What are the security vulnerabilities of this authentication scheme?

They claimed that their scheme provides security against replay attack, password guessing attack, insider attack and impersonation attack. This paper demonstrates that Yang et al.’s scheme is vulnerable to impersonation attack and fails to provide essential features to satisfy the needs of a user.

Are smart cards secure?

A smart card is a safe place to store valuable information such as private keys, account numbers, passwords, or personal information. It’s also a secure place to perform processes that one doesn’t want to be exposed to the world, for example, performing a public key or private key encryption.

What type of authentication do smart cards use?

The smart card stores a user’s public key credentials and a personal identification number (PIN), which acts as the secret key to authenticate the user to the smart card. A smart card enhances security—you can’t gather user details (such as a PIN) by tampering with these cards.

Can smart cards be hacked?

They can be used by themselves or with a PIN number in a two-factor authentication system. A number of researchers have found ways to hack smart cards by tampering with the microchip using light from camera flashbulbs and radio signals.

What are some examples of security concerns for data that is accessed remotely *?

Five Remote Access Security Risks And How To Protect Against Them

1. Weak remote access policies.
2. A deluge of new devices to protect.
3. Lack of visibility into remote user activity.
4. Users mixing home and business passwords.
5. Opportunistic phishing attempts.

What are the benefits of this authentication scheme?

There are numerous advantages of authentication systems which are used to identify the user of a home, ATM or a security clearance computer system. The main purpose of these systems is to validate the user’s right to access the system and information, and protect against identity theft and fraud.

What is smart card security?

Smart cards are portable, personal security devices that can securely carry sensitive information, enable secure transactions, validate an individual’s identity within a secure system, and verify that an information requestor is authorized to access the information carried on the card.

What is smart card in information security?

A smart card is a physical card that has an embedded integrated chip that acts as a security token. Smart cards are designed to be tamper-resistant and use encryption to provide protection for in-memory information.

What are the uses of smart card?

Smart cards can provide personal identification, authentication, data storage, and application processing. Applications include identification, financial, mobile phones (SIM), public transit, computer security, schools, and healthcare.

Can someone hack your credit card?

Hackers can steal credit and debit card information in a variety of ways, using both online and offline methods.

What are the risks of remote access?

Remote access threats

• lack of physical security controls – creating a risk of device loss or theft.
• eavesdropping – as information travels over the public internet.
• unauthorised access to systems or data – perhaps overlooking the screen.
• monitoring and manipulation of data – if someone gains access to the device.
