TPM 1.2 vs TPM 2.0 – What are the differences?


In today’s business world, it is more important than ever to be able to think creatively. That’s where the concept of Thinking Process Modes comes in. There are two main modes of thinking: TPM 1.2 vs TPM 2.0. In this blog post, we’re going to take a look at the differences between these two modes, so that you can start using the right one for the task at hand.

1. What is TPM?

The Trusted Platform Module (TPM) is a hardware chip that provides a secure environment for storing cryptographic keys, digital signatures, and other sensitive data.

  • TPMs are used in a variety of applications such as computer security, network security, and others.
  • TPMs are typically implemented as a discrete component on the motherboard of a computer or server.
  • The TPM specifications are defined by the Trusted Computing Group (TCG), an industry consortium that promotes interoperability and standards for trusted computing.
  • TPMs provide a number of security features including tamper-resistance, integrity measurement, and remote attestation. TPMs can be used to protect the boot sequence of a computer from malicious code, prevent unauthorized access to data, and provide a chain of trust for software and firmware updates.
  • TPMs are an important part of the trusted computing platform that helps to improve the security of computing devices and networks.

2. Overview of TPM 1.2

Trusted Platform Module (TPM) technology is a hardware-based approach to security that provides a root of trust for platform integrity measuring and reporting. TPM 1.2 adds new capabilities and features while retaining full compatibility with TPM 1.1.


TPM 1.2 includes a number of new features and enhancements, the most notable of which are:

  • Improved bootstrap trust – TPM 1.2 allows the TPM to be used as part of the boot process, providing early measurement and validation of platform components before they are loaded into memory. This helps to ensure that only trusted software is executed on the platform.
  • Extended liquid crystal display (LCD) support – TPM 1.2 adds support for displaying measurements on LCDs, making it easier for end users to verify the integrity of their platforms. This allows businesses to deploy systems with tamper-evident displays without incurring additional costs.
  • Reduced power consumption – TPM 1.2 devices consume less power than their predecessors, making them more suitable for mobile and battery-powered applications. This also makes it possible to deploy TPMs in energy-sensitive environments such as data centers.

3. Overview of TPM 2.0

TPM 2.0, or Trusted Platform Module, is a specification for cryptographic modules that ensures security on devices equipped with it. TPM 2.0 provides greater flexibility and functionality compared to its predecessor (TPM 1.2), as well as increased security. In this blog post, we’ll provide an overview of TPM 2.0 and some of the benefits it offers.

It’s a major update from the previous version of the specification, TPM 1.2, which was released in 2006. The updated specification includes new features and improvements such as:

  • Improved support for RSA and Elliptic Curve algorithms
  • Greater flexibility in Key Generation, Storage, and Export
  • New Authorization Methods (including password-based authorization)
  • Enhanced Platform Configuration Registers (PCRs) management
  • And more!


There are many benefits to using TPM 2.0 modules, some of which include:

  • Improved Security: With TPM 2.0, you can take advantage of new features such as Auth Values and Platform Configuration Registers to increase the security of your device.
  • Increased Flexibility: The updated specification includes support for new algorithms and key types, giving you more options when it comes to configuring your device’s security settings.
  • Enhanced Usability: TPM 2.0 modules are backward compatible with TPM 1.2, meaning you can use existing software with the updated module without having to make any changes.

4. TPM 1.2 vs TPM 2.0

The main difference between TPM 1.2 and 2.0 is that TPM 2.0 offers additional features and capabilities that weren’t present in the earlier version. Here’s a more detailed breakdown of the differences between these two standards:

TPM 1.2:

• Supports basic cryptographic functions

• Can store up to 2048-bit RSA keys

• Is not compatible with non-Windows operating systems

TPM 2.0:

• Supports more advanced cryptographic functions

• Can store keys of up to 4096 bits

• Is compatible with all major operating systems, including Windows, Linux, and macOS

As you can see, TPM 2.0 is a more robust and versatile standard than its predecessor. However, that doesn’t necessarily mean that it’s the right choice for everyone. Let’s take a closer look at some of the key considerations you should keep in mind when deciding whether to go with TPM 1.2 or TPM 2.0.

5. TPM 1.2 vs TPM 2.0: What are the benefits of one over the other?

  • TPM 2.0 was developed to address the limitations of TPM 1.2 and to provide additional security features.
  • TPM 2.0 offers improved cryptographic capabilities, including support for larger key sizes and elliptic curve algorithms.
  • Additionally, TPM 2.0 provides better support for third-party software applications and allows for more flexible platforms.
  • TPM 2.0 also includes several new security features, such as an improved attestation process and enhanced authorization controls.
  • Overall, TPM 2.0 provides enhanced security capabilities that can help to protect against sophisticated attacks.

As businesses become increasingly reliant on digital technologies, the adoption of TPM 2.0 is likely to continue to grow.

6. How does TPM 2.0 work compared to TPM 1.2?

TPM 2.0 is the latest generation of Trusted Platform Module technology. Compared to TPM 1.2, TPM 2.0 offers a number of significant improvements. Perhaps most importantly, TPM 2.0 provides greater security by supporting multiple endorsement keys and up to 384-bit key sizes.

TPM 2.0 also offers improved performance, with faster cryptographic operations and support for larger data objects. In addition, TPM 2.0 is designed to be more flexible and extensible than its predecessor, with a modular architecture that supports new use cases such as attestation and sealing. Overall, TPM 2.0 represents a major step forward for Trusted Platform Module technology.
