Cryptanalyses of Narrow-Pipe Mode of Operation in AURORA-512 Hash Functione complexity is approximately 2. AURORA-512 operations, and 2.×512 bits of memory is required. Our key-recovery attack on HMAC-AURORA-512, which uses 512-bit secret keys, requires 2. queries, 2. off-line AURORA-512 operations, and a negligible amount of memory. The universal forgery on HMAC-AURORA-3

More on Key Wrappinghich roughly formalizes “the strongest security that one can get without randomness.” Although DAE is weaker than full blown authenticated encryption, it seems to suffice for the case of key wrapping (since keys are random and therefore the encryption itself can be deterministic).

More on the Security of Linear RFID Authentication Protocolsin this paper. We present several active and passive attacks against (.,.,.)-protocols and propose (.,.,.).-protocols which we can prove to be secure against certain types of active attacks. We obtain some evidence that the security of (.,.,.)-protocols can be reduced to the hardness of the . (LULS)

The issues addressed are somewhat technical, but they are also both instructive and necessary for securing the desired results. The second example utilizes empirical process results fo
