摘要
Methods and systems for the authentication of accreditation or messages and of message signatures. Instead of using multiple accreditations and an iterative verification process, deep-level accreditation is adopted (high exponent p), and a number D between 0 and p-1 is drawn at random. The verification operations include calculation of the Dth power of the inverse accreditation B. The invention is used particularly for chip cards and more especially for bank cards. IMAGE
