Abstract

The invention discloses an encryption communication device. The encryption communication device comprises an obtaining module which is used for obtaining to-be-encrypted communication data when a mobile terminal carries out encryption communication; an encryption module which is used for calling an encryption algorithm stored in a read-only memory to encrypt the to-be-encrypted communication data, thereby obtaining encrypted communication data; and a sending module which is used for sending the encrypted communication data to the opposite end of the encryption communication. The invention also discloses an encryption communication method. According to the method and the device, other hardware does not need to be added in the mobile terminal to encrypt the communication data; only the encryption algorithm is written in the read-only memory of the mobile terminal; and the encryption communication cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an encryption communication method and device. Background technique [0002] Many applications and mobile phone manufacturers now support file encryption, that is, they can protect the local data of the mobile phone, but there are few protection schemes for the communication data in the communication process, such as call data and SMS data. [0003] At present, a common scheme for encrypting communication data is to embed the encryption algorithm into the TF card. During the encrypted communication process, the communication data is transmitted to the TF card, and the encryption algorithm in the TF card encrypts the communication data. Then send the encrypted communication data to the opposite end of the encrypted communication. When the mobile terminal at the opposite end receives the encrypted communication data, it also needs to have a TF card with encryption and ...
