The radio side of things is quite well standardised around Mars actually.
The majority of missions now carry an Electra radio unit https://en.wikipedia.org/wiki/Electra_(radio) https://en.wikipedia.org/wiki/Electra_(radio)
The Electra radio implements the Consultative Committee for Space Data Systems (CCSDS) Proximity-1 Space Link Protocol (https://en.wikipedia.org/wiki/Proximity-1_Space_Link_Protocol https://en.wikipedia.org/wiki/Proximity-1_Space_Link_Protoco...) which is available online as PDFs, divided into three sections: Data Link Layer CCSDS 211.0-B https://public.ccsds.org/Pubs/211x0b6.pdf https://public.ccsds.org/Pubs/211x0b6.pdf ; Physical Layer CCSDS 211.1-B - https://public.ccsds.org/Pubs/211x1b4e1.pdf https://public.ccsds.org/Pubs/211x1b4e1.pdf ; and Coding and Synchronization Sublayer CCSDS 211.2-B - https://public.ccsds.org/Pubs/211x2b3.pdf https://public.ccsds.org/Pubs/211x2b3.pdf
The CCSDS provides full access to all their recommended standards on their website ( https://ccsds.org https://ccsds.org )
There are some recommended standards published regarding crypto and security: "Security Architecture for Space Data Systems" (CCSDS 351.0-M), "Space Data Link Security Protocol" (CCSDS 355.0-B) , "CCSDS Cryptographic Algorithms" (CCSDS 352.0-B), and others.
And to wrap up, they also have standards regarding deep space communications inside "Radio Frequency and Modulation Systems—Part 1: Earth Stations and Spacecraft" (CCSDS 401.0-B) https://public.ccsds.org/Pubs/401x0b31.pdf https://public.ccsds.org/Pubs/401x0b31.pdf which has been an active recommended standard for over 30 years now, so everything currently operating at Mars (NASA, ESA, and the China National Space Administration (CNSA) are all participating in CCSDS) is likely conforming pretty closely to the radio communications standards in CCSDS 401.0-B
Overall its a pretty amazing amount of detail provided by them, a real wealth of technical information regarding spacecraft operations and engineering.
