网上发布共享软件的制作(下)

三、注册码 当用户注册成功后,注册码就被写到共享软件的相应位置。这时共享软件必须对用户注册码进行实时检测与判断,才能实现注册限制功能。这时要求共享软件必须内部取得注册源数据,并利用注册机中相同的算法产生内部注册码。这就要求共享软件直接读取ROM BIOS的注册源信息,并在共享软件中需要限制的功能处增加注册码检测判断功能,这需要根据共享软件的实际需要、软件大小和实现的难易     

利用硬盘序列号实现对VFP软件注册的解决方案

现在网上一些共享软件通过采用注册码验证机制来实现对软件部分功能的限制使用,而注册码是根据用户计算机中的唯一硬件参数来生成的,即一台计算机对应唯一的一个注册码,这样可以防止注册码的盗用问题。本文详细阐述了在VFP应用软件中通过读取用户计算机的硬盘序列号,生成注册码,从而实现对软件进行注册的解决方法。     

共享软件加密的一些误区

共享软件从出现的那一天起就深受破解者(Cracker)的"喜爱",因为相对于防范较为严密或使用硬件加密的商业软件来说,共享软件是比较容易破解的.虽然许多共享软件的作者也采用了时间限制或注册码校验等方法保护自己的软件,但是多数共享软件的作者对软件加密与解密技术不了解,对加密方法的应用和代码编写过程中存在很多漏洞,从而使看似很可靠的加密方法形同虚设.软件加密与解密之争,道高一尺魔高一丈,但是最终往往不是技术致胜,而是心态致胜,本文以软件破解者的心态分析了一些软件作者常犯的错误,并提出了相应的防范措施.

Tailoring by integration of domain-specific components: the case of a document search tool

In this paper we describe the evolutionary design and implementation of a search tool for files in shared workspaces used within an off-the-shelf groupware product. The design is based on the assumption that a useful generic search tool must be highly tailorable, which is achieved by applying an innovative software architecture allowing the assembly of components during runtime. In order to understand people's searching methods in shared workspaces and to support the design, we employed interviews and workshops with users as well as a field test to understand the users' needs. During the design process we developed a series of prototypes that were then evaluated by office workers. Consequently, the process described and the lessons learned extend from searching in files as a case via tailorability of software as an answer to the resulting requirements to component architecture as a way to implement this tailorability. The results derived from the treatment of these interrelated aspects constitute the core and value of this paper.

A family of languages for architecture constraint specification

During software development, architecture decisions should be documented so that quality attributes guaranteed by these decisions and required in the software specification could be persisted. An important part of these architectural decisions is often formalized using constraint languages which differ from one stage to another in the development process. In this paper, we present a family of architectural constraint languages, called ACL. Each member of this family, called a profile, can be used to formalize architectural decisions at a given stage of the development process. An ACL profile is composed of a core constraint language, which is shared with the other profiles, and a MOF architecture metamodel. In addition to this family of languages, this paper introduces a transformation-based interpretation method of profiles and its associated tool.

Maintainable systems with a business object approach

The concept of Business Objects (BOs) has been recently promoted as a new way of exploiting object‐orientation for achieving large‐grain reuse. In this paper, we address the issue of how to effectively re‐engineer business software applications using BOs as a reuse technique. To this end, we first identify the reuse features of business objects and then compare them with other reuse techniques. In addition, we show that software re‐engineering can be more economical when business objects are used. Our work also provides guidance on how to develop and use a Business Object Architecture (BOA), which is shared by a group of interrelated and interdependent software applications. We argue that such architecture allows for more efficient reuse and better maintainability and it is illustrated by means of a case study in a realistic manufacturing environment.     

基于逻辑的软件体系结构共享注入点检测方法

已有的方面交互分析方法大多未考虑共享注入点的检测,从而影响了它们的实际应用。针对这一问题,基于面向方面软件体系结构描述语言AC2-ADL,提出了一种基于逻辑的软件体系结构层共享注入点检测方法。首先基于一阶逻辑,给出了软件体系结构层注入点和切点指示器（pointcut designator,PCD）的形式化描述方法。在此基础上,应用一阶逻辑公式的合一思想,提出了软件体系结构层共享注入点的相关定义及定理,并进一步设计出软件体系结构层共享注入点的检测算法。该研究成果可为在其他面向方面软件体系结构描述语言定义的体系结构中检测共享注入点提供借鉴和参考。
