第5章Hash函数与消息认证习题 1.什么是篡改检测码(MDC)?MDC是如何产生和怎样使用的?消息认证码(MAC)是MDC吗?(消息的)数字签名是MDC吗? 2.什么是随机预言机?随机预言机存在吗?随机预言机的行为是如何逼近现实世界的?

Domains represent 3D regions where governing equations are solved Domains can be comprised of more than one solid joined together Domains can also contain internal 3D regions Cutouts- solid obstacles to flow Sub -domains- Fluid sub-domains: volumetric sources/sinks of mass. heat

Create a solid which defines the region of interest. Define the fluid domain in terms of flow region, physical models, and fluid properties. Apply boundary conditions to fluid domain surfaces. Specify an initial guess/condition for the simulation

一、 Hash函数概述 二、 Hash函数MD5 三、安全Hash算法SHA 四、基于分组密码与离散对数的Hash函数 五、消息认证

Boundary conditions are required to set on all external domain boundaries Initial values/guess are required to set for all calculations Boundary conditions and initial values/guess can be either constants or expressions

Eco514 Game Theory Lecture 5: Games with Payoff Uncertainty(2) Marciano Siniscalchi September 30, 1999 Introduction This lecture continues our analysis of games with payoff uncertainty. The three main objec- tives are: (1) to illustrate the flexibility of the Harsanyi framework (or our version thereof);

Chapter 5 Dynamic Contracting 5.1 Incomplete contracts In our earlier treatment of contracting problems, we assumed that the in- centive problem was generated by asymmetric information, either a problem of moral hazard(hidden actions)or adverse selection(hidden information) The incomplete contracts approach eschews asymmetric information because of its intractability and instead focuses on environments in which informa- tion is observable but not verifiable
