A communication apparatus capable of easily identifying a communication partner and securely sharing a session key between the communication apparatus and the communication partner even if the communication apparatus has a processing power that is not so high includes a short-range active communication unit 101 transmitting an inquiry signal to a short-range external communication apparatus by electromagnetic waves and waiting for a response to the inquiry signal; a long-range communication unit 104 capable of communication by the electromagnetic waves in a range wider than the communication area of the short-range active communication means; a switching unit 111 switching to either the short-range active communication unit or the long-range communication unit; and an asymmetric key generator 102 generating a pair of an encryption key and a decryption key corresponding to the encryption key. The communication apparatus is characterized by using the decryption key to decrypt an encrypted session key transmitted from the external communication apparatus and transmitting to the external communication apparatus a communication switching request signal to request the switching to the long-range communication unit and communication by using the long-range communication unit.

The invention provides a digital identity authentication method based on a secure two-dimensional code, comprising that: the third party application initiates an authorization login request; the identity authentication SDK obtains a session key from the server; the identity authentication SDK encrypts the information of the third party application through the session key, and sends the encrypted information and the authorized login request to the server; the server decrypts through the session key to obtain the information of the third-party application, generates a two-dimensional code and atwo-dimensional code url, and encrypts the two-dimensional code url by using a key, and the identity authentication SDK obtains the encrypted two-dimensional code url; the identity authentication SDKdecrypts the encrypted two-dimensional code url, then the third-party application jumps according to the two-dimensional code url to display the two-dimensional code; and the user scans the two-dimensional code for authentication to authorize the third-party application to log in. The invention also provides a digital identity authentication system based on the secure two-dimensional code to ensure the security of the authorization process and the secure login of the third-party application.

The invention discloses an information encryption, decryption and control method and device and electronic equipment. The method comprises the steps of: enabling an initiator to obtain a secret key IDwhich is sent by a server and used for identifying a communication service and a secret key corresponding to the secret key ID at a terminal; decrypting a session key for encrypting and decrypting the communication service according to the key; and encrypting the communication service according to the session key so as to realize an encryption function on the communication service; enabling the participant to obtain a secret key ID sent by the initiator at the terminal; obtaining a secret key corresponding to the secret key ID from a server according to the secret key ID; decrypting a group session key used for decrypting the communication service according to the key so as to realize a function of decrypting the communication service; and enabling the server to generate the same secret key at different secret key management service sites, so that the same secret key can be obtained when a plurality of nodes communicate at the same time, and each terminal can perform encryption communication service conveniently.
