Other Notation. ‌ The symbol is often used to denote the concatenation of two strings. For instance, a hash function H(k m) = H(k, m) gives the hash value of a message m computed under a key k. Functions denoted {0, 1}∗ G1 map an arbitrary-length binary message to an element of the group G1, and is of→ten used by hash functions to represent the mapping of a user identity to an elliptic curve integer point. {0, 1}k denotes a binary message that is k bits in length.
