Provide an overview of the types of public-private key pairing, and show how this provides authentication and nonrepudiation. You will also add hashing, and describe how this added security benefit ensures the integrity of messaging.
Begin preparing your strategy by reviewing the following resources that will aid you in becoming well informed on encryption technologies for e-mail:
- Public Key Infrastructure (PKI)
- iOS encryption
- Blackberry encryption
Then start developing your strategy. Define these strong encryption technologies as general principles in secure email:
Pretty Good Policy (PGP algorithm)
- GNU Privacy Guard (GPG)
- Public Key Infrastructure (PKI)
- Digital signature
- Mobile device encryption (e.g., iOS encryption and Blackberry encryption)
In your report, also consider how the use of smart card readers tied to computer systems might be beneficial in the future enhancements to system and data access protection. This may help you define long-term solutions for your leadership.
Leadership does not know the costs and technical complexity of these email encryption strategies. To further their understanding, compare the complexities of each in relation to the security benefits, and then make a recommendation and a deployment plan.
