Gimli: A cross-platform permutation

This paper presents Gimli, a 384-bit permutation designed to achieve high security with high performance across a broad range of platforms, including 64-bit Intel/AMD server CPUs, 64-bit and 32-bit ARM smartphone CPUs, 32-bit ARM microcontrollers, 8-bit AVR microcontrollers, FPGAs, ASICs without side-channel protection, and ASICs with side-channel protection.
Like other permutations with sufficiently large state sizes, Gimli can easily be used to build high-security block ciphers, tweakable block ciphers, stream ciphers, message-authentication codes, authenticated ciphers, hash functions, etc.
