Cryptographic Testing
Our Cryptographic Security Testing (CST) laboratory, accredited by the National Voluntary Laboratory Accreditation Program under Lab Code #200658-0 (https://www.nist.gov/nvlap), performs testing of cryptographic modules and algorithms as well as entropy sources.
FIPS 140-3 Testing
atsec is ready to partner with you to help you understand the requirements of the standard, assess your product’s readiness for FIPS 140-3 validation, and perform the conformance testing that will earn certification for your cryptographic product.
Cryptographic Algorithm Testing
Testing whether cryptographic algorithms are implemented correctly is a prerequisite for FIPS 140-3 cryptographic module testing and NIAP Common Criteria evaluations. atsec US offers the algorithm testing specified under the NIST Cryptographic Algorithm Validation Program (CAVP).
Entropy Source Assessment
The CMVP requires that all FIPS 140-3 module validation submissions include documented conformance to SP 800-90B when applicable. atsec offers entropy source analysis for ESV Certificates to meet the CMVP requirements.
Your Partner for Cryptographic Security Testing
atsec information security provides FIPS 140-3 testing services to review requirements, assess product readiness, and perform conformance testing. We also offer Cryptographic Algorithm Testing (CAVP) and Entropy Source Validation (ESV) to ensure proper implementation and compliance with standards.
