What Does One-Time Password Specifications Mean?

One-time password specification (OTPS) is an ongoing policy for creating an access control mechanism for systems that rely on or work on one-time password-based authentication (where the password changes for each login, hence is only valid one time).

OTPS was first unveiled in 2005 by RSA Security for building information systems with strong security and authentication mechanisms.

Techopedia Explains One-Time Password Specifications

OTPS is primarily a suite security, which is developed using the joint effort of RSA and other security developers. The core objective behind OTPS is to facilitate the development and integration of OTP-based authenticating within information systems.

As of 2013, RSA has published seven different security standards that comply with OTPS:

· CT-KIP: Cryptographic Token Key Initialization Protocol

· OTP-CAPI: Microsoft CryptoAPI profile for One-time Password

· OTP-Kerberos

· OTP-TLS: One-time Password Specification for Transport Layer Security

· EAP-POTP: Protected One-time Password for EAP

· OTP-WSS-Token: Web Services Security One-time Password Token Profile

· OTP-PKCS: One-time Password for Public Key Cryptography System
