Interleaved Prange: A New Generic Decoder for Interleaved Codes
, 2022 Due to the recent challenges in post-quantum cryptography, several new approaches for code-based cryptography have been proposed. For example, a variant of the McEliece cryptosystem based on interleaved codes was proposed. In order to deem such new settings secure, we first need to understand and analyze the complexity of the underlying problem, in ...

Non interleaving process algebra [PDF]
, 1993 We study a non interleaving subalgebra of a reduct of a model of ACP. The model discussed uses step bisimulation semantics. We can derive identities in this model with the help of the (interleaving) ACP calculus with multi-actions.

Interleaving based SCMA Codebook Design Using Arnold’s Cat Chaotic Map
Iraqi Journal of Information & Communication Technology, 2023 Non-orthogonal multiple access (NOMA) technology is a significant topic of the present 5G investigation. A possible NOMA approach is Sparse Code Multiple Access (SCMA), increasing next-generation communication's ability to handle multiple users. In SCMA,

Interleaving Shifted Versions of a PN-Sequence
Mathematics, 2021 The output sequence of the shrinking generator can be considered as an interleaving of determined shifted versions of a single PN -sequence. In this paper, we present a study of the interleaving of a PN-sequence and shifted versions of itself. We analyze
