摘要： A system(s) and method(s) for secure session establishment and secure encrypted exchange of data is disclosed. The system satisfies authentication requirement of general networking/communication systems. It provides an easy integration with systems already using schemes like DTLS-PSK. The system follows a cross layer approach in which session establishment is performed in a lightweight higher layer like the application layer. The system then passes resultant parameters of such session establishment including the session keys to a lower layer. The lower layer like the transport layer is then used by the system to perform channel encryption to allow exchange of encrypted data based on a cross layer approach, over a secure session. As the exchange of data becomes the responsibility of the lower layer like the transport layer, the data is protected from replay attacks since the transport layer record encryption mechanism provides that kind of protection.

摘要： A computer implemented system and method for lightweight authentication on datagram transport for internet of things provides a robust authentication scheme based on challenge-response type of exchanges between two endpoints sharing a pre-shared secret. A symmetric key-based security mechanism is utilized in the present disclosure where key management is integrated with authentication. It provides mutual authentication wherein the end-points in the system are provisioned with a pre-shared secret during a provisioning phase and a client database is provided at the server side for client identification. The system comprises random number generators for generation of nonces, and key generators to generate secret key and session key. The nonces and keys are valid only during the session and thus help in providing secure authentication across sessions.The system can be further adapted on transport layer security protocols like DTLS and can be integrated with application layer protocols like CoAP for constrained devices.

摘要： A detection system for detecting the presence and direction of a subject moving through a doorway is disclosed. The system comprises magnets disposed on the doorway, a communication device, typically a smartphone and a server. The magnets are positioned on the doorway to create a magnetic field across the doorway. When the subject having the smartphone on the body passes through the doorway, a magnetometer in the smartphone senses perturbations caused by the magnetic field and generates signals corresponding to the sensed perturbations and a processor of the smartphone processes the signals to detect the presence and direction of the subject through the doorway. The data generated by the processor and a unique identification associated with the smartphone is transmitted to the remotely located server.
