Kyber512 wrapper class providing high-level KEM operations This class wraps the low-level WASM module to provide a user-friendly interface for Kyber512 operations with automatic …

Learn about the Kyber512 post-quantum algorithm in ByteHide Storage. NIST Level 1 security with excellent performance characteristics for high-frequency operations.

A sample run of Kyber512 shows that the public key size is 800 bytes, the secret key is 1,632 bytes, and the key exchange sizes of 1568 bytes (for mutual authentication):

Dec 23, 2020 · Kyber is an IND-CCA2-secure key encapsulation mechanism (KEM), whose security is based on the hardness of solving the learning-with-errors (LWE) problem over …

Apr 25, 2025 · Kyber512 (K=2): Offers NIST Level 1 security (equivalent to AES-128). It has the smallest key and ciphertext sizes, and the best performance among the three parameter sets.

By incorporating these features, Kyber provides a higher level of security compared to traditional key pair generation methods, especially in the context of future quantum computing threats.

Overall a KEM allows a symmetric key to be passed using public key methods. In this case, Alice will generate her key pair of a public key (\ (pk\)) and a private key (\ (sk\)). She then passes …

Broadly speaking, this means Kyber512 is claimed to be at least as hard to break as AES-128.

In this case, we see a 32-byte secret (private) key size for P256, and 64 bytes for the public key (as it has an x- and y-co-ordinate value) and then another byte added to identify the type of …
