Title: INFORMATION TRANSMISSION METHOD AND MOBILE DEVICE
Abstract:
Disclosed are an information transmission method and a mobile device. The method comprises: a first mobile device receives plaintext information of a user in a first execution environment and encrypts same in an advanced execution environment; then the first mobile device sends ciphertext information to a second mobile device; after receiving the ciphertext information, the second mobile device decrypts same in the advanced execution environment, and then displays to the user the plaintext information, which is not persistently stored and would be destroyed under a predetermined condition, wherein the security and trustable level of the advanced execution environment is higher than that of the first execution environment. By means of the method, the security of communication information can be improved.
