Secure Socket Layer
- 1. “Secure Socket Layer” Project Presentation by: Dwiti Gajab Mihir Trivedi Aman Chaurasia 05/26/12 1
- 2. Contents: Cryptography and Secure Socket Layer (SSL) Establishment of Secured connection for “Encryption” Briefing on Asymmetric Encryption algorithms 05/26/12 2
- 3. Cryptography: Security and Integrity Encryption helps in achieving this. SSL is one such type of protocols. Its two main functions are: Encryption Identification 05/26/12 3
- 6. Few terms: Certificate: - It is used to authenticate the website. - Issued by Certificate Authority (CA). - Mainly contains: Public Key Digital Signature Hashing: - It is a process that compresses text to a single number. - Used in a certificate and in SSL handshaking. 05/26/12 6
- 7. Data Transfer: Asymmetric Data Transfer - Used in handshaking - Two Keys are involved: Public Key: It is used to encrypt. Private Key: It is used to decrypt. Symmetric Data Transfer Used in application data transfer. Same key is used in encryption & decryption. 05/26/12 7
- 9. Encryption Algorithms: Computers agree how to encrypt ! A B Key Cipher Hash Key Cipher Hash RSA DES HAC- MD5 RSA DES HAC- MD5 Diffie Hellman Triple DES HMAC- SHA Diffie Hellman Triple DES HMAC- SHA AES AES RC4 RC4 05/26/12 9
