Anubis

Anubis (/əˈnuːbᵻs/ or /əˈnjuːbᵻs/;Ancient Greek: Ἄνουβις) is the Greek name of a god associated with mummification and the afterlife in ancient Egyptian religion, usually depicted as a canine or a man with a canine head. Archeologists identified the sacred animal of Anubis as an Egyptian canid, that at the time was called the golden jackal, but recent genetic testing has caused the Egyptian animals to be reclassified as the African golden wolf.

Like many ancient Egyptian deities, Anubis assumed different roles in various contexts. Depicted as a protector of graves as early as the First Dynasty (c. 3100 – c. 2890 BC), Anubis was also an embalmer. By the Middle Kingdom (c. 2055 – 1650 BC), Anubis was replaced by Osiris in his role as Lord of the underworld. One of his prominent roles was as a god who ushered souls into the afterlife. He attended the weighing scale during the "Weighing of the Heart," in which it was determined whether a soul would be allowed to enter the realm of the dead. Despite being one of the most ancient and "one of the most frequently depicted and mentioned gods" in the Egyptian pantheon, Anubis played almost no role in Egyptian myths.

Anubis (cipher)

Anubis is a block cipher designed by Vincent Rijmen and Paulo S. L. M. Barreto as an entrant in the NESSIE project, a former research program initiated by the European Commission in 2000 for the identification of new cryptographic algorithms. Although the cipher has not been included in the final NESSIE portfolio, its design is considered very strong, and no attacks have been found by 2004 after the project had been concluded. The cipher is not patented and has been released by the designers for free public use.

Anubis operates on data blocks of 128 bits, accepting keys of length 32N bits (N = 4, ..., 10). It is designed as a substitution-permutation network, which bears large similarity to Rijndael. Like KHAZAD, designed by the same authors and also submitted to NESSIE, it uses involutions for the various operations. An involution is an operation whose inverse is the same as the forward operation. In other words, when an involution is run twice, it is the same as performing no operation. This allows low-cost hardware and compact software implementations to use the same operations for both encryption and decryption. Both the S-box and the mix columns operations are involutions. Although many involutional components can make a cipher more susceptible to distinguishing attacks exploiting the cycle structure of permutations within the cipher, no attack strategy for the Anubis cipher has been presented.

Aeneas

In Greco-Roman mythology, Aeneas (/ᵻˈniːəs/;Greek: Αἰνείας, Aineías, possibly derived from Greek αἰνή meaning "praised") was a Trojan hero, the son of the prince Anchises and the goddess Venus (Aphrodite). His father was the second cousin of King Priam of Troy, making Aeneas Priam's second cousin, once removed. He is a character in Greek mythology and is mentioned in Homer's Iliad. Aeneas receives full treatment in Roman mythology, most extensively in Virgil's Aeneid where he is an ancestor of Romulus and Remus. He became the first true hero of Rome.

Greek myth and epos

Homeric Hymn to Aphrodite

The story of the birth of Aeneas is told in the "Hymn to Aphrodite," one of the major Homeric Hymns. Aphrodite has caused the other gods, especially Zeus, to fall in love with mortal women. In retaliation, Zeus puts desire in her heart for Anchises, who is tending his cattle among the hills near Mount Ida. When Aphrodite sees him she is smitten. She adorns herself as if for a wedding among the gods and appears before him. He is overcome by her beauty, believing that she is a goddess, but Aphrodite identifies herself as a Phrygian princess. After they make love, Aphrodite reveals her true identity to him and Anchises fears what might happen to him as a result of their liaison. Aphrodite assures him that he will be protected, and tells him that she will bear him a son to be called Aeneas. However, she warns him that he must never tell anyone that he has lain with a goddess. When Aeneas is born, Aphrodite takes him to the nymphs of Mount Ida. She directs them to raise the child to age five, then take him to Anchises. According to other sources, Anchises later brags about his encounter with Aphrodite, and as a result is struck in the foot with a thunderbolt by Zeus. Thereafter he is lame in that foot, so that Aeneas has to carry him from the flames of Troy.
