cpSecY
cpSecY is a security protocol and framework designed to provide confidentiality, integrity, and authenticity across distributed systems. It aims to unify transport-layer security with data-at-rest protections into a single coherent model, suitable for client-server, microservices, and IoT environments. The design emphasizes modularity, formal verifiability, and interoperability with existing cryptographic standards.
The cpSecY reference architecture comprises a Core Protocol, a Key Management Service, a Policy and Access
Security properties include mutual authentication, forward secrecy, data integrity, and optional post-quantum algorithm support. It supports
Protocol flow typically involves mutual credential verification, negotiation of cryptographic suites, ephemeral key exchange, and establishment
Adoption and status: cpSecY is described in academic work and has inspired industry prototypes but has not
