| Parameter set | Security model | Claimed NIST security level | Public key size (bytes) | Secret key size (bytes) | Ciphertext size (bytes) | Shared secret size (bytes) |
|---|---|---|---|---|---|---|
| BIKE1-L1-CPA | IND-CPA | 1 | 2542 | 3110 | 2542 | 32 |
| BIKE1-L3-CPA | IND-CPA | 3 | 4964 | 5788 | 4964 | 32 |
| BIKE1-L1-FO | IND-CPA | 1 | 2946 | 6460 | 2946 | 32 |

Implementation
- Source of implementation: https://bikesuite.org/additional.html
- Implementation version: BIKE-1 L1/3 with the BGF decoder (as defined in "QC-MDPC decoders with several shades of gray" at https://eprint.iacr.org/2019/1423)
- BIKE-1-FO L1/3 that matches BIKE's v3.2
- BIKE-1-CPA L1/3 that matches BIKE Round-1 (and BIKE v3.0) for backward compatibility
