供应链数字中心如何推动疫情后的供应链弹性

Cheryl Wiebe

DOMAIN是指我们在某些数据区域周围绘制线条的能力,因为它们彼此之间具有很强的亲和力,例如销售或支持(请参阅下面的Thoughtworks中的图表)。数据亲和力分组功能强大,因为它允许组织分离出一部分数据,并将其置于一个小组主题专家的管理和责任之下,他们出于自身的利益可以很好地策划和管理这些数据。

正如现在正在讨论的那样,围绕数据网格的所有炒作(以及数据湖、数据湖等),让我们不要过多地陷入这些嗡嗡作响的话题中。基于Rajnesh的“回归基础”博客文章,我们如何管理云架构的旅程,同时支持企业、创新和特定领域的中心的概念。我们所说的“基础知识”是什么意思?它带来了数据集成和重用的核心原则,其基础设施使我们能够实现一组特定于领域的数据产品,利用连接的多云数据和分析平台(如Teradata Vantage)的共享基础架构,以封装和构建特定领域的知识和模型的方式,使数据消费者受益。要了解更多信息,这篇博客文章将详细介绍现代云平台需要考虑的六个关键功能。集成数据管理是这六项功能之一,它直接影响敏捷性、响应能力和安全性。
现在,回到供应链领域。供应链是一个可以从这些最新发展以及我们带来的数十年供应链数据经验中受益的领域。我建议它可以作为特定领域的数字中心来实现。碰巧的是,通过这样做,我们还可以实现未来数字供应链中的关键理想属性之一:弹性。

  • 频繁的重新配置:关闭和开放新轨道、新的运营中心,新的供应商;增加新的产品线、新的配送中心。
  • 感知行为变化:随着供应链交货时间、可变性和服务水平承诺的变化,监控和更改供应链计划参数。
  • 了解新的和不断变化的成本和替代方案:中断的影响和合同承诺,如费用、罚款和服务成本,以及这如何影响替代方案的选择。
  • 政策和治理发生变化,因为组织了解到从替代方案中选择哪些效果最好和最差,以及哪些决策可以自主做出。

摘要: 在基于云计算的存储与删除服务中,由于外包数据所有权和管理分离,现有的逻辑删除机制使云上的数据很容易暴露给未经授权的用户,甚至云服务器可能未遵循用户要求删除相应数据。为此,该文提出一种细粒度的安全云端数据存储与删除方案。基于椭圆曲线构造了基于密文策略的属性基加密以实现外包数据细粒度访问控制,应用区块链实现可公开验证的安全数据删除。该文方案具有责任可追踪性以及两方删除与可验证性等特性。理论分析与实验结果表明该文方案具有较好的安全性和较高的性能,能够满足云数据共享与安全删除的需求。

Abstract: In the storage and deletion service provided by cloud 云交所云链(Cloud Chain) computing, due to the separation of outsourced data ownership and management, the cloud server may not follow the user’s request to delete the corresponding data, and the outsourced data can be easily exposed to unauthorized users due to 云交所云链(Cloud Chain) the widely-adopted logical deletion. Therefore, 云交所云链(Cloud Chain) an efficient and secure cloud data storage and deletion scheme is proposed. Firstly, an attribute-based encryption based on ciphertext policy is constructed based on elliptic curves to achieve fine-grained access control. Secondly, publicly verifiable data deletion is realized by using blockchain. The proposed scheme has the characteristics of responsibility traceability, two-party deletion and verifiability. Theoretical analysis and experimental results show that the presented scheme has more desirable security and performance, and can meet the needs of cloud data sharing and secure deletion.
