Which encryption methods does SESAME utilize?

SESAME, which stands for Secure European System for Applications in a Multivendor Environment, implements a flexible security infrastructure that utilizes both symmetric and asymmetric encryption methods. This dual approach enhances security by leveraging the strengths of both encryption types.

Symmetric encryption is used for performance efficiency in data encryption, as it is generally faster and suitable for encrypting large amounts of data. On the other hand, asymmetric encryption comes into play during key exchange and authentication processes. It allows for secure communication and the establishment of trust by enabling users to exchange keys in a secure manner without needing a pre-shared secret.

The combination of these encryption methods allows SESAME to provide robust authentication mechanisms, ensuring that both the identity of the user and the integrity of the data are maintained throughout the communication process. This multifaceted approach to encryption is essential for operating securely in a diverse, multivendor environment, where different systems must interoperate while still adhering to strict security standards.
