              加密狗是怎么做的?

              2021-08-16 17:28:19 來源:http://www.eboudy.com/ 53

              加密狗,也稱作加密鎖,是一種用在計算機、智能硬件設備、工控機、云端系統等軟硬件加密產品。軟件開發商通過加密狗管理軟件的授權,防止非授權使用或者抵御盜版威脅,保護源代碼及算法。廣義的加密狗是一整套軟件加密方案,針對不同軟件的使用量、經濟價值、面臨破解的壓力以及軟件使用環境等要求綜合因素的考量下,設計從軟硬件識別、數據通信、授權管理、分發模式和物理硬件要求等環節的完整軟件加密解決方案。
              Encryption dog, also known as encryption lock, is a software and hardware encryption product used in computers, intelligent hardware devices, industrial computers, cloud systems and so on. Software developers manage software authorization through dongles, prevent unauthorized use or resist piracy threats, and protect source code and algorithms. The generalized dongle is a complete set of software encryption scheme. Considering the usage, economic value, cracking pressure and software use environment of different software, a complete software encryption solution is designed from the aspects of software and hardware identification, data communication, authorization management, distribution mode and physical hardware requirements.
              好的軟件加密解決方案必須包括軟件保護涉及的各個方面,如:安全、易用、耐用、兼容性好、跨平臺、豐富的授權管理功能等。而安全則是一個木桶效應,如果僅采用軟件加殼工具或僅采用API加密,或僅考慮智能卡加密狗,這些方法都存在短板,會為破解者所利用并進行攻擊。
              A good software encryption solution must include all aspects involved in software protection, such as security, ease of use, durability, good compatibility, cross platform, rich authorization management functions, etc. Security is a barrel effect. If only software shelling tools or API encryption are used, or only smart card dongle is considered, these methods have shortcomings and will be used and attacked by crackers.
              除了面臨國內外軟件巨頭的擠壓之外,同時面臨著盜版對軟件發展的巨大沖擊。并且由于中國軟件企業的發展正由之前的軟件模仿向創新、創意發展,因此軟件加密已成為中國軟件企業乃至硬件設備商的重中之重。加密狗可以簡單分為硬件、軟件形式的加密安全方案:

              Chinese original software enterprises are surviving in the cracks. In addition to being squeezed by domestic and foreign software giants, they are also facing the great impact of piracy on software development. And because the development of Chinese software enterprises is changing from software imitation to innovation and creativity, software encryption has become the top priority of Chinese software enterprises and even hardware equipment manufacturers. The dongle can be simply divided into hardware and software encryption security schemes:

              首先需要明確的是軟件加密是完全站在軟件開發商角度出發的,它強調的是軟件保護和不被盜版,具體包括源代碼不被反編譯、軟件不被隨意篡改、軟件不被逆向工程,同時也包括軟件授權不被非法拷貝、不被篡改。也即從側面反映軟件加密是一個全面的概念,不是用某一種技巧或某一種方法達到真正的安全防護效果。
              First of all, it needs to be clear that software encryption is completely from the perspective of software developers. It emphasizes software protection and non piracy, including that the source code is not decompiled, the software is not tampered with at will, the software is not reverse engineered, and the software authorization is not illegally copied or tampered with. That is, software encryption is a comprehensive concept from the side, not to achieve the real security protection effect with a certain skill or method.
              市面上的純硬件加密狗產品的價格不等,從低價品到高端加密產品種類繁多,其產品特點即是加密狗廠商提供硬件及接口函數給軟件開發商,軟件調用硬件,達到表面上看沒有加密狗就不能訪問軟件的效果,實現軟件加密。采用此類產品,軟件開發商需要花費大量的人力、物力、財力及大量時間去做軟件加密方案,如果軟件開發商沒有開發實力則加密后的軟件極易被破解。
              The prices of pure hardware encryption dog products on the market vary from low-cost products to high-end encryption products. Its product feature is that the encryption dog manufacturer provides hardware and interface functions to software developers, and the software calls the hardware, so as to achieve the effect that the software can not be accessed without the encryption dog on the surface, and realize software encryption. Using such products, software developers need to spend a lot of manpower, material resources, financial resources and a lot of time to do software encryption schemes. If the software developers do not have the development strength, the encrypted software is very easy to be cracked.

              ?因此純硬件加密狗廠商的技術服務能力就顯得尤為重要,一方面為軟件開發者節省時間和成本,另一方面優質的技術服務意味著高速的售后響應,杜絕用戶端因加密狗出現失效而造成損失的問題。從這一層面來看,純硬件加密狗的價值絕不僅僅體現在其硬件售價,更要看加密狗廠商的服務,高端加密狗產品更是如此。
              ? Therefore, the technical service capability of pure hardware dongle manufacturers is particularly important. On the one hand, it saves time and cost for software developers. On the other hand, high-quality technical service means high-speed after-sales response, so as to eliminate the loss of users due to the failure of dongles. From this perspective, the value of pure hardware dongle is not only reflected in its hardware price, but also depends on the services of dongle manufacturers, especially high-end dongle products.
