Can I use SKM for End-to-End Encryption

I need a solution

Currently, I'm assisting a customer to deploy their Encryption Platform:

  • Encryption Management Server
  • Gateway Email
  • Desktop Encryption
  • Mobile Encryption (iOS & Android devices).

 

Talking just around Messaging Encryption. Customer wants to build a rule for automatic encryption from the email desktop client (Outlook) to all messages that she send to a named internal users group (all users in this group are provisioned in Encryption Management Server).

In detail, customer wants:

  • When she send an email to another internal user that belongs to a specific group: Always encrypt
  • When she send an email to another internal user that doesn't belongs to that group: Send in clear text
  • When she send an email to an external user: Send in clear text
  • When she send an email to an external user but with a keyword in subject: Encrypt and deliver using PDF Messenger

All users have keys in SKM mode . So, I would like to know if this is the best mode for this scenario.

Administrative premises are:

  • All users need to be able to check encrypted messages on their mobile devices (Android & iOS)
  • Keys (Public and private) must be able to be backed up centrally
  • All users must be able to encrypt automatically (based on rules) or on-demand (using the Encryption Outlook addin), from their desktop computers.

Customer has Exchange Server 2010. All users use Windows+Outlook computers.

 

It's Ok to continue using SKM mode keys?

Thanks
