WebbBy default, Shield Platform Encryption uses a probabilistic encryption scheme to encrypt data. Each bit of data is turned into a fully random ciphertext string every time it’s encrypted. Encryption doesn’t generally impact users who are authorized to view the data. WebbRSA probabilistic decryption problem. I encountered this problem in an algorithms book and could not see how multiplicative could be used as a probabilistic algorithm. Just an idea: suppose C = P A ( M) is a ciphertext we wish to decrypt, and M is the unknown message. Suppose we can efficiently decrypt some class of ciphertexts C i = P A ( M i ...

An intuitive approach to converting a deterministic encryption scheme into a probabilistic one is to simply pad the plaintext with a random string before encrypting with the deterministic algorithm. Conversely, decryption involves applying a deterministic algorithm and ignoring the random padding.
