We Solve Problems
Stealth Software Technologies specializes in cutting-edge privacy enhancing technologies (PETs). Through our performance on competitive government programs (including Government funding from DARPA, IARPA, NSF, and NIST), our team of world-class researchers and engineers has invented many of the security tools that shape today’s cryptographic landscape and tomorrow’s PET solutions.
Bringing results in cryptography to life
Stealth approaches data privacy and security challenges by translating theoretical advances in cryptography into real-world software implementations. Our extensive background in cryptographic research and a deep bench of leading academic consultants enable us to build solutions based on the latest theoretical breakthroughs, and we use our internal expertise in software engineering to produce practical, usable implementations.
We develop privacy-enhancing technologies and support research advances in the areas of secure multiparty computation (for example to perform secure federated learning), zero-knowledge proofs, zero-trust networking, searchable encryption, secure cloud storage, authentication, secure blockchain (for example for supply-chain management), and secure and resilient communication. These technologies can apply to, and have been tested in, a wide variety of settings including protecting confidential enterprise information, ensuring robust mobile and Internet-of-Things networks, promoting transparency and validation for complex machine learning tasks, and enhancing secrecy and resilience on the battlefield edge.
Research areas
Stealth’s significant contribution to the fields of cryptography and cybersecurity stems from the work of co-founder Prof. Rafail Ostrovsky, who has played a leading role in inventing many foundational aspects of modern cryptography, including searchable encryption, private information retrieval, deriving keys from fuzzy biometrics, oblivious RAM, and deniable encryption technologies. Since our founding, we have been driven by this spirit of innovation, as we continue to lead the way in generating new ideas and solutions that advance the state of the art in privacy-enhancing technologies.
Building the next generation of PETs
Stealth has developed numerous solutions while performing under dozens of grants and contracts from government and private organizations, including:
- Secure Analytics Engine: Enables computation on encrypted data, allowing multiple organizations to extract analytic insights from their aggregated data without sharing data sets, and without decrypting data.
- Searchable Encryption: Enables cloud-based or other remote data hosts to support database search on encrypted records.
- Anonymous Communication: Enables large-scale secure and anonymous messaging across adversarially controlled networks, hiding messages and sender-receiver connections from the network itself.
- Privacy-Enhanced Blockchain: Supports standard blockchain features of immutability and verifiability, but with optional on-chain storage of private, encrypted data and accompanying tools for zero-knowledge auditing and privileged access.
Experts in privacy-enhancing technologies
Our team consists of world-class professors, researchers, and developers who have pioneered many of the tools that shape today’s cryptographic landscape. We have hundreds of publications in leading journals, conferences, and books, and we have been awarded numerous U.S. federal grants and contracts to develop cutting-edge secure technologies for a wide range of applications. Since our founding, we have amassed an extensive collection of cryptographic solutions and tools, and over a decade of experience in a fast-moving field. The resulting depth and breadth of our toolkit allows Stealth to satisfy a broad range of our customer’s security and privacy requirements. As performers on Government programs, our designs and implementations have been tested in a wide range of settings by organizations such as MIT Lincoln Laboratory, RAND Corporation, and JHU Applied Physics Lab.
