Unique transaction security for financial and digital assets applications.
Securosys Hardware Security Modules (HSM) are not only optimized for the physical protection of private key material like most legacy HSMs; Securosys HSMs provide control of the keys usage with specific and sophisticated authorizations, which is essential for the security of modern financial applications.
Todays' financial and digital assets applications require the possibility of implementing fine-grained policies to allow for different actions on transactions to be done. With keys that are based on groups, quorums and maybe also time restrictions - or any combination of them. Securosys Smart Key Attributes (SKA) helps enforce such policies and rules.
To make the implementation of SKA's easier, the Securosys Transaction Security Broker provides a REST API and internal state management. It is a standalone engine, which connects to an external database instance and integrates the SKA-enabled Securosys HSM - and is thus uncritical for security, since all security relevant operations are carried out in the HSM.
The TSB integrated with the SKA-enabled Securosys HSM provides the most granular control over key actions and operations.
It allows the finance organization to set highly customizable policies for authorizing operations and transactions, blocking or unblocking the keys, and changing the policies themselves.
The use-cases range from n to m quorums, time-locks that allow systems to trigger alarms and block key operations, to time-outs that ensure that suspended transaction requests cannot be misused in the future, and any combinations of these.
Timestamps transaction request, determines required approvals, collects approvals, sends approvals to HSM for signature, delivers back signed transaction.
