Bài toán xác thực
Trường Checksum thực hiện kết hợp khóa và gói tin thành một gói tin chứng thực MAC (Message Authenticateion Code). Sau khi thực hiện Sender sẽ gửi MAC và gói tin tới Receiver trên một kênh không bảo mật. Receiver sau khi nhận được MAC và hàm băm của Sender sẽ thực hiện quá trình băm như của Sender để tạo ra một MAC khác. Sau đó Receiver sẽ thực hiện so sánh MAC của Sender và MAC của mình. Nếu giống nhau thì dữ liệu là toàn vẹn, nếu khác nhau thì dữ liệu không toàn vẹn. ...

Network Security
Security Attack: Any action that compromises the security of information. Security Mechanism: A mechanism that is designed to detect, prevent, or recover from a security attack. Security Service: A service that enhances the security of data processing systems and information transfers. A security service makes use of one or more security mechanisms.

Access Control Models: From the real-world to trusted computing
We have looked at protocols for distributing and establishing keys used for authentication and confidentiality But who should you give these keys to? Who should you trust? What are the rules governing when to and not to give out security credentials In this lecture, we will look at the broad area of secure and trusted systems We will focus on access control models These methods are often used to abstract the requirements for a computer system But, they hold for general systems where security is a concern (e.g. networks, computers, companies…) ...

Authentication Methods: From Digital Signatures to Hashes
We have looked at confidentiality services, and also examined the information theoretic framework for security. Confidentiality between Alice and Bob only guarantees that Eve cannot read the message, it does not address: Is Alice really talking to Bob? Is Bob really talking to Alice? In this lecture, we will look at the following problems: Entity Authentication: Proof of the identity of an individual Message Authentication: (Data origin authentication) Proof that the source of information really is what it claims to be Message Signing: Binding information to a particular entity Data Integrity: Ensuring that information has not been altered by unknown entities ...
