In the face of increasing cyber threats, there is a pressing need to secure the confidentiality of information in transit as well as to prevent the leakage of sensitive data.

To enhance information security, DSTA developed the Voynich Secure Email and Conficrypt tools which encrypt emails and documents respectively. The DSTA team modified the cryptographic algorithm of the encryption process to strengthen the encrypted information against cryptographic attacks.

The team also considered usage patterns and deployment contexts in enhancing user experience. For example, certain security parameters that remained constant for each deployment scenario were cached and meta-data was stored in the secure emails. As a result, the encryption and decryption speeds increased significantly.

With these solutions, users can continue to exchange important and confidential information rapidly and securely.
