n adversary to recover the key by using a standard time-memory trade-off strategy. On its best setting the attack has a complexity as low as 2 ·2., while this should be 2. for a good scheme. Taking AES-128 as an example this would result in an attack with complexity of 2..

very much relevant to the design of animated CAPTCHAs. In this paper, we show that animated CAPTCHAs not designed with this principle in mind can be easily be broken using simple techniques to extract individual characters from the animation frames. We present our experimental results on attacking 13 existing animated CAPTCHAs.

eaches of the trust infrastructure. We had simplicity, flexibility, and scalability in mind, solving the problem within the context of the protocol (with the underlying goal of embedding the solution in the TLS layer) with minor field changes, minimal cryptographic additions, no interaction with other protocol layers, and no added trusted parties.
