1 Embedded TCP/IP-Security
2 Agenda What is security? A look into a security data sheet Symmetric vs. asymmetric cryptography TCP/IP security SSL/TLS CB ussl SSH CB ussh Demo Summary Page 2
3 What is security? ITU-T Recommendation X.805: Security architecture for systems providing end-to-end communications Security threats Destruction of information and other resources Corruption or modification of information Theft, removal or loss of information and other resources Disclosure of information Interruption of services Security dimensions: Security measures designed to address a particular aspect of network security Access control Authentication Non-repudiation Data confidentiality Communication security Data integrity Availability Privacy Page 3
4 Look into a security data sheet Page 4
5 Symmetric Cryptography Symmetric encryption = private key cryptography Source: The Globus Toolkit 4 Programmer's Tutorial, University of Chicago Algorithms Data Encryption Standard (DES) Triple DES (3DES) Advanced Encryption Standard (AES) Advantage: Low computational complexity Disadvantage: Communication partners share private key How can keys securely be exchanged?? Source: Wikipedia Page 5
6 Asymmetric Cryptography I Asymmetric encryption = public key cryptography Source: The Globus Toolkit 4 Programmer's Tutorial, University of Chicago Algorithms RSA: Security due to cost of factoring a product of two large prime numbers ElGamal Advantages: Public Key Private Key Private key never needs to be transmitted Provides a method for digital signatures Disadvantage: High computational complexity Source: Raj Jain, Washington University, Network security lectures on youtube Page 6
7 Asymmetric Cryptography II: Digital signatures and X.509 certificate authentication Applications: Message Integrity Non-repudiation Algorithms: Secure Hash (SHA) Message Digest (MD) Problem: To whom belongs the public key? Public key infrastructure (PKI) CA X.509 certificates Source: Hashing Algorithm Decryption Public Key CA Hash Hash Certification Authority (CA) Page 7
