Post-Quantum Cryptography

I-AM is a cryptographic authentication technology from Fortytwo Labs that provides mutual authentication between two or more communicating parties. It is designed as an alternative to traditional asymmetric cryptography (2-way-SSL) approaches, offering a quantum-safe method for parties to positively and provably authenticate each other. The technology is delivered through an SDK that developers integrate into applications, web applications, mobile apps, or APIs. An administrative portal is used to set up and distribute pre-shared information out-of-band to SDK consumers, with identity onboarding supported through RPA, sync, or manual entry via the portal. When a resource is requested, the SDK performs mutual cryptographic authentication between parties, producing a key exchange that can be used for further cryptographic services. The vendor positions I-AM as an identity-centric cryptographic services platform intended to address a broad range of security use cases beyond authentication alone. Key characteristics: - Mutual (not one-way) authentication between two or more parties - Quantum-safe cryptographic design - SDK-based integration for apps, web apps, and APIs - Administrative portal for setup and identity onboarding - Out-of-band distribution of pre-shared information - Produces a key exchange usable for other cryptographic services - Developer portal with documentation and sample integrations</description> <parameter name="summary">Quantum-safe SDK for mutual cryptographic authentication between apps, APIs, and users
