New symmetric encryption algorithms?

Question

C++ / C#

Tell me if there is something new?
ps GOST, EAS do not offer)

Answer 1

Good afternoon,
and for what specific task are you interested?
there are many symmetric ciphers.
en.wikipedia.org/wiki/%D0%A1%D0%B8%D0%BC%D0%BC%D0%...
for example =)
Or is something specific interested in properties? algebraic structures?

Answer 2

The algorithms themselves are interesting, for implementation in parallelization on GPUs, coprocessors, and for building nano-optical encryption systems.
