What Are Cryptographic Applications in Identity Cards?

Identity cards are embedded with cryptographic mechanisms to secure personal information, prevent forgery, and enable secure communication. The technology leverages:

1. Encryption: Protects stored data from unauthorized access.
2. Digital Signatures: Verifies the authenticity of cardholders.
3. Public Key Infrastructure (PKI): Facilitates secure communication between card systems and servers.

Key Features Highlighted in Section 12.6

1. Secure Storage of Data
Cryptographic methods ensure that sensitive data, such as biometric information, is encrypted using robust algorithms like AES-256. Even if the card is lost, the data remains protected.

2. Authentication Mechanisms
Identity cards use cryptographic protocols like RSA or ECC to validate the user’s identity. The mutual authentication process ensures that both the card and the verifying system trust each other.

3. Anti-Counterfeiting Techniques
The case study in Section 12.6 emphasizes techniques like digital watermarks and tamper-resistant microchips to prevent duplication or tampering.
