ملخص: The Portal Security Transaction Protocol (PSTP) is a new signature technology that adds signature semantics to one-time password technology. PSTP was developed to secure transactions in the financial services industry; however, PSTP may be applicable to signatures in other spaces. PSTP technology provides high signature strength of mechanism without requiring asymmetric key pairs deployed to client machines. PSTP provides cryptographic after-the-fact evidence of a transaction event in a secured log.
