Encryption is a technique used to protect data and transmissions by encoding them in a way that only authorized parties can access. There are two main types: symmetric encryption uses a single secret key for encryption and decryption, while asymmetric encryption uses two keys - a public key to encrypt and a private key to decrypt. Symmetric encryption is faster but less secure as it relies on secure key exchange, while asymmetric encryption uses separate keys and is more secure though computationally slower. Digital certificates verify the identity of websites, machines, or devices and are issued by certificate authorities to facilitate secure transactions online.

E-commerce- Security & Encryption
This document discusses dimensions of e-commerce security including integrity, non-denial, authenticity, confidentiality, privacy and availability. It also outlines security threats such as malicious code, phishing, hacking and credit card fraud. Finally, it describes various technology solutions for protecting internet communications through encryption, securing communication channels using SSL and VPNs, protecting networks with firewalls, and protecting servers and clients with access controls and anti-virus software.
Demonstration of secure socket layer(synopsis)
The document discusses Secure Socket Layer (SSL) protocol and how it provides security for internet transactions. It explains that SSL uses cryptography, digital signatures, and certificates to provide confidentiality, message integrity, and authentication. It details how SSL works, including the handshake protocol for authentication and key exchange, the record protocol for encrypting data transfer, and SSL roles/elements like certificates and certificate authorities. The goal of the project is to implement a client and server that can securely communicate and transfer data using the SSL protocol.
How encryption works
Encryption uses keys to scramble files and make them hidden. There are two main encryption systems: symmetric key encryption which uses the same key shared between sender and receiver, and public key encryption which uses a secret key known only to the user and a public key to encrypt files. Common encryption protocols are SSL/TLS which encrypt web browser data during transmission between clients and servers. Encryption systems also use hashing algorithms to change data into hashed values.
Chapter 08
This chapter discusses commonly used cryptographic systems and how cryptography is applied to make computer systems more secure. It covers symmetric and asymmetric encryption algorithms, digital signatures, certificates, and encryption utilities like PGP and GPG. Specific techniques covered include DES, Triple DES, AES, SSL, Kerberos, VPNs, and how tools like SSH, RPM, and encrypted file systems provide additional security.
Ssl and tls
Transport Layer Security (TLS) is the successor to the Secure Sockets Layer (SSL) protocol. TLS ensures privacy and security between communicating applications and users on the internet by preventing eavesdropping, tampering, and message forgery. It works by having the client and server negotiate a cipher suite and protocol version to use to securely transmit encrypted messages. This establishes a secure channel over an unsecured network like the internet to provide confidentiality, integrity, and authentication of communications.

Overview of cryptography
This document provides an overview of cryptography. It discusses that cryptography is the practice of secure communication in the presence of others. The purpose of cryptography is to defend against hackers and industrial espionage while securing e-commerce, bank accounts, intellectual property, and avoiding liability. Cryptography provides authentication, privacy, integrity, and non-repudiation. Encryption converts plain text to cipher text using a key while decryption converts cipher text to plain text. Common cryptographic algorithms are secret key cryptography, public key cryptography, and hash functions. Secret key cryptography uses a private key for encryption while public key cryptography uses a public key exchanged over an insecure channel. Hash functions produce a checksum of data. AES encryption is now commonly used and
online game over cryptography
Cryptography involves encrypting data using mathematical algorithms and decrypting it back to plaintext. Encryption scrambles data into ciphertext while decryption returns it to readable text. Conventional cryptography uses a single key for both functions but public key cryptography uses different keys for encryption and decryption, eliminating the need to share secret keys. Hybrid cryptography combines the strengths of both by using asymmetric keys to distribute a symmetric session key for bulk encryption. Cryptanalysis aims to break secure communication while steganography hides messages within innocent-looking files like images and audio.

ENCRYPTION.pptx
- 1. ENCRYPTION
- 2. DEFINITION Encryption is a technique used to protect data stored on computer systems and data transmitted via computer networks, including the Internet.
- 4. Symmetric encryption What is Symmetric Encryption? Symmetric encryption is a type of encryption where only one key (a secret key) is used to both encrypt and decrypt electronic data. The entities communicating via symmetric encryption must exchange the key so that it can be used in the decryption process.
- 6. What is Asymmetric cryptography? Asymmetric cryptography, also known as public-key cryptography, is a process that uses a pair of related keys -- one public key and one private key -- to encrypt and decrypt a message and protect it from unauthorized access or use.
- 8. Key Differences Symmetric Encryption Asymmetric Encryption Size of cipher text Smaller cipher text compares to original plain text file. Larger cipher text compares to original plain text file. Data size Used to transmit big data. Used to transmit small data. Resource Utilization Symmetric key encryption works on low usage of resources. Asymmetric encryption requires high consumption of resources. Key Lengths 128 or 256-bit key size. RSA 2048-bit or higher key size. Security Less secured due to use a single key for encryption. Much safer as two keys are involved in encryption and decryption. Number of keys Symmetric Encryption uses a single key for encryption and decryption. Asymmetric Encryption uses two keys for encryption and decryption Techniques It is an old technique. It is a modern encryption technique. Confidentiality A single key for encryption and decryption has chances of key compromised. Two keys separately made for encryption and decryption that removes the need to share a key. Speed Symmetric encryption is fast technique Asymmetric encryption is slower in terms of speed. Algorithms RC4, AES, DES, 3DES, and QUAD. RSA, Diffie-Hellman, ECC algorithms.
- 9. What is an SSL? SSL stands for Secure Sockets Layer and, in short, it's the standard technology for keeping an internet connection secure and safeguarding any sensitive data that is being sent between two systems, preventing criminals from reading and modifying any information transferred, including potential personal details. The two systems can be a server and a client (for example, a shopping website and browser)
- 10. What is TLS? TLS (Transport Layer Security) is just an updated, more secure, version of SSL. TLS is actually just a more recent version of SSL. It fixes some security issue which are in the earlier SSL protocols.
- 11. SSL SSL (Secure Socket Layer) is less secured as compared to TLS(Transport Layer Security). TLS TLS (Transport Layer Security) provides high security. SSL is less reliable and slower. TLS is highly reliable and upgraded. It provides less latency.
- 12. What is Digital Certificates? A digital certificate is basically a unique piece of code or a large number that says that the Webserver is trusted by an independent source known as a certificate authority. The certificate authority acts as a middleman that both computers trust. It confirms that each computer is in fact who it says it is, and then provides the public keys of each computer to the other.
- 13. How are digital certificates used? Digital certificates are used in the following ways: •Credit and debit cards use chip-embedded digital certificates that connect with merchants and banks to ensure that the transactions performed are secure and authentic. •Digital payment companies use digital certificates to authenticate their automated teller machines, kiosks and point-of-sale equipment in the field with a central server in their data center. •Websites use digital certificates for domain validation to show they are trusted and authentic.
