Relations Among Notions of Plaintext Awareness
James Birkett and Alexander W. Dent
Abstract
We introduce a new simplified notion of plaintext awareness, which we term PA2I, and show that this is equivalent to the standard definition of PA2 plaintext awareness for encryption schemes that satisfy certain weak security and randomness requirements. We also show that PA2 plaintext awareness is equivalent to PA2+ plaintext awareness under similar security and randomness requirements. This proves a conjecture of Dent that, for suitably random public-key encryption schemes, PA2 plaintext awareness implies PA1+ plaintext awareness.
