This represents the current standard of security used globally today, often referred to as Classical Cryptography.

Symmetric & Asymmetric Keys: Includes standard protocols like AES (Advanced Encryption Standard) and RSA.

Data Integrity: These methods provide the “confidentiality” and “integrity” for everyday transactions, banking, and emails.

Legacy Support: SMSE ensures that while moving toward the future, existing systems remain patched and secure against current threats using non-quantum, high-speed algorithms.
