Motorola Removes ADP Encryption as Included Option from Radios
Tuesday, November 07, 2017 | Comments

Motorola Solutions chose to remove the Advanced Digital Privacy (ADP) encryption feature as an included option from all subscriber models.

The announcement followed a Project 25 (P25) Compliance Assessment Program (CAP) encryption requirements compliance assessment bulletin (CAB) published earlier this year that aimed to stop manufacturers from providing subscriber units with a non-P25 standard encryption without also including P25 standard Advanced Encryption Standard (AES) 256 encryption.

Motorola Solutions and four other two-way radio vendors had products on a noncompliant list after the CAB was released. “Each one worked with OIC (Office for Interoperability and Compatibility) to make their equipment compliant,” said Sridhar Kowdley, P25 CAP program manager for the Department of Homeland Security (DHS) Science and Technology (S&T) Directorate.

"In order to reduce confusion on this complex topic and ensure continued compliance of our portfolio with the Project 25 Compliance Assessment Program's Encryption Requirements Compliance Assessment Bulletin, Motorola Solutions will remove the Advanced Digital Privacy (ADP) feature as an included option from all subscriber models on or before June 30, 2017," said Claudia Rodriquez, Motorola corporate vice president, devices, in a letter to DHS that was only recently made public. 

DHS made available correspondence from each of the five P25 manufacturers. The letters explain the process each manufacturer is using to bring its equipment into compliance with the encryption requirements CAB and the process customers should follow to ensure the equipment they purchase or have purchased is P25 CAP compliant.

“The problem we have with encryption is there is a nonstandard encryption being offered by some manufacturers that is making interoperability for those choosing encryption nonstandard again,” said Chief Gerry Reardon, chairman of the P25 CAP advisory panel (AP) in February before the CAB was released. “The AP believes that is the biggest impediment to interoperability right now.”

The CAB was released in March, and vendors have taken steps to inform customers about upgrading radios to become compliant with the new requirements. Radios that are not CAP certified might not be eligible to be purchased with grant funds.

I think this is kinda stupid because any competent entity that may need to interface with public-safety communications should know to specify Advanced Encryption Standard (AES) in their request for proposals (RFP) just like any grant for interoperable comms should specify AES encryption if needed.

But I guess there are a lot of inept public-safety agency comms managers, consultants and public-safety sector sales people out there.

Advanced Digital Privacy (ADP) filled a niche.
