Apr 10, 2024 · This website will be used by the BIKE team as its official communication media. BIKE is a code-based key encapsulation mechanism based on QC-MDPC (Quasi-Cyclic …

Oct 4, 2022 · Algorithm type: Key encapsulation mechanism. Main cryptographic assumption: QC-MDPC (Quasi-Cyclic Moderate Density Parity-Check).

This package is an "Additional Optimized" implementation of the Key Encapsulation Mechanism (KEM) BIKE. It is developed and maintained solely by the DGK team that consists of Nir …

It has three security levels: Bike-128, Bike-192 and Bike-256. While Kyber-512 has a public key of 800 bytes, Bike128 uses a 1,541-byte public key. With the public key, Kyber512 has a key size …

The selection is made either with the flag specified during key generation or by matching the size of the imported data with the different lc_bike_*_load API calls.

BIKE can use different decoders without affecting interoperability. The decoder must be implementable in constant-time to avoid side-channel attacks, and its DFR must be low …

Jul 1, 2021 · This note discusses the technical considerations that are required for avoiding Property 1 in the context of BIKE, with methods to bind the errors vector to a specific public key.

Instead of (EC)DHE, a post-quantum public key cryptosystem or KEM with ephemeral keys, such as BIKE, QC-MDPC KEM or LEDA, can be used to transport initial key shares to provide post …
