It generally refers to algorithms in symmetric cryptography specifically designed to be efficient in new advanced cryptographic protocols. These contexts include zero-knowledge (ZK) proofs, secure multiparty computation (MPC) and (fully) homomorphic encryption (FHE) environments. It encompasses everything from arithmetization-oriented hash functions to homomorphic encryption-friendly stream ciphers.[\/vc_column_text][\/us_vwrapper][\/vc_column][\/vc_row][vc_row height=”medium” color_scheme=”alternate” us_bg_overlay_color=”#f5f5f5″ us_shape_show_top=”1″ us_shape_top=”triangle-2″ us_shape_color_top=”#ffffff” us_shape_show_bottom=”1″ us_shape_color_bottom=”#ffffff” us_shape_flip_bottom=”1″][vc_column][us_separator][vc_row_inner][vc_column_inner width=”5\/6″][vc_custom_heading text=”STAP Zoo” font_container=”tag:h2|text_align:left|color:%23219ebc” google_fonts=”font_family:ABeeZee%3Aregular%2Citalic|font_style:400%20regular%3A400%3Anormal”][vc_column_text css=”%7B%22default%22%3A%7B%22color%22%3A%22%231a1a1a%22%7D%7D”]We present a collection of proposed symmetric primitives fitting the STAP description and keep track of recent advances regarding their security and consequent updates. These may be filtered according to their features; we categorize them into different groups regarding primitive-type (block cipher<\/a>, stream cipher<\/a>, hash function<\/a> or PRF<\/a>) and use-case (FHE<\/a>, MPC<\/a> and ZK<\/a>).<\/p>\n

For each STAP-primitive, we provide a brief overview of its main cryptographic characteristics, including:<\/p>\n
