+ *《影片介紹》BBM Protected - Secure IM
+ *PROTECT DATA IN-TRANSIT
+ *BBM Protected is designed to provide full end-to-end message encryption from the time a BBM Protected user sends a message to when the recipient receives the message. It incorporates three layers of security.
+ *BBM Protected introduces a new layer of encryption to the existing BBM security model.
+ *Messages between BBM Protected users are encrypted using a PGP like model. The sender and recipient have unique public/private encryption and signing keys.
+ *These keys are generated on the device, by the FIPS 140-2 certified cryptographic library, and are controlled by the enterprise.
+ *BBM and BlackBerry are not involved in brokering the key exchanges, so at no time are they stored within the BlackBerry infrastructure.
+ *Each message uses a new random symmetric key for message encryption.
+ *A Triple DES 168-bit BBM scrambling key encrypts messages on the sender’s smartphone, and is used to authenticate and decrypt messages on the recipient’s phone.
+ *TLS encryption between the smartphone and the BBM infrastructure helps protect BBM messages from eavesdropping or manipulation.

+ *可能架在 g0v 下然後開放 NGO 申請加密頻道，以降低技術門檻？
