Abstract: We consider the use-case of Internet of Things ecosystems with an API-driven microservice architecture, where the need for accessing cryptographic functions is crucial. Devices communicate with a microservice backend, which in turn integrates to a secure key storage in order to compute digital signatures or message encryption. Access to a secure storage must be executed securely and naive approaches such as passwords or certificates are used in practice today, which still may be open to impersonation attacks. With the usage of efficient cryptographic accumulators we therefore propose a secure key access scheme with the microservices ecosystem in mind, and provide initial results from a proof-of-concept implementation in Java and jPBC, where we show a performance- and communication complexity analysis. Finally, we provide a security analysis of the scheme in the random oracle model.
