What is the maximum level of encryption permissible on the Harris 7800W radio without external equipment?

The maximum level of encryption permissible on the Harris 7800W radio without the need for external equipment is AES 256 bit. This level of encryption ensures a high degree of security, making the communication robust against unauthorized access and various forms of interception. AES (Advanced Encryption Standard) is widely recognized for its effectiveness and is often used for securing sensitive and classified communications.

Using AES 256 bit encryption provides a strong encryption key that significantly enhances the security of the transmitted data, which is essential in military and sensitive operational environments. The choice of AES 256 bit as the maximum standard indicates that the radio is designed for high-security scenarios, allowing users to confidently conduct operations without the concern of data compromise due to insufficient encryption strength.

While other encryption levels like AES 128 and AES 192 are valid and secure, they do not match the robustness of AES 256 bit. RSA 2048 bit, on the other hand, is a different encryption algorithm that serves purposes distinct from symmetric encryption standards like AES, which is specifically utilized for encrypting data directly rather than for key exchange or digital signatures. Therefore, the highest level of encryption directly usable on the radios without additional equipment remains AES 256 bit.
