....additional complexity of guaranteeing adaptive security is the case of using encryption to transform protocols that assume ideally secure channels into protocols that withstand adversaries who hear all the communication. In the non adaptive model standard ChosenCiphertext Attack secure encryption [ddn91,cs98,s99] (or even plain semantically secure encryption [gm84] if used appropriately) is su#cient. To obtain adaptively secure encryption, it seems that one needs to either trust data erasures [bh92] or use considerably more complex constructs [cfgn96,b97,dn00] Clearly, adaptive security implies ....
