Abstract
A cryptographic method and apparatus, including providing a public key that defines a multivariate polynomial mapping Q( ) over a finite field F, extracting a first vector Y of verification values from a message, computing over the first vector, using a processor, a digital signature X including a second vector of signature values such that application of the mapping to the digital signature gives a third vector Q(X) of output values such that each output value is equal to a corresponding element of a vector sum Y+aYover F, wherein Yis a shifted version of Y, and aεF, and conveying the message with the digital signature to a recipient for authentication using the public key. Related methods, systems, and apparatus are also described.
