The Qualcomm APQ8096 handles encrypted data through a combination of hardware and software features designed to ensure data security and integrity. Below are the detailed specifications and mechanisms involved in its encryption capabilities:

### Hardware Security Features

1. Trusted Execution Environment (TEE):
- The APQ8096 integrates a secure TEE that provides a safe execution area for sensitive operations, including encryption and decryption processes. This isolated environment helps protect against unauthorized access and ensures that cryptographic keys are handled securely.

2. Cryptographic Acceleration:
- The chipset includes dedicated hardware accelerators for cryptographic algorithms. This hardware support enhances performance and reduces latency during encryption and decryption tasks. Common algorithms supported include AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and ECC (Elliptic Curve Cryptography).

3. Secure Boot:
- The APQ8096 employs secure boot mechanisms to ensure that only authenticated and authorized software can run on the device. This process verifies the integrity of the firmware and operating system at startup, protecting against tampering and unauthorized access.

4. Hardware Random Number Generator (RNG):
- A secure hardware RNG is integrated to generate cryptographic keys and other random values required for encryption processes. The use of a hardware RNG enhances security by providing high-quality randomness that is crucial for cryptographic operations.

### Software Security Features

1. Operating System Support:
- The APQ8096 is typically paired with secure operating systems (like Android or custom embedded systems) that implement software-level encryption protocols. These operating systems use APIs to access hardware features and facilitate secure data handling.

2. Full Disk Encryption (FDE):
- The platform supports full disk encryption, which encrypts the entire storage volume of the device. This ensures that all data, including files and application data, is encrypted at rest, protecting sensitive information from unauthorized access.

3. Application-Level Encryption:
- Developers can utilize various libraries and APIs to implement application-level encryption, allowing specific data or files to be encrypted individually. This provides greater control over data security and enables tailored encryption strategies based on application needs.

4. Data-at-Rest and Data-in-Transit Protection:
- The APQ8096 supports encryption protocols for both data-at-rest and data-in-transit. For data-at-rest, it employs AES encryption for stored files. For data-in-transit, it can utilize protocols such as TLS (Transport Layer Security) to encrypt data transmitted over networks, ensuring that sensitive information is protected during transmission.

### Compliance and Standards

1. FIPS Compliance:
- The APQ8096 can be configured to comply with FIPS (Federal Information Processing Standards) requirements for cryptographic modules. This compliance ensures that the encryption methods used meet rigorous government security standards, making the chipset suitable for use in sensitive applications.

2. Secure APIs:
- Qualcomm provides secure APIs for developers, allowing them to implement robust encryption and security practices in their applications. These APIs facilitate the use of hardware-based encryption features, ensuring secure handling of sensitive data.

### Summary

The Qualcomm APQ8096 leverages a combination of hardware and software security features to handle encrypted data effectively. Its integrated Trusted Execution Environment, cryptographic accelerators, secure boot mechanisms, and support for various encryption standards enable it to provide a secure platform for applications that require the protection of sensitive information. By combining these elements with secure operating system support and application-level encryption, the APQ8096 ensures a comprehensive approach to data security in embedded and IoT applications.
