Results: First threshold cryptosystems secure in the presence of adaptive adversary in the following two powerful adversarial models:
- Concurrent Model, by Anna Lysyanskaya
- Erasure-Free Model, by Stanislaw Jarecki and Anna Lysyanskaya
[Both results to be presented at Eurocrypt 2000]
In both models, we exhibit cryptosystems secure against adaptive chosen ciphertext attack (the strongest notion of security)
