Sike is an isogeny-based key encapsulation suite based on pseudo-random walks in supersingular isogeny graphs, that was submitted to the nist standardization process on post-quantum cryptography. Smallest public key size. Key compression has become almost free.
No decryption error, gaussians, rejection sampling, etc. Generic attacks are Γ’β¬Β¦ In this work, we present the fastest practical implementation of sike, targeting the platform cortex-m4 based on the armv7-m architecture. 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 point. Smallest public key size straightforward parameter selection no decryption error, gaussians, rejection sampling, etc. Generic attacks are well understood The exact values in these ranges depend on the choice of parameters, while the sizes of public keys and ciphertexts are unchanged (compression reduces them by about 40%, e. g. , a sikep434 public key is Γ’β¬Β¦

This compact-ness is essential for seamless integration Γ’β¬Β¦
