Hi Mathew! You are welcome for the response. I am happy to answer more questions.
1. Cross Platform AES Symmetric Key Cryptography - Read Blog Article<http://blog.pubnub.com/pubnub-adds-cross-platform-aes-symmetric-key-encryption/> 1. Basically Full Round-trip Cryptography of Data (Beyond SSL) - Though your data is encrypted as it travels through the Internet, it must be decrypted (and re-encrypted) as it passes through the PubNub servers and back out again. This is not a limitation of PubNub, but simply a limitation of the way SSL works. 2. In regards to the Send/Receive permissions: Exclude the *PUBLISH KEY* in order to prevent sending of data. 2. SHA256/HMAC Message Origin Signing 1. This happens automatically when you include the *SECRET KEY*. 3. Reliability - Globally Distributed. 1. We operate in 10 Discrete Physical Locations (different buildings). 2. The most recent EC2 outage on the East Coast was mitigated and customers were routed to the healthy data centers. 4. Socket.IO + PubNub 1. PubNub is a Cloud Messaging Service (Send/Receive) 2. Socket.IO is a higher-level interface that provides extra functionality on top of a Message Bus like PubNub. 3. You can think of Socket.IO like a jQuery type library that sits on top of the base infrastructure. 5. Locksetp Synchronization with Everyone on Earth. 1. This means that data is replicated quickly to all devices. For example if a Sport Score was updated while a game was in progress, this update would be sent as a PubNub message and all phones would be updated at the same time; all people would see the score update at the same time. 2. This type of application is perfect with PubNub Galaxy, our Mass Fan-out service: http://www.pubnub.com/solutions/pubnub-galaxy Glad to be of assistance!
