Document Publication: LLA and LLE: Are You Really Secure?
SAFECOM Members,
SAFECOM and the National Council of Statewide Interoperability Coordinators (NCSWIC) are pleased to announce publication of the Link Layer Authentication (LLA) and Link Layer Encryption (LLE):  Are You Really Secure?  whitepaper, developed by the Joint SAFECOM/NCSWIC Project 25 (P25) User Needs Working Group (UNWG) members and supported by the Cybersecurity and Infrastructure Security Agency (CISA).  The whitepaper summarizes the difference between LLA and LLE, and emphasizes the need for encryption in the P25 environment.  While both LLA and LLE sound similar and improve Project 25 security, they serve different purposes and are in different stages of development and adoption.
This document would not have been possible without your help, and we sincerely thank you.  We are grateful for your contributions and look forward to working with you on future products.
We encourage you to share the publication blog post with your colleagues and others who might be interested in this document.
Thank you again for your continued support of this document.
