In [computing](/source/computing), a '''secure environment''' is any <!--environment-->system which implements the controlled [storage](/source/computer_data_storage) and use of information.  In the event of [computing](/source/computing) [data loss](/source/data_loss), a secure environment is used to protect personal or confidential data. It may also be known as a trusted execution environment (TEE).<ref name="b970">{{cite journal | last1=Kumar | first1=Sandeep | last2=Moolchandani | first2=Diksha | last3=Sarangi | first3=Smruti R. | title=Hardware-assisted mechanisms to enforce control flow integrity: A comprehensive survey | journal=Journal of Systems Architecture | publisher=Elsevier BV | volume=130 | year=2022 | issn=1383-7621 | doi=10.1016/j.sysarc.2022.102644 | article-number=102644}}</ref><ref name="d880">{{cite web | title=Basics of Trusted Execution Environments (TEEs): The Heart of Confidential Computing – Confidential Computing Consortium | website=Confidential Computing Consortium | date=2024-03-13 | url=https://confidentialcomputing.io/2024/03/13/basics-of-trusted-execution-environments-tees-the-heart-of-confidential-computing/ | access-date=2025-08-11}}</ref>

Often, secure environments employ [cryptography](/source/cryptography) as a means to protect information. This is typically used for processing confidential or restricted information.<ref name="p115">{{cite book | last1=Lee | first1=Changhoon | last2=Seigneur | first2=Jean-Marc | last3=Park | first3=James J.

Some secure environments employ [cryptographic hashing](/source/Cryptographic_hash_function), simply to verify that the information has not been altered since it was last modified.
