Two files encrypted with related data versus one file "AES" is certainly not IND-CPA secure. A probabilistic encryption scheme such as CBC, CTR, OFB, .. is. |

How compared encryption algorithm in terms of efficiency No, there isn't. Big-O complexity is asymptotic - in addition to being an average - and is generally not accurate for realistic key sizes. In addition, some theoretically fast algorithms are terribly slow because they are not amenable to an efficient implementation, etc.. your best bet is to measure it, IMHO. |

Is it safe to use RSA as a proof-of-work system? re: last edit, in fact I suspect the client can compute the proof asymptotically just as fast as the server can as $k$ increases, making the scheme useless. I will update my answer as well as it is now misleading. |

AES CBC mode or AES CTR mode recommended? Please show some research effort in your questions.. and they can both be made just as secure if done right. They both have their pros and cons and target different uses. |
