1. KMSCHAIN: DECENTRALIZED KEY MANAGEMENT SOLUTION
Data is a Core Resource We live in a data-centric world, where data is the cornerstone of business infrastructures and driving force of social-economic relationships 2.5 2.5 qu quintilli lion byt ytes s of of da data is s cr created per per da day 90% 90% of of da data ha have be been cr created in las ast two yea ears Em Emergence of of au audit an and com ompli liance req equir irements s (GD (GDPR, , HI HIPAA, CJI JIS, , FER FERPA, , PC PCI, I, IT ITAR, etc.) 4
Encryption as a way to Protect Data Encryption is a robust approach of protecting data from breaches and leaks.

What are Alternatives of Key Management? Amazon, Google, Microsoft, Alibaba provide Key Management as a Service for addressing this technical challenge. But these services have single point of failure 1. Service providers get access and manage all user keys. 2. Centralized Services with an undue trust put on the service provider can not serve decentralized applications 8
Combining the Best of Both Words We provide flexible encryption and data management technology which does not compromise the data security via introducing single point of failure Legacy Encryption Federated Key Method Management ain Schai ✓ Secur curit ity y KMSc ✓ Sca calabi ability lity KM ✓ Privac vacy ✓ Convin vinence ence 9

Decentralized Privacy Layer KMSchain enables to build decentralized, zero-knowledge Key Management Services to solve a significant market need enabling DApps and other data critical applications to integrate data encryption and KMS technologies without compromising decentralization. Re Re-encry ryption Key Re-encryption key are split into multiple re- encryption shares. We leverage cutting-edge cryptography techniques and blockchain technology to decentralize our service into multiple standalone KMS Services (nodes)

Add data encryption and cryptographic trust management into your app with just a few lines of code. Perform Re-Encryption for the given ciphertext and Generate and Manage User's Public and Private keys. the re-encryption key Enable users to generate Re-Encryption keys Decrypt both the original or transformed ciphertexts in for their peers. order to reveal the encapsulated symmetric encryption key Encapsulate a symmetric encryption key via given Public Key (similar to Diffie-Hellman Key Exchange) 20
1.3 USE CASES OF THE TECHNOLOGY
Big Data Systems Development of the big data systems which enables secure transfer of data, development of collaborative data lakes, monetization of the enterprise data. 22
Data Marketplaces (Financial, Insurance, etc.) KMSChain provides robust infrastructure for the development of decentralized data marketplaces. Anonymity ymity and Privac ivacy protectio ection Decent entraliz alizati ation on Trans nspar parency ency Control ol 23
KYC, KYT, Digital Identity Systems Secure and flexible control over digital IDs, streamlining travel, KYC, insurance claims, and more. 24
Social Networks, Secure Chat Rooms Via KMSchain users can create very secure social groups by assigning different attributes and keys to their social contacts, and then encrypt data such that only particular users with desired set of attributes can decrypt it. 25
Role based Data Management and Access Control If there are different classes of nodes in the network (master nodes, service providers, Oracles, etc.) our technology can be applied to segregate the permission levels of these users, also enabling dynamic self-management. 26
