Which standard is referred to by the acronym AES?

The acronym AES stands for Advanced Encryption Standard. This is a widely used symmetric encryption algorithm that is fundamental in securing data for various applications, including telehealth services within Veterans Affairs. AES was established as a federal standard in the United States and is recognized for providing a high level of security by using key sizes of 128, 192, or 256 bits.

The importance of AES in the context of telehealth is particularly notable as it ensures that sensitive patient information is protected during transmission and storage. This standard's widespread acceptance and use make it essential for complying with regulations regarding data security and privacy, such as HIPAA.

In contrast to the other options, the Automated Encryption System, Advanced Electronic Security, and Audio Engineering System do not reflect the universally recognized standard for encryption established by the National Institute of Standards and Technology (NIST). AES is the only correct reference among the choices provided regarding encryption methods used to safeguard data in various sectors, including medical and telehealth applications.
