I am very curious about what 'LIGHTWEIGHT' cryptography is defined as. I am also dubious about anyone that claims to have 'absolute world-leading cryptographers' since many strong cryptographers are quietly employed by intelligence agencies and most others are academics.

Also, since we are being pedantic, SHA-3/Keccak is an NIST standard, which is a federal agency of the United States.

I'm not an expert in the field, but there certainly have been efforts here and there to make "lightweight" crypto that needs little computational resources (and therefore battery power). One example would be KASUMI[0].
