Upgrading Security of Encryption Schemes
Security against Chosen Ciphertext Attacks (CCA security) is the `gold-standard’ for security of public key encryption (PKE) schemes. A major open question in the theoretical study of public key encryption is whether security against Chosen Plaintext Attacks (CPA security) implies CCA security. In this talk, I will discuss some partial progress made towards this question.
This talk is based on joint works with Brent Waters and Susan Hohenberger.
