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, stream cipher, hash function or PRF) and use-case (FHE, MPC and ZK).

For each STAP-primitive, we provide a brief overview of its main cryptographic characteristics, including:

• Basic general information: designers, year, conference/journal where it was first introduced and reference.
• Basic cryptographic properties such as description of the primitive (and relevant diagrams when applicable), use-case and proposed parameter sets.
• Relevant known attacks/weaknesses.
• Properties of its best hardware implementation.

When applicable, we also mention connections and relations between different designs.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/6″][/vc_column_inner][/vc_row_inner][us_separator size=”large”][/vc_column][/vc_row][vc_row css=”%7B%22default%22%3A%7B%22background-color%22%3A%22_header_middle_text%22%7D%7D”][vc_column][vc_custom_heading text=”News” font_container=”tag:h2|text_align:left|color:%23219ebc” google_fonts=”font_family:ABeeZee%3Aregular%2Citalic|font_style:400%20regular%3A400%3Anormal” css=”%7B%22default%22%3A%7B%22color%22%3A%22_content_bg_alt%22%7D%7D”][us_separator size=”small”][us_grid taxonomy_category=”news” pagination=”infinite” items_layout=”1474″ items_valign=”1″ columns=”1″ overriding_link=”%7B%22url%22%3A%22%22%7D”][us_separator size=”small”][/vc_column][/vc_row][vc_row height=”small” color_scheme=”alternate” us_bg_overlay_color=”#ffffff” us_shape_show_top=”1″ us_shape_color_top=”#ffffff” us_shape_flip_top=”1″ css=”%7B%22default%22%3A%7B%22background-color%22%3A%22_header_middle_bg%22%7D%7D”][vc_column link=”%7B%22url%22%3A%22%22%7D” css=”%7B%22default%22%3A%7B%22background-color%22%3A%22%23ffffff%22%7D%7D”][vc_row_inner content_placement=”middle” css=”%7B%22default%22%3A%7B%22background-color%22%3A%22%23ffffff%22%2C%22border-style%22%3A%22solid%22%2C%22border-color%22%3A%22%231a1a1a%22%7D%7D”][vc_column_inner width=”1/6″][/vc_column_inner][vc_column_inner us_bg_overlay_color=”#ffffff” link=”%7B%22url%22%3A%22%22%7D” css=”%7B%22default%22%3A%7B%22border-radius%22%3A%225px%22%2C%22border-style%22%3A%22double%22%2C%22border-left-width%22%3A%2255%22%2C%22border-top-width%22%3A%2244%22%2C%22border-bottom-width%22%3A%2255%22%2C%22border-right-width%22%3A%2255%22%2C%22border-color%22%3A%22%23023047%22%2C%22box-shadow-blur%22%3A%223px%22%2C%22box-shadow-color%22%3A%22%23023047%22%7D%7D” width=”2/3″][us_separator size=”small”][vc_custom_heading text=”STAP Lounge” font_container=”tag:h2|font_size:42|text_align:center|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”]
