Week13 presentation
- 1. How Encryption for Strong Security Works ・ PSTN Multi-Function Cipher Machine ・ Virtual private network (VPN) ・ SSL (Secure Sockets Layer) ・ RSA
- 2. PSTN Multi-Function Cipher Machine PSTN multi-function cipher machine enable the encryption and protection service of important call, fax and point-to-point data communication via public and/or private telephone network, to ensure the safety of transmission over lines, thereby effectively preventing leak loss from the transmission lines of sensitive information. PSTN multi-function cipher machine consists of general purpose key management device, Key Distribution Center and cipher machine. Two ways (online and offline) of key management are supported, general purpose key management device creates key, and distributes cipher algorithm and key offline; the key distribution center/console is able to distribute key online.
- 3. Virtual private network (VPN) A virtual private network (VPN) is a computer network that uses a public telecommunication infrastructure such as the Internet to provide remote offices or individual users with secure access to their organization's network. It aims to avoid an expensive system of owned or leased lines that can be used by only one organization.
- 4. SSL (Secure Sockets Layer) ● SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser.
- 5. RSA ● RSA(which stands for Rivest, Shamir and Adleman who first publicly described it) is an Internet encryption and authentication system that uses an algorithm developed in 1977.
