parties want to disclose a secret to a third party if and only if their respective inputs satisfy some predicate.
In the \emph{conditional disclosure of secrets} problem (Gertner et al., J. Comput. Syst. Sci., 2000) Alice and Bob, who hold inputs xx and yy respectively, wish to release a common secret ss to Carol...
We initiate a systematic treatment of the communication complexity of conditional disclosure of secrets (CDS), where two parties want to disclose a secret to a third party if and only if their respec...
Many protocols that are based on homomorphic encryption are private only if a client submits inputs from a limited range S. Conditional disclosure of secrets (CDS) helps to overcome this restriction...
