Title: ENCRYPTION AND DECRYPTION PROCESSING METHOD, APPARATUS AND DEVICE
Abstract:
Provided in the embodiments of the present invention are an encryption and decryption processing method, apparatus and device. The method comprises: the device self-generating a key pair comprising a first key for encryption and a second key for decryption; the device storing the key pair in a first storage space of the device, wherein the first storage space not providing external access; the device performing an abstract operation on device running data to obtain an abstract of the device running data, and the device running data is stored in a second storage space of the device; the device reading the first key from the first storage space; and encrypting the abstract of the device running data using the first key, to obtain a first digital signature. The embodiments of the present invention enable an effective reduction of the possibility of key leakage, thereby accordingly improving safety.
