Title: A METHOD OF DOWNLOADING DIGITAL CERTIFICATION AND KEY
Abstract:
A method of downloading digital certification and key, a download request side creates the digest of the first synthesized information according to the first digest algorithm, uses the digest to generate a encryption key according to the first key generation algorithm and encrypts the attribute information of itself, then creates download a request message according to the encryption content and digest and sends it to a download serving side. After receiving the request message, the serving side uses the digest to generate the encryption key according to the first key generation algorithm, and decrypts the encryption content in the message, and gets the attribute information of the download request side. When the serving side confirms the validity of the attribute information, the serving side inquires the corresponded digital certification and terminal private key according to the attribute information, and uses the second synthesized information to generate the encryption key according to the second key algorithm. The serving side encrypts the digital certification and terminal private key, creates a download response message and sends it to the request side. After receiving the second synthesized information, the request side generates the encryption key according to the second key generation algorithm, decrypts the ecnryption content of the response message, and gets requested digital certification and key.
