Gary M. Landsberg,Rachel Malamedel repetitions. This result holds both in the plain model (without any set-up) and in the Bare Public-Key Model (where the prover and the verifier have registered public keys). We complement this result by showing the existence of a public-coin black-box zero-knowledge proof that remains secure unde

Canine and Feline Skin Cytologyld, we give a sub-linear size zero-knowledge argument that one committed matrix is the product of two other committed matrices. We also offer a sub-linear size zero-knowledge argument for a committed matrix being equal to the Hadamard product of two other committed matrices. Armed with these tools w

Curing with ultraviolet radiation,AES-256 .-multicollisions can be constructed in time .·2. and with negligible memory, while we prove that the same task for an ideal cipher of the same block size would require at least . time. Using similar approach and with the same complexity we can also construct .-pseudo collisions for AES-256

Curing with ultraviolet radiation,cret 8 to 8 bit S-box. We show that if the attacker is allowed to choose the key, the S-box can be recovered in 2. C2 encryptions. Attacking the 56 bit key for a known S-box can be done in complexity 2.. Finally, a C2 implementation with a 8 to 8 bit secret S-box (equivalent to 2048 secret bits) and
