Sepior’s threshold cryptographic systems use multiparty computation (MPC) to provide industry leading key management services with greater security, resilience, performance and scale - enabling application and service providers, their partners and customers to Transact with Trust!

  • Trust in Confidentiality

  • Trust in Integrity

  • Trust in Availability

Providing Advanced Security For Distributed Applications

 
 

Blockchain Services

Sepior™ Threshold KMS delivers compelling off-chain key management solutions to control the privacy and security of data and transactions on permissioned blockchains. Works with any blockchain technology platform for maximum flexibility, scale and interoperability!

Digital Asset Services

Sepior™ ThresholdSig provides industry leading security for digital asset wallets and exchanges. It provides the industry’s most secure multiparty approval with substantial security and operational benefits over MultiSig.

Cloud-Based Services

Sepior™ KMaaS is a native cloud-based key management as a service which is available to cloud service providers as a white labeled service. With support for BYOK across multi-cloud networks, it’s a compelling alternative to traditional key management services.

 

Are Your Blockchain, Digital Asset, And Cloud Services Secure?

Online systems such as private blockchains, digital asset exchange wallets, and conventional cloud services place critical data and assets in vulnerable environments. And it’s not just your data, increasingly your systems will host critical data for your partners and customers as well.

Encryption provides excellent data security. It’s virtually impossible for a hacker to break the code of today’s advanced encryption algorithms. The far greater risk is that someone steals the key used to encrypt and decrypt data, allowing them to fake your signature, or decrypt and steal digital assets.

Can all parties trust that the keys and therefore the digital assets under your control are secure?

 
 
 

Flawed Security Models Undermine Private Key Integrity

A fundamental problem with conventional key management models is the assumption of an ideal environment. It’s assumed that cryptographic computations will be executed without interference, and the keys used for cryptographic functions are available and kept secure.

For these systems it’s assumed that no side channels exist to leak secret keys, and no attacks will alter computations to corrupt the keys or render systems unavailable. But in the real world, those risks exist.

Will your key management system protect data and digital assets in the presence of real world risks?

Threshold Cryptography For Sustainable Security In The Real World

Hackers or rogue users will, on occasion, violate one or more of the security defenses used by your company, a partner, or a customer accessing your online services or systems. When these events occur, you can trust that Sepior’s threshold cryptographic solutions will protect your private keys which protect your assets with the highest level of security available, and with dramatically lower cost and complexity than conventional key management solutions.

Sepior is setting new benchmarks for online security with threshold cryptographic systems that remain available and fully functioning in real world conditions. This exciting new field of cryptography incorporates MPC to eliminate the dependency on any single device or a single trusted third party.

Sepior’s threshold cryptography establishes trust through consensus across multiple parties, enabling trust even if one, or possibly more, of the participants is compromised. The result is cryptographic key management with a higher level of confidentiality, integrity, and availability than is practically achievable with conventional alternatives – especially when considering the risks present in the real world.

 
 
 

Real World Apps Require Real World Key Management Security

Every online system hosting confidential data or digital wallet services should employ effective security and proper key management. For many applications, a basic level of security is sufficient. However for others applications, secure transaction signing, data confidentiality, integrity, and availability are mission critical and thus require advanced levels of key management security. Some examples include: 

Cryptocurrency Exchanges and Other Providers of Digital Asset Wallets

  • Cryptocurrency is a hot and rapidly evolving market. The stakes for continuously secure wallet services are paramount, however bitcoin thefts totaling billions of dollars have occurred across multiple exchanges. In most cases, these losses are attributed at least in part to insufficient key management for wallet security. Find out how Sepior’s Threshold Signature (ThresholdSig) wallet security sets new industry benchmarks for digital asset wallet security.

Private and Permission Based Blockchains Facilitating Smart Contracts

  • Blockchain technologies are rapidly moving toward more conventional business use cases, and will increasingly incorporate smart contracts to automate the recording of business activities with indelible ledgers. Find out how Sepior’s Threshold Key Management System (Threshold KMS) blockchain security is unleashing the potential of blockchain with more granular and flexible control over who has visibility to specific fields of information on the chain.

Cloud Service Providers Offering Fully Managed KMaaS and Multi-Cloud BYOK

  • CSPs are under increasing pressure to provide affordable, scalable, and effective key management services to equip subscribers with the level of control they desire for managing security of their cloud assets.  Find out how Sepior’s Threshold Key Management as a Service (Threshold KMaaS) and Threshold Bring Your Own Key (Threshold BYOK) white label services can give your cloud-hosted service a competitive edge.
