Thomas Zakrzewski (Tom Z.) is a Founder and Managing Partner at EgisData; Former Distinguished Engineer and Head of Blockchain at S&P Global Ratings. He developed products protecting private and confidential information using advanced cryptography and blockchain. He co-authored a patent for a solution addressing issues with data privacy, data localization, and preparedness for post-quantum ciphers using advanced cryptography and blockchain. Tom has over 25 years of IT experience in Financials, Software Engineering, Telecom, e-Commerce, Distribution & Logistics, and Healthcare. He holds a Bachelor’s Degree in Computer Science and Mathematics from Montclair State University and a Master’s Degree in Predictive Analytics from Northwestern University. Throughout his career, he held numerous positions ranging from developer to architect, to CIO. Currently, he serves on the Advisory Boards for the New Jersey Institute of Technology (NJIT) and Montclair State University, as well as the Big Data Certification Program at Rutgers University. Tom is also a Visiting Technologist Fellow at the National Security Institute (NSI). Tom is a frequent speaker at conferences discussing blockchain security, crypto assets, and quantitative models. Speech Overview: Encryption is the most effective method to protect information. Yet, due to the high cost of encryption products, maintenance, and implementation, encryption is only utilized by the Fortune 1000 companies. EgisData has developed the product Encryption as a Service, encompassing the integration of secured and scalable Key Management and fine-grained control access to resources. In this session, attendees will learn about today’s challenges to manage scalable blockchain deployments, Digital Identities management, and protection of private and confidential information.

BLOCKCHAIN
The only mistake in life is the
lesson not learned.

What is missing in
blockchain to achieve
scalability, interoperability,
and confidentiality

BLOCKCHAIN PRINCIPLES

nonrepudiation –
cannot deny authenticity
transparency – ‘everyone’
sees the same state
permanency – cannot
change the state
resiliency – state is
replicated to other instances

THE MAIN THING …
7
➢Keys Management
➢Identity and Access Management
➢Legacy Systems (and processes)
The main thing is to
keep the main thing the
main thing.
~ Stephen Covey

8. TomZ.,
THE MAIN THING …
8
➢Keys Management
▪ Private and public keys are fundamental artifacts for blockchain, and
proper management must be part of the blockchain eco system
▪ Use of Keys
▪ Signing transactions
▪ Encryption
▪ Standards for keys storage and access: PKCS#11, and PKCS#12
▪ HSM
▪ MPC based virtual Keys Vaults
▪ Other open source virtual key storage

9. TomZ.,
THE MAIN THING …
9
➢Identity and Access Management
▪ Identity is an information about an entity interacting with a system.
▪ Identity authentication is a process determining authenticity of the
identity
▪ Authorization is a process of authorizing Identity to use resources through
an Access Management
▪ Role Based – RBAC (coarse grained)
▪ Attribute Based – ABAC (fine grained based on policies)
▪ EgisData developed NIST recommended ABAC policy engine and
integrated with Key Vaults providers
▪ ABAC is a fundamental component for Zero Trust environment

10. TomZ.,
THE MAIN THING …
10
➢Legacy Systems (and processes)
▪ Blockchain relays – off-chain services
▪ Challenges remains to match identities and authorizations between
blockchains and legacy systems

Now this is not the end. It is not
even the beginning of the end. But
it is perhaps, the end of the
beginning.
