The Oribatida v1.3 Family of Lightweight Authenticated Encryption Schemes
2021
Journal of Mathematical Cryptology
Permutation-based modes have been established for lightweight authenticated encryption, as can be seen from the high interest in the ongoing NIST lightweight competition. However, their security is upper bounded by O(σ 2/2 c ) bits, where σ are the number of calls and c is the hidden capacity of the state. The development of more schemes that provide higher security bounds led to the CHES'18 proposal Beetle that raised the bound to O(rσ/2 c ), where r is the public rate of the state. While
