What about this list of security options for BT Devices, including Re-Key Keylocking System good enough for GPS

I know that if you cannot support FIPS 128Bit on Unifier USB, Most likely the following profiles help! But i can help you make better asics

Good operational performance of all SiMD NANO related security function for Mouse Matrix core Arm Nano, Now i know that it is very likely you use a generic, very small processor & that Unifier USB needs a security profile & so does BlueTooth! RS

Bluetooth, Bolt (BT), Unifying Receiver: ICE-SSRTP

Observations of devices such as:

Logitech Bolt (ECDH AES GCM)
Amazons Keyboard & Mouse (AES Secure)

Logitech Unifying Receiver & Bluetooth (Varies);

Personally i forward ICE-SSRTP,
ICE-SSRTP is based on flexible encryption channels (1 to 7) & Wave banding (separate wave threads)

According to reports the Unifier USB was not compatible with 256Bit GCM ECDH,
Now i would observe that ICE-SSRTP has several options available that are competitive:

Multiple Sub-Banding (MP4, AC3, AC4, SBC, BT)

Improved AES,
CHACHA20-POLY1305,
GEA,
3DES

& Other RTP Classifications such as UDP & TCP & GRE
3G, 4G LTE & 5G Encoding.

So as follows, In principle 3 Sub-Band 64Bit AES/GCM/GEA/3DES; Offers quite a lot of security!

Now hold on! 64Bit/96Bit AES? <

Cypher Keys : 64Bit/96Bit/128Bit/192Bit/256Bit

AES,
CHACHA20_POLY1305,
GEA,
3DES, 5DES,

3/5 AES key DES ,
3/5 CHACHA20_POLY1305 key DES
3/5 GEA DES ,

3 Bands! Even 5 &
2 to 4 Keys CRT
&or
2 to 5 Timing Syncs

Yes this is ECDH & Time is involved; So who says 2 bands have the same moment to Sync?

In terms of lightweight security (Bluetooth ear-buds & other tiny things) :
64Bit AES/3DES/GEA with ICE-SSRTP Nonce makes perfect sense.

In Terms of heavier (in terms of ARM Core Phones & Network-boxes) :

Both the 64Bit Instruction-set & the 32Bit SiMD/NANO + AES-NE + Advance Crypto Instruction ACI,
96Bit/128Bit AES/3DES/GEA * 3 Packets per nonce ICE-SSRTP

In Terms of larger demands: With 64Bit/128Bit Instruction-set & the 32Bit SiMD/NANO/AVX128Bit+, + AES-NE + Advance Crypto Instruction ACI

96Bit * 5 /128Bit/256Bit/384Bit *3 AES/3DES/GEA * 3 Packets per nonce ICE-SSRTP
