KDDI: The world’s fastest cryptographic algorithm: “Rocca”
-Looking at the Beyond 5G / 6G era-
KDDI R & D Laboratories
University of HyogoOn November 9, we developed the encryption algorithm “Rocca” that supports “Beyond 5G / 6G communication that realizes high-speed, large-capacity communication.”
The processing speed is 138 Gbps, which is the fastest in the world.
Cryptographic algorithm “Rocca”:
The Rocca key length is 256 bits.
Integrate the authentication function,
Guarantee that the data has not been tampered with,
Developed “authenticated encryption”.
KDDI’s cryptographic algorithm “Rocca”:Rocca’s processing speed is 4.5 times faster than the US standard encryption algorithm “AES”.
Supports 100 Gbps:
Authenticated encryption algorithm with 256-bit key length.
It is said that it exceeded 100 Gbps for the first time.

“Rocca”: Beyond 5G / 6G high-speed cryptographic algorithm
-Achieved 138 Gbps with a key length of 256 bits-
Features of Rocca:
The main components are operations (including AES-NI) that can be processed at high speed on PCs and smartphone CPUs.
High speed is achieved by efficiently processing these in parallel (Fig. 1).
In addition, it is arranged in a structure that can ensure sufficient safety, achieving both high speed and safety.
KDDI Research, Inc.
University of Hyogo Graduate SchoolIt appeals that it has the processing performance required for Beyond 5G / 6G (the next generation of 5G / 6G).
Achievements this time:
It was recorded at the “28th annual Fast Software Encryption conference” (FSE2022), an international conference on cryptographic software implementation.
It will be announced in March 2022. Twice
Beyond 5G / 6G area:
Research and development is underway with the goal of communication speeds exceeding 100 Gbit / s.
The following three requirements are listed.
It is said that Rocca was developed as a cryptographic algorithm equipped with these.
(1) A cryptographic algorithm with similar processing performance is required to realize ultra-high-speed communication such as large-capacity video transmission.
(2) A key length of 256 bits is required to make it resistant to decoding by a quantum computer.
(3) The algorithm (authenticated encryption) can guarantee that the data has not been tampered with.
