Core Security Implementation

Data Protection & Encryption

// AES-256 encryption for sensitive data
class SecureDataStore {
    private val masterKey = MasterKey.Builder(context)
        .setKeyScheme(MasterKey.KeyScheme.AES256_GCM)
        .build()
        
    private val encryptedPrefs = EncryptedSharedPreferences.create(
        context,
        "secure_prefs",
        masterKey,
        EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
        EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
    )
}

Authentication Security

• Multi-Factor Authentication: PIN + Biometric + Device binding
• Session Management: Secure token handling with refresh mechanisms
• Biometric Implementation: Android BiometricPrompt with CryptoObject
• Password Policy: Complexity requirements and rotation
• Account Lockout: Progressive delays and threshold limits
