Secure Element

November 21, 2023 - Around 4 mins mins to read

A Secure Element (SE) is a specialized hardware chip that is designed to securely store confidential data and execute specific applications while facilitating controlled access. It is a microprocessor chip that is particularly well-suited for handling sensitive information such as payment details, personal identification numbers (PINs), passwords, and more, depending on its intended use.

In the realm of blockchain and cryptocurrency, the Secure Element is primarily used to securely store and protect private keys in hardware wallets like Ledger and CoolWallet. Private keys are crucial for accessing and managing cryptocurrency assets, and the Secure Element adds an extra layer of security by keeping these keys isolated and protected from potential threats.

The Secure Element is assigned a CC EAL rating ranging from 1 to 7. CC stands for Common Criteria, which is an international standard for evaluating the security of IT products and systems. The higher the EAL rating, the more stringent the security requirements and evaluations for the Secure Element. This rating helps users determine the level of trust they can place in the Secure Element for safeguarding their sensitive information.

While the Secure Element is commonly associated with cryptocurrencies, it is also used in various other industries. In the identity industry, for example, the Secure Element interacts with certificates and biometric data. Devices like mobile phones and cold wallets incorporate Secure Element technology to provide secure storage and processing for sensitive identity information.

One of the key features of a Secure Element lies in its access restrictions. The chip only allows pre-installed programs and limits read and/or write privileges to trusted devices and applications. This means that only authorized programs and devices are allowed to interact with the Secure Element, reducing the risk of unauthorized access and potential attacks.

Secure Elements are available in various forms, including Universal Integrated Circuit Cards (UICCs) and microSD hardware cards. These form factors allow for the integration of the Secure Element into different devices and enable secure storage and processing of sensitive information.

In addition to physical form factors, some Secure Elements operate on the cloud. Cloud-based Secure Elements offer a seamless user experience while maintaining the security provided by microprocessors. This cloud-based approach reduces the cost associated with using a physical hardware chip on a host device and allows for secure access to sensitive information from anywhere with an internet connection.

When implemented at the hardware level, the Secure Element can detect alterations and thwart hacking attempts. It is designed to have built-in mechanisms that detect any tampering or unauthorized access, ensuring the integrity of the stored data. It also provides secure memory for storing critical private data like encryption keys and can generate key combinations for asymmetric encryption, further enhancing the overall security of the system.

With its advanced security features, the Secure Element plays a crucial role in various areas. In authentication, for example, it can be used to securely store and process digital certificates, ensuring the identity and integrity of individuals and systems. It is also used for digital signatures, allowing users to sign documents and transactions with cryptographic proof of authenticity and integrity.

Contactless or NFC payments also rely on the Secure Element for secure storage and processing of payment information. The chip ensures that payment details are protected from unauthorized access and that transactions are executed securely and efficiently.

Furthermore, the Secure Element is essential for cryptocurrency wallets. As mentioned earlier, hardware wallets like Ledger and CoolWallet utilize Secure Elements to store private keys securely. By keeping the keys isolated from the internet and potential threats, hardware wallets provide a higher level of security compared to software-based wallets.

In addition, the Secure Element is used for the storage of biometric data. Biometrics, such as fingerprints or facial recognition, are increasingly used for authentication purposes. The Secure Element can securely store and process biometric data, ensuring that it remains protected and cannot be easily tampered with or exploited.

In summary, a Secure Element is a specialized hardware chip that provides enhanced security for storing and processing sensitive information. It plays a vital role in various industries, including blockchain and cryptocurrency, identity management, authentication, payments, and biometrics. By isolating and protecting critical data, the Secure Element adds an extra layer of security and helps mitigate potential risks and threats.
