Google Drive/Dropbox like solutions with Offline access and local security and Cross Platform [closed]

Question

Are there any software solutions or SDKs parts that handle the following:

• Propose something like google docs or dropbox, with secured storage for enterprise
• Documents are stored for offline access
• Documents are encrypted
• Solution work on iOS, Android and if possible Windows / Mac OS

I know that google docs will propose offline access and distribute an application on IPad but I would like to know if there are alternatives ?

Thank you

Regards
