Method and apparatus for secure communication between user equipment and private network

摘要: It is an object of the present invention to provide a new technical solution supporting special secure communication between user equipment which located in external network and private belongs to. Specifically, transmitted data encrypted/decrypted authenticated by using pre-stored root keys corresponding specific networks agreed encryption/decryption authentication algorithm at access device. The manner generating key simplified, complexity device end reduced on premise not degrading security grade. highly flexible extensible can achieve better experience.
