Key protection processing method, apparatus, device and storage medium

A key protection processing method, which is applied to a second electronic device and comprises:

• receiving a first public key from a first electronic device, wherein the first public key is generated according to a first private key;
• generating a first encryption key according to the first public key and a pre-stored second private key;
• generating a second public key according to the pre-stored second private key, and sending the second public key to the first electronic device;
• wherein the second public key is used to generate a second encryption key, the second encryption key is generated according to the second public key and the first private key and the first encryption key and the second encryption key are used to process an original key used in data interaction between the first electronic device and the second electronic device.

A key protection processing apparatus, which is applied to a first electronic device and comprises:

• at least one processor;
• and
• a memory communicatively connected with the at least one processor;
• wherein,
• the memory stores instructions executable by the at least one processor, and the at least one processor, when executing the instructions, is configured to:
• generate a first public key according to a pre-stored first private key, wherein the first public key is used to generate a first encryption key, and the first encryption key is generated according to the first public key and a second private key;
• send the first public key to a second electronic device;
• receive a second public key from the second electronic device, wherein the second public key is generated according to the second private key;
• generate a second encryption key according to the second public key and the first private key;
• wherein the first encryption key and the second encryption key are used to process an original key used in data interaction between the first electronic device and the second electronic device.
