Data storage and encryption with a high security level based on molecular configurational isomers.

Area of Science:

• Materials Science
• Chemical Engineering
• Data Security

Background:

• Current data-encryption materials pose risks of data leakage due to chemical differences between message and substrate areas.
• Existing decryption methods often rely on single stimuli, offering limited data security.

Purpose of the Study:

• To develop advanced materials for highly secure data-encryption.
• To create a data-encryption method resistant to sophisticated instrumental analysis and single-stimulus decryption.

Main Methods:

• Utilized three configurational isomers: propylamine, isopropylamine, and cyclopropylamine, for data encryption.
• Leveraged the distinct lower critical solution temperatures (LCST) of their corresponding polyacrylamides for decryption: poly(N-propylacrylamide) at 10 °C, poly(N-isopropylacrylamide) at 32 °C, and poly(N-cyclopropylacrylamide) at 53 °C.

Main Results:

• Achieved secure data hiding by exploiting similar physiochemical properties of isomeric amines.
• Enabled effective data decryption through specific temperature ranges, not just simple temperature changes.
• Demonstrated that incorrect temperatures yield false outputs, increasing deception against unauthorized access.

Conclusions:

• The developed method offers a high level of data security by requiring specific temperature conditions for decryption.
• This approach provides a new paradigm for designing advanced materials to enhance data-security levels.
