System and method for pre-shared key (psk) based selective encryption of partial sections of messages

Abstract

The method provides an automated and scalable system for the generation, distribution, management of symmetric pre-shared keys (PSKs) to applications executing on headless and mobile devices. It helps achieve device protection, application security, and data protection with data authenticity and confidentiality in intra-device, inter-device, device-to-edge, and device-to-cloud communications. It helps Transport Layer Security (TLS) enabled applications dynamically acquire and renew PSKs and use identity hints for PSK based authentication ceremony during a TLS handshake. It helps client-server applications dynamically acquire and renew PSKs using keyed-hash message authentication code (HMAC) for data integrity and authenticity, content signing, and data encryption for confidentiality. It helps manage and distribute API shared secrets and API access tokens required for authenticated API requests and API security. It helps applications (producers, brokers, and consumers of content) with PSKs for supply chain tamper resistance. It helps real-time low-latency applications with selective encryption of partial messages.
