发明名称 System and method for securing data for redirecting and transporting over a wireless network
摘要 A system and method for securing data for redirecting and transporting over a wireless network are generally described herein. In accordance with some embodiments, when it is determined that an electronic message that is protected with a first encryption algorithm is to be transported over a wireless network to a wireless device, the electronic message is converted to a data structure that is recognizable by the wireless device and the data structure is encrypted with a second encryption algorithm using a random session key. The second encryption algorithm has a stronger security than the first encryption algorithm. The random session key is encrypted with a public key and packets that comprise the encrypted data structure and the encrypted random session key are transmitted to the wireless device over the wireless network.

主权项 1. A method performed within a protected network for redirecting electronic messages for transporting over a wireless network to a wireless device, the method comprises: determining when an electronic message that is protected with a first encryption algorithm is to be redirected over the wireless network to the wireless device based on information within the electronic message, the wireless network being external to the protected network; when the electronic message is to be redirected over the wireless network, the method comprises: converting the protected electronic message to a data structure that is recognizable by the wireless device; encrypting the data structure with a second encryption algorithm using a random session key, the second encryption algorithm having a stronger security than the first encryption algorithm; encrypting the random session key with a public key; and transmitting packets that comprise the encrypted data structure and the encrypted random session key to the wireless device over the wireless network, and when the electronic message is not to be redirected over the wireless network, the method comprises: refraining from converting the protected electronic message, refraining from encrypting the data structure, refraining from encrypting the random session key and refraining from transmitting the packets over the wireless network; and sending the protected electronic message to a destination within the protected network.
