This is the first in a series of posts that will go through the various elements of my config for the PS Vita, and how they may be useful to others. I have gone through the process of configuring my Vita for playing games on it, and have done it in a way that best suits my needs.

If you like playing games on your phone, you’re probably a bit bored with all the sites that are out there. You’re looking for something more. Something unique and fun. Someone to let you know what games are coming out for the next month and what other games you can play. That’s why I’m writing this blog. I’ll let you know what’s happening in the world of gaming, and I’ll let you know what games you should play.

Ever since Microsoft and Sony announced they were joining forces to create the Playstation 4, the gaming community has been buzzing. Microsoft has traditionally focused on providing game developers with a platform they can develop games for, but Sony has had a long history of using its Playstation brand to support a wide range of entertainment offerings. Combine this with Microsoft’s deep pockets and control over the Xbox brand, and we should be in for a good time…right? Well, not so fast. Both companies have spent decades building brands and expanding markets, so it’s hard to say which company has the upper hand. (And we still don’t know what the console’s name is yet.)

As you probably know, Windows 11 was recently announced and it brings with it a host of new features as well as some specific requirements.

As for the hardware requirements for Windows 11, the new change everyone is talking about is the TPM chip, and if you don’t have it, you won’t be able to upgrade to Windows 11 because of the TPM 2.0 bugs.

There are two versions of TPM and in this guide we will compare TPM 1.2 and 2.0 and see which one is better.

TPM 1.2 vs. 2.0, which one should I use?

Brief history of TPM

TPM was first introduced by the Trusted Computing Group in 2009 and has since been used in computers, ATMs and set-top boxes.

TPM 1.2 was published in 2005 and last revised in 2011. On the other hand, TPM 2.0 was originally released in 2014, and the latest revision dates back to 2019.

There are several differences between these two versions, but before we compare them, let’s take a look at what TPM does and how it protects your PC.

What is TPM?

TPM stands for Trusted Platform Module, a special microcontroller that provides encryption capabilities and an extra layer of security for your PC.

The TPM is usually a chip on the motherboard, but it can also be built into the processor or run separately in the firmware. Some motherboards are equipped with TPM connectors, so you can add the TPM chip yourself.

There is also a fully virtual TPM that works at the software level, but many experts say it is not as secure as its physical counterpart.

How does the TPM work?

The TPM is mainly used for encryption and generates and stores part of the encryption keys. This means that if you want to unlock the encrypted drive, you must use the same TPM chip that generated the encryption key.

Since the encryption key is not stored on the hard drive, it is harder for hackers to decrypt your data because they also need access to the TPM chip.

TPM chips also provide protection against fraud. So if the chip or motherboard is manipulated by a hacker, the TPM can still keep your data under lock and key.

In addition to encryption, the TPM can protect your computer from malware by inspecting the bootloader. If your boot loader is corrupted, the TPM will not allow your system to boot.

The TPM also has a quarantine mode that you can use to troubleshoot bootloader problems. Finally, TPM stores all your passwords internally, making them safe from hackers.

In other applications, TPM is used to manage digital rights, protect software licenses and, in some cases, prevent video game fraud.

TPM 1.2 vs. 2.0, what are the differences?

TPM 2.0 is an improvement over TPM 1.2 and although they are similar, you should know that TPM 2.0 is not compatible with TPM 1.2.

TPM 1.2 has a universal specification, while version 2.0 has platform-specific specifications that determine which parts of the library are mandatory or optional.

As for the TPM 1.2 algorithms, SHA-1 and RSA are mandatory and AES is optional. TPM 2.0 requires SHA-1 and SHA-256 for hashes.

RSA and ECC with 256-bit Barreto-Naehrig curve and NIST P-256 curve are used for public key cryptography and asymmetric digital signature creation and verification in TPM 2.0.

As for creating symmetric digital signatures, TPM 2.0 uses HMAC and 128-bit AES for symmetric key algorithms.

The difference between the algorithms is noticeable, making TPM 2.0 a much more secure solution.

As far as cryptoprimitives are concerned, TPM 1.2 and 2.0 offer the following:

  • Generation of random numbers
  • public-key cryptographic algorithm
  • Mask generation function
  • Create and verify a digital signature
  • Symmetric key algorithms

Although it has the same features, TPM 2.0 uses direct anonymous authentication with a 256-bit Barreto-Nerig curve, which makes its use more secure.

