A global research project across different universities aims to combine confidential data from all parties while ensuring no single group can see another's raw dataset. Which approach satisfies the requirement of collaboratively calculating results without disclosing each contributor's information?
A distributed cryptographic method that allows participants to compute a shared result from encrypted inputs
A system that uses ephemeral keys to protect connections between hosts
A strategy that rotates symmetric keys at defined intervals
An encrypted process that splits decryption tasks among multiple custodians
A distributed cryptographic method allows participants to process inputs while preserving confidentiality for each group. Splitting decryption tasks among custodians involves managing a secret key rather than enabling group analytics. Rotating symmetric keys mainly handles periodic key replacement and does not support multiparty analysis. Ephemeral keys protect transmissions but do not enable shared computations without revealing data.
