INFORMATION PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/052086
Kind Code:
A1
Abstract:
An information processing method and apparatus, applied to a computer system deployed with a rich execution environment (REE) and a trusted execution environment (TEE). A target TA receives a password setting request sent by a target CA in the REE, the password setting request comprising a first password; then the target TA encrypts the first password with a first encryption parameter to obtain a first ciphertext, the first encryption parameter comprising a first security key derived from a security device deployed on the TEE; and the target TA can send the password setting result to the target CA, the password setting result comprising the first ciphertext. The first security key derived from the security device has higher security and is hard to steal, so that the difficulty in decoding the first ciphertext is improved, thereby increasing the security of the first password.
