Abstract
A public key cryptographic method based on groups of braids. The method employs a secret key defined by a representative s of a given braid S in a braid group G, a public key defined by a representative v of the braid T(S) converted from the braid S by an operator T, and an operation of verifying the equality of two braids, i.e. the equivalence of representatives of the two braids.
