Abstract
Communicating a message via a leakage-deterring encryption scheme. A sender computer stores a public key pkof a recipient key-pair (pk, sk) of a message recipient, a commitment c, bound to the public key pk, to a secret s of the message recipient, and a public key pkof a decryptor key-pair (pk, sk). A receiver computer stores a secret key skof the recipient key-pair (pk, sk), the commitment c and an opening o to the commitment. A decryptor computer stores a secret key skof the decryptor key-pair (pk, sk). The sender computer is adapted to encrypt a message m for the message recipient by generating ciphertexts. The sender computer sends the ciphertexts to the receiver computer. The receiver computer is adapted to send a ciphertext to the decryptor computer and provide a proof. The decryptor computer is adapted to verify the proof.
