What is the secure element?
Secure Element (SE) is a tamper-proof microprocessor chip. It stores sensitive data and runs secure, trusted apps. This helps it keep the data and applications safe from other applications running on the same device. SE is used in smartphones, tablets, wearables and other Internet of Things devices.
What is TEE and REE?
REE stands for “Resting Energy Expenditure,” or the number of calories (kcal) required by the body at rest. Total Energy Expenditure (TEE) takes into account one’s activity level and (if applicable) desired weight loss per week.
Is TrustZone a TEE?
Not all code running in Arm® TrustZone® technology isolated environment conforms to the above ideals of a TEE, though it is a great place to build a TEE.
What is a TrustZone?
Arm TrustZone technology offers an efficient, system-wide approach to security with hardware-enforced isolation built into the CPU. It provides the perfect starting point for establishing a device root of trust based on Platform Security Architecture (PSA) guidelines.
How do secure elements work?
A Secure Element (SE) is a microprocessor chip which can store sensitive data and run secure apps such as payment. It acts as a vault, protecting what’s inside the SE (applications and data) from malware attacks that are typical in the host (i.e. the device operating system).
What is secure element application?
To provide better security, some devices have an embedded Secure Element (SE), which is dedicated, separate tamper-resistant hardware to store cryptographic data. Open Mobile API is a standard API used to communicate with a device’s Secure Element.
How do I find my REE?
The equation for males is:
- 66 + (13.7 x weight) + (5 x height) – (6.8 x age) And for females it is:
- 655 + (9.6 x weight) + (1.85 x height) – (4.7 x age) The formulas are from Katch, McArdle & Katch (2011).
What is normal REE?
Resting energy expenditure (REE) represents 60% to 70% of total energy expenditure (TEE). In asymptomatic adults with HIV, both on and off antiretroviral drugs, REE may be increased by approximately 10%.
What is root trust?
Root of Trust (RoT) is a source that can always be trusted within a cryptographic system. Because cryptographic security is dependent on keys to encrypt and decrypt data and perform functions such as generating digital signatures and verifying signatures, RoT schemes generally include a hardened hardware module.
What is secure element position?
Secure Elements are hardware components in which the credit card number can be stored, with limited interaction with the operating system other than to be used for mobile payments. The secure elements can exist either on the chip (embedded), or in SIMs, so it’s like using a smart card in your smartphone.
What is the difference between BMR and REE?
While BMR is a minimum number of calories required for basic functions at rest, RMR — also called resting energy expenditure (REE) — is the number of calories that your body burns while it’s at rest.