In terms of hierarchy, TPM 1.2 only has a storage hierarchy, while TPM 2.0 has a platform, storage and endpoint hierarchy.

For root keys, TPM 1.2 only supports the RSA-2048 SRK, while TPM 2.0 supports multiple keys and algorithms per hierarchy.

TPM 1.2 uses HMAC, PCR, location and physical presence for authorization. TPM 2.0 provides the same authentication features and password protection.

For NVRAM, TPM 1.2 supports unstructured data only, while TPM 2.0 supports unstructured data, counter, bitmap, expansion, PIN pass and fail.

As you can see, TPM 2.0 offers a number of improvements and is a more robust choice for data protection and encryption.

Here is a brief overview of the algorithms that support TPM 1.2 and TPM 2.0.

 

Algorithm Type: Name: RPM 1.2 RPM 2.0
Asymmetrical RSA 1024 Yes In addition,
RSA 2048 Yes Yes
ECC P256 No Yes
ECC BN256 No Yes
Symmetrical AES 128 In addition, Yes
AES 256 In addition, In addition,
Hush SHA-1 Yes Yes
SHA-2 256 No Yes
HMAC SHA-1 Yes Yes
SHA-2 256 No Yes

Why is TPM 2.0 better than TPM 1.2?

TPM 1.2 only uses the SHA-1 hash algorithm, which is problematic because SHA-1 is not secure and many authorities have switched to SHA-256 since 2014.

Microsoft and Google removed support for signing SHA-1-based certificates in 2017. It should also be noted that TPM 2.0 supports new algorithms that will improve performance in terms of disk signing and key generation.

TPM 2.0 also provides a more consistent experience and the lockdown policy is configured by Windows. In TPM 1.2, implementations differ in policy settings, which may pose a security risk.

Also note that some features, such as Device Encryption, Windows Defender System Guard, Autopilot and SecureBIO are only available if you are using TPM 2.0.

The following is a list of features that support TPM 1.2 and TPM 2.0:

 

  RPM 1.2 RPM 2.0
Measured boot
BitLocker
Device encryption
Controlling Windows Defender applications
Windows Defender System Defender
credit guard
Certification of the health of devices
Windows Hello
UEFI Secure Booting
TPM Platform Crypto Provider Keystore Provider

Autopilot
SecureBIO

Does Windows 11 need TPM 2.0?

When Windows 11 was first announced, the hardware requirements for Windows 11 indicated that Windows 11 would work with TPM 1.2 and TPM 2.0, the latter being the more secure option.

According to the documentation, upgrading to Windows 11 with a TPM 1.2 chip is allowed, but not recommended. However, Microsoft has updated the documentation and TMP 2.0 is now a requirement for Windows 11.

This suggests that TPM 2.0 is a requirement for Windows 11 and that users with TMP 1.2 chips will not be able to use Windows 11.

However, there is a way to install Windows 11 without TPM if you have technical knowledge. On the other hand, it looks like some Windows 11 systems will work without a TPM 2.0 chip, which is good news for many.

Is the TPM only for business customers?

Although TPM was originally developed for business users, the technology is now also available for home PCs.

While data encryption is not a requirement for individuals, file encryption and the use of TPM are essential if you want to ensure the ongoing security of your files.

Not all encryption requires a TPM, but using one provides a level of hardware security that makes it harder for hackers to access your data.

It provides unbreakable protection, so you can rest assured that your encrypted files will remain safe from hackers, even if they try to modify your hardware.

TPM is not only used to encrypt files, and probably you use it as a home user without knowing it. If you are using Windows Hello, you are already using the TPM.

Your passwords and PINs are also stored in the TPM, even for home users. Finally, the TPM provides a secure boot function that prevents boot loaders from infecting your computer.

So even if you are not a business customer and do not encrypt your data, you still benefit from TPM as a residential user.

Supplement

TPM 1.2 and TPM 2.0 have their advantages and with the recently announced Windows 11 requirements, TPM chips are mandatory. So if you don’t have a TPM chip, you should consider getting one.

So which version of TPM is better? The answer is quite simple, TPM 2.0 is newer, more secure and offers more security features, it works better with Windows and we can safely say that TPM 2.0 is a better choice than TPM 1.2.
