....to the OMAC algorithm as it was originally presented, changing one of its two constants. Speci cally, the constant 4 at line 40 was the constant 1=2 (the multiplicative inverse of 2) in the original de nition of OMAC [9] The OMAC authors indicate that they will promulgate this modi cation [10], which slightly simpli es implementations. 3 EAX Goals We wanted a block cipher based, nonce using AEAD scheme. It should provide both privacy, in the sense of indistinguishability from random bits, and integrity, in the sense of an adversary s inability to produce a new but valid (nonce, ....

....been followed: the one is guaranteed to work, while the other one is likely to work. In the last approach it is possible that although a certain set of participants has a cardinality larger or equal to t, they will not be able to perform the threshold computation in (5) We refer the reader to [20, 1, 6, 49]. 4.4 Generalizations g is not homomorphic What if the function g is not homomorphic This problem in its generality corresponds with the mental games problem [43, 4, 13] In its generality no practical solution has been proposed to address this problem. For some algorithms, such as DSS, a ....
....here, but that more randomness is required. A generalization The 2 out of l previous scheme is based on dlog 2 (l)e independent 2 out of 2 sharing schemes. The scheme in [6] satisfies a similar property. This scheme inspired Kurosawa and Stinson and they gave a generalization we now discuss [49]. Let A and A 0 be finite sets, B a subset of A, l = jAj and l 0 = jA 0 j and F be a set of functions from A to A 0 . We assume that l 0 l. A function f from A to A 0 is a perfect hash for B if f restricted to B is one to one. F is a Perfect Hash Family (l; l 0 ; t) if for all ....

....[28] 29] 30] Here we present a k out of l (k l) scheme which is based on perfect hash families. To illustrate our technique we first describe a simple 2out of l secret sharing scheme [26] Then we show how to get a k out of l scheme with k 2, using the KurosawaStinson interpretation [27], 30] of the scheme in [29] Let K( Delta) be an Abelian group and a 2 K the secret. We number the participants i from 0 to l Gamma 1 and represent i in binary, i.e. i corresponds to the bits (i 1 ; i dlog 2 (l)e ) For the shares, we choose dlog 2 (l)e independent uniformly random ....
