The invention discloses a session key generation device and method. According to the session key generation device and method provided by the embodiment of the invention, the first communication module and the second communication module perform identity mutual recognition through the first identity verification information and the second identity verification information, and generate the session key according to the first identity verification information and the second identity verification information. According to the session key generation device and method provided by the embodiment of the invention, the identity of the session object is judged in the negotiation process of the session key, and identity verification can be realized without depending on a public key and a CA certificate system, so that the efficiency of generating the session key is improved, and the security of the session key is improved.
Description
technical field [0001] The invention relates to the technical field of key agreement, in particular to a session key generation device and method. Background technique [0002] With the development of communication technology and information processing technology, more and more attention has been paid to the security of information during transmission. The use of encryption keys in the communication process is an encrypted communication method commonly used in encrypted communication at present. The key agreement is mainly to allow the communication parties to establish a temporary session key, that is, two or more participants in the system provide information together, and each derive a shared key that cannot be predetermined by any party. [0003] Once the encryption key is cracked, the subsequent encrypted information will no longer be safe. Therefore, in order to prevent the encryption key from being cracked, various key agreement mechanisms have emerged. However, wi...
