We have never used this option (see pix at end) in our Outlook 2010 and wanted EE help for proper decision making:

How secure is this "Encryption"?

Which encryption is it? AES?

When sending the email, will it make the Send (or outgoing) slower?

Do the recipient received the private key automatically or do we have to send it to each of them?

If we have the email option using secure incoming/outgoing (see pix below), should we use the 'email security' in Trust Center?


 

Questions on e-meial security Encryption Contents for Outlook 2010 outgoing messages

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
