Abstract
Methods, systems, and devices for data management are described. The described techniques may enable a user to password harden a ciphertext including a first elliptic curve point and an encrypted message such that an unauthorized user may query an enclave multiple times to decrypt the message. For example, the user may generate a second elliptic curve point using a user-provided password and modify the ciphertext using the second elliptic curve point. The user may decrypt the message by restoring the ciphertext and querying the enclave using the restored ciphertext. Accordingly, an unauthorized user may not obtain the message from the enclave unless the unauthorized user obtains the user-provided password or queries the enclave more than once.
