The use of one-time password (OTP) has ushered new life into the existing authentication protocols used by the software industry. It introduced a second layer of security to the traditional username-password authentication, thus coining the term, two-factor authentication. One of the drawbacks of this protocol is the unreliability of the hardware token at the time of authentication. This paper proposes a simple backup key model that can be associated with the real world applications'user database, which would allow a user to circumvent the second authentication stage, in the event of unavailability of the hardware token. © Published under licence by IOP Publishing Ltd.

Backup key generation model for one-time password security protocol

IOP Conference Series: Materials Science and Engineering

Identifying and validating the user is a major concern in a heterogeneous network domain. Conventional algorithms and mechanisms could authenticate the users/messages, but with certain vulnerabilities. This paper analyzes the vulnerabilities and downsides of some present-day authentication mechanisms that are being used and proposes an authentication mechanism that cannot be bypassed easily. The proposed mechanism incorporates multi-factor authentication and validates the user based on a username, a password, a security question which is sent to the user via Short-Message-Service (SMS), and a security pin (if necessary). List of security questions posed to the end-user makes the proposed mechanism stronger and protect the system from security breaches by an unknown user to guess the answer. © Springer Nature Switzerland AG 2020.

Abstract Voice over Internet Protocol (VoIP) is a family of technologies for the transmission of voice over Internet. Voice is converted into digital signals and transmitted as data packets. The Session Initiation Protocol (SIP) is an IETF protocol for VoIP and other multimedia. SIP is an application layer protocol for creating, modifying and terminating sessions in VoIP communications. Since SIP is a more flexible and simple protocol, it is quite easy to add features to it. Distributed Denial of Service Attack (DDoS) floods the server with numerous requests from various hosts. Hence, the legitimate clients will not be able to get their intended services. A major concern in VoIP and almost in all network domains is availability rather than data consistency. Most of the surviving techniques could prevent VoIP network only after collision. This paper proposes a Recurrence Quantification based approach to detect and prevent VoIP from a DDoS attack. This model detects the attack at an earlier stage and also helps to prevent from further attacks. In addition, this techniques enables the efficient utilization of resources. QUALNET has been used to simulate the operation of the proposed technology.
