Secret-Sharing from Robust Conditional Disclosure of Secrets
cryptographic protocols secret sharing
2019/5/21
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...
Placing Conditional Disclosure of Secrets in the Communication Complexity Universe

2018/12/3
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...
Optimal Linear Multiparty Conditional Disclosure of Secrets Protocols
Secret-sharing schemes conditional disclosure of secrets protocols
2018/5/15
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...
Conditional Disclosure of Secrets and d-Uniform Secret Sharing with Constant Information Rate
secret sharing information-theoretic cryptography
2018/1/12
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., ...
New Protocols for Conditional Disclosure of Secrets (and More)
secret sharing information theoretic
2017/4/27
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...
Communication Complexity of Conditional Disclosure of Secrets and Attribute-Based Encryption.

2015/12/29
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...
A New Protocol for Conditional Disclosure of Secrets And Its Applications
Conditional disclosure of secrets crypto-computing homomorphic encryption
2009/3/12
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...
