Defend3D引入了新的专利技术来对抗网络犯罪和IP盗窃

Remote 3D printing secured transmission serviceDefend3d已经引入了一项新的专利技术,以防止远程3D打印期间的网络犯罪和IP盗窃。

该技术基于单点击打印协议,使得无需文件传输的偏远位置的又一次繁殖零件的安全数字补给。取而代之的是,将连续的生产说明流向机器发出,并由六个级别的安全性(包括加密)确保。

Defend3D本质上可以实时将数字资产实时直播到3D打印机,而不是发送3D文件,而是提供数字资产,仅提供在立即删除它之前要访问的重要信息。

这项新技术已由英国的一个部门英国战略司令部测试国防部(MOD),Defend3D为数字制造提供了一个安全的平台,该平台将中央设计中心与多个部署的位置联系起来。

“我们评估这是一个改变游戏规则的能力,allowing us to overcome our current reticence of sending sensitive parts overseas, and allow us to send more parts wherever we wish in the world,” said an unnamed Lt. Col. from the MOD. “Being familiar with cutting edge 3D printing technologies, I believe this to be the only such system on offer.”

Cybersecurity risks in 3D printing

大量敏感数据流的存储和传输已在加法制造的数字化世界中变得司空见惯。该技术日益增加的工业化已经使3D打印机和制造设施变得越来越相关,尽管这很方便,但它也引起了网络安全漏洞的威胁。

main cybersecurity risks in 3D printing围绕IP盗窃和过程破坏。例如,可以黑客入侵基于云的文件共享系统,可能会破坏电子邮件服务器,并且可以使用3D扫描技术对实体3D打印零件进行反向设计。

为了证明灾难性过程如何破坏,研究人员来自本盖尔大学本·古里安大学,,,,University of South Alabama,,,,and新加坡技术大学以前有被黑客入侵用于制造无人机组件的3D打印机。该团队能够对无人机的3D打印螺旋桨进行不可检测的修改,从而使其超过质量保证,并损害了零件的完整性。

在美国国防部(国防部)之后,从辩护的角度来看,最近从辩护的角度强调了这种担忧first official additive manufacturing policycame under scrutiny from a report issued by the DoD Inspector General. The auditor claimed the DoD’s 3D printers could be容易受到敌对攻击者破坏的影响,,,,due to their access to the DoD’s wider information network.

Defend3D的专利技术

Defend3d’s new is designed to securely transmit remote 3D printing, CNC machining, laser cutting, bioprinting, and other digital manufacturing data with its One-Click-Print capability, achieved through its patented security protocol, the Virtual Inventory Communications Interface (VICI).

VICI消除了对文件传输的需求,可以通过发出由六个级别的安全性确保的复制指令来使远程零件的安全数字复制零件的安全补给。通过界面,记录了所有制造作业,以提供整个数字供应链中的审核步道。可以设置诸如机器设置和材料类型之类的变量,以确保满足制造和质量标准。

从本质上讲,Defend3D的VICI确保端到端加密使组织能够将其当地的设计存储在其家庭服务器上,同时允许他们使用虚拟库存在偏远位置制造零件。该公司正在为希望保护其IP并防止网络攻击的军事,航空航天,国防部或能源公司和组织提供努力,同时仍然能够从世界任何地方传递3D印刷零件。

用mod测试

随着国防部门内部采用3D打印的增加,网络安全脆弱性对IP和Process Sabotage的威胁是真正的。由于许多军事数字资产过于敏感而无法在外部共享,因此已经出现了不需要所有者向外部制造商发送数字印刷文件的安全协议。据报道,Defend3D的VICI协议实现了这一目标,并为国防和工业的共同努力铺平了道路,而不会损害敏感数据的传输。

VICI has been tested by the MOD’s UK Strategic Command through the development of a secure digital manufacturing platform that links up a central design hub in a secure facility, with multiple deployed locations that do not have engineering specialists.

该技术已与Microsoft Azure Cloud为了使从国防部总部到向前部署的地点的士兵跨越的服务和域名跨越的服务和域名共享。Defend3D的技术也得到了Azure Remote渲染的支持,以提供人工智能(AI)基于3D打印机远程管理和监视功能。

During testing, the 3D printed products delivered at the deployable end of the DEFEND3D network were compared with those printed at the base location to ensure part quality is maintained. Benchmark tests revealed that printing time and quality were not affected when using the DEFEND3D transmission service, even when compared to the print from an SD card.

一个Ultimaker 2+3D打印机用于生产3D打印的测试样品,其标准拉伸测试件用于连续性和简单性,分为三种不同的厚度,3毫米,5毫米和8毫米。

VICI has been designed with a low training burden, meaning that the 3D printer operator does not need to be an expert in 3D printing to be able to print the required files.

“向非熟练用户进行培训取得了成功,” MOD的机电一体化负责人说。“在30分钟内,他们能够从目录中选择一个文件,将其上传到打印队列,然后按照说明开始打印。这证明了VICI印刷软件是直观且易于操作,可以最大程度地减少培训负担。”

Defend3D与区块链

Defend3D还认为,其新技术可以克服blockchain technology,这是出现的另一种方法securing the digital threadof 3D printing processes, delivered by the likes ofSIMBA Chain

区块链是一个安全的分散数字分类帐,可在多台计算机上存储数据和记录称为“块”的信息。美国'最大的3D打印机网络使用区块链技术平台目前是作为一部分创建的自动化巷distributed manufacturing-focused钻石项目

According to the company, blockchains can prove inefficient in transporting the data of 3D files due to having ‘proof-of-work’, a measure to combat file manipulation, which slows down the creation of new blocks while the required proof-of-work is calculated and before they can be added to the chain.

相比之下,Defend3D的技术流3D打印数据直接实时地直接发送到3D打印机,并且仅提供当时必要的信息。此外,通过在其3D打印过程中利用区块链,OEM通常需要共享其IP或数字资产,并且整个3D文件仍然到达打印机,可能使其开放截距。

To mitigate this, DEFEND3D’s security protocol prevents file transfer while still providing authentication such as hashing algorithms to ensure the integrity of the data being transferred. The technology also has multiple mechanisms in place to detect any “sniffing” activity or an imminent attack, and will shut down the printing job if such attacks are detected.
