Four patents co-invented during my time on VMware’s Office of the CTO R&D team, all filed the same day and centered on one problem: how do you let multiple parties compute on sensitive data together (for federated learning, for aggregation) without any one of them seeing the others’ raw data? Secure Multi-Endpoint Cipher Negotiation establishes how endpoints agree on encryption terms in the first place; the other three build “cryptographic agility” into privacy-preserving computation itself, so the underlying scheme can adapt without breaking the privacy guarantee.
