Simultaneous hashing of multiple messages
We describe a method for efficiently hashing multiple messages of different lengths. Such computations occur in various scenarios, and one of them is when an operating system checks the integrity of its components during boot time. These tasks can gain performance by parallelizing the computations and using SIMD architectures. For such scenarios, we compare the performance of a new 4-buffers SH...
متن کاملSimultaneous Messages vs. Communication
In the multiparty communication game introduced by Chandra, Furst, and Lipton CFL] (1983), k players wish to evaluate collaboratively a function f (x0; : : : ; xk?1) for which player i sees all inputs except xi: The players have unlimited computational power. The objective is to minimize the amount of communication. We consider a restricted version of the multiparty communication game which we ...
متن کاملCommunication Complexity of Simultaneous Messages
In the multiparty communication game (CFL-game) of Chandra, Furst, and Lipton (Proc. 15th ACM STOC, 1983, 94–99) k players collaboratively evaluate a function f(x0, . . . , xk−1) in which player i knows all inputs except xi. The players have unlimited computational power. The objective is to minimize communication. In this paper, we study the Simultaneous Messages (SM) model of multiparty commu...
متن کاملUniversal Hashing and Multiple Authentication
In this paper, we study unconditionally secure codes that provide authentication without secrecy. Our point of view is the univcrsal hashing approach pioneered by Wegman and Carter in 1981. We first compare several recent universal-hashing based constructions for mthenticatmion codes. Then we gencralize the theory of universal hashing in order t,o accommodate the situation where we would like t...
متن کاملSimultaneous modeling of multiple recurrences in breast cancer patients
Introduction: Breast cancer is one of the most common recurrence cancers among women. There are several factors that can affect multiple recurrence of this disease. On the other hand, simultaneous examination of the types of relapses will make the results more accurate. The purpose of this study was to use a joint frailty model to model multiple recurrences of breast cancer patients. Materials ...
