What is Secure Element?

A secure element is a specialized piece of hardware that's built to handle specific tasks and keep sensitive data safe.

Get to Know with Secure Element

A secure element (SE) is a hardware chip created for running designated applications, ensuring controlled access, and safeguarding confidential information. This microprocessor chip is particularly useful for managing payment details, PINs, passwords, and other sensitive data depending on its intended use.

In the realm of cryptocurrencies, it's commonly utilized to securely seal and protect private keys in hardware wallets like Ledger and CoolWallet, often boasting a flexible CC EAL rating between 1 and 7.

How Does Secure Element Work?

For instance, within the identity sector, SE interacts with certificates and biometric data. Devices utilizing SE technology include mobile phones and cold wallets.

The primary feature of a secure element is its controlled access mechanism, ensuring top-notch security. By permitting only pre-installed programs and limiting read and/or write permissions to trusted devices and applications like point-of-sale terminals and virtual storage, the chip bolsters security measures.

Secure Elements Availability

Secure elements are available in various forms, such as UICCs (universal integrated circuit cards) and microSD hardware cards. Moreover, SEs can be embedded in devices, either as embedded UICCs or embedded SEs, offering flexibility.

Additionally, some SEs operate via the cloud, reducing the need for physical hardware chips on host devices while maintaining security standards and user experience.

Secure Storage and Secure Hacking Attempts

At the hardware level, SEs can detect alterations and repel hacking attempts. They also offer secure storage for critical private data like encryption keys and facilitate the generation of key combinations for asymmetric encryption.

Conclusion

SEs play pivotal roles in areas like authentication, digital signatures, contactless or NFC payments, cryptocurrency wallets, and biometric data storage, underscoring their significance in various domains.
