Abstract: Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key.

Abstract translation: 用于通过网络进行安全通信的有限计算资源的网络设备的认证。 设备的认证开始于请求者节点向代理节点发送具有其认证凭证的签名数字证书。 在验证证书后，代理节点然后通过网络可访问的认证服务器来认证请求方的凭据，充当请求方节点的代理。 通常，该验证包括根据公共/私人密钥方案的解密。 成功认证后，认证服务器为请求方节点创建会话密钥，并将其与代理节点进行通信。 代理节点用对称密钥加密会话密钥，并将加密的会话密钥发送给请求方节点，该请求者节点在解密之后使用会话密钥进行安全通信。 在一些实施例中，认证服务器用对称密钥加密会话密钥。
