A privacy protection authentication method based on a wireless body area network may be applied to a smart home care system. The method provides an authentication method for two-way authentication and key verification between a device and a cloud server, can ensure identities of the device and the cloud server to be valid and prevent network information security from being affected by external invasion attacks. A physical unclonable function and an elliptic curve cryptography algorithm are introduced to encrypt key data in the authentication process, so that the whole authentication process is in a safe environment, and the security of the authentication process is further improved through adding and removing functions of a third-party identity. The privacy protection authentication protocol method can resist replay attacks and smart card impersonation attacks, the whole authentication process is safe and efficient, and has a high application value in smart home care scenes.

An infrastructure delivery platform provides a proxy service as an enhancement to the TLS/SSL protocol to off-load to an external server the generation of a digital signature, the digital signature being generated using a private key that would otherwise have to be maintained on a terminating server. Using this service, instead of digitally signing (using the private key) “locally,” the terminating server proxies given public portions of ephemeral key exchange material to the external server and receives, in response, a signature validating the terminating server is authorized to continue with the key exchange. In this manner, a private key used to generate the digital signature (or, more generally, to facilitate the key exchange) does not need to be stored in association with the terminating server. Rather, that private key is stored only at the external server, and there is no requirement for the pre-master secret to travel (on the wire).

Operational n-state digital circuits and n-state switching operations with n and integer greater than 2 execute Finite Lab-transformed (FLT) n-state switching functions to process n-state signals provided on at least 2 inputs to generate an n-state signal on an output. The FLT is an enhancement of a computer architecture. Cryptographic apparatus and methods apply circuits that are characterized by FLT-ed addition and/or multiplication over finite field GF(n) or by addition and/or multiplication modulo-n that are modified in accordance with reversible n-state inverters, and are no longer known operations. Cryptographic methods processed on FLT modified machine instructions include encryption/decryption, public key generation, and digital signature methods including Post-Quantum methods. They include modification of isogeny based, NTRU based and McEliece based cryptographic machines.

Methods, systems, and computer programs are presented for lowering network latency for cloud-based services. Service-delivery edge locations allow customers to improve communication-providers public and private network connectivity for improved performance. One method includes operations for performing, by an edge server, a handshake to establish a communication session between a client and a main server, and for exchanging data between the client and the main server via the edge server. The handshake includes exchanging, by the edge server, communication initiation messages with the client, and validating, by the edge server, authentication credentials for the communication session based on the communication initiation messages. The exchanging data comprises forwarding, by the edge server, data requests from the client to the main server through a private connection between the edge server and the main server, and forwarding, by the edge server, data responses from the main server to the client through the private connection.

A method performed by a STA may comprise receiving a frame, from a first AP including an indication of a configuration change counter (CCC) associated with a second AP. The CCC may be an unsigned integer that increments when an update to one or more AP parameters of the second AP has occurred. The method may further comprise establishing a first wireless link with the first AP and establishing a master key via at least the first wireless link.

A method (300) and system (1) of determining a common secret for two nodes (3, 7). Each node (3, 7) has a respective asymmetric cryptography pair, each pair including a master private key and a master public key. Respective second private and public keys may be determined based on the master private key, master public key and a deterministic key. A common secret may be determined at each of the nodes based on the second private and public keys. In one example, a node (3, 7) may determine the common secret based on (i) a second private key based on the node's own master private key and the deterministic key; and (ii) a second public key based on the other node's master public key and the deterministic key. The invention may be suited for use with, but not limited to, digital wallets, blockchain (e.g. Bitcoin) technologies and personal device security.

A network can operate a WiFi access point with credentials. An unconfigured device can (i) support a Device Provisioning Protocol (DPP), (ii) record responder bootstrap public and private keys, and (iii) be marked with a tag. The network can record initiator bootstrap public and private keys, as well as derived initiator ephemeral public and private keys. An initiator can (i) operate a DPP application, (ii) read the tag, (iii) establish a secure and mutually authenticated connection with the network, and (iv) send the network data within the tag. The network can record the responder bootstrap public key and derive an encryption key with the (i) recorded responder bootstrap public key and (ii) derived initiator ephemeral private key. The network can encrypt credentials using the derived encryption key and send the encrypted credentials to the initiator, which can forward the encrypted credentials to the device, thereby supporting a device configuration.

Embodiments of a device and method are disclosed. In an embodiment, a method of communications involves from a wireless sensor deployed at a customer site, connecting to a wireless access point (AP) deployed at the customer site and based on a private key stored in the wireless sensor, performing mutual authentication between the wireless sensor and an authentication server connected to the wireless AP.

The present invention discloses a system and method of generating application specific keys using key derived from network access authentication.

A method includes extracting, by an individual computing system, physical movement intentions of an individual from neural signals; mapping, by a secure element of the individual computing system, the physical movement intentions to a character string representing a knowledge factor; and establishing, by the individual computing system, a secure, mutually authenticated communication channel between the individual computing system and a provider computing system by using the knowledge factor as an input to a password authenticated key exchange protocol and generating a symmetric encryption key using the knowledge factor as an input to a key exchange protocol.
