Cryptography Methodologies
From the last several years data and Security has become a main concern for anyone who connected to the internet. Data security prevents any modification in our data and ensures that our data is only accessible by the intended receiver. We have redeveloped methods and algorithm to achieve this level of security. Cryptography Is a technique for securing data, information and communication using some algorithms that make the data unreadable for human eye. We can decrypt the data using algorithm that is predefined by the sender. Devendra Kumar Meena | Dr. A.

Cryptography
Cryptography is the practice and study of hiding information. It involves encrypting plain text into unintelligible cipher text using an algorithm or key, and decrypting cipher text back into plain text. There are two main types of cryptography: symmetric key cryptography which uses the same key to encrypt and decrypt, and asymmetric key cryptography which uses different keys. Cryptography improves security, keeps communications private, and ensures privacy by encoding messages in a way that can only be read by those possessing the decryption key.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

- 7. TYPES OF CRYPTOGRAPHY CRYPTOGRAPHY SYMMETRIC KEY CRYPTOGRAPHY ASYMMETRIC KEY CRYPTOGRAPHY
- 8. SYMMETRIC KEY CRYPTOGRAPHY Encryption Decryption Cipher Text Sender Receiver Secret Key * Sender & receiver uses same key & an encryption/decryption algorithm to encrypt/decrypt data. i.e. the key is shared.
- 9. ASYMMETRIC KEY CRYPTOGRAPHY Encryption Decryption Cipher Text Sender Receiver Public Key * Sender & receiver uses different keys for encryption & decryption namely Public & Private respectively. Private Key
- 10. BASIC TERMS • CIPHER • CIPHERTEXT • ENCRYPTION & DECRYPTION • KEYS
- 11. CIPHER In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption - a series of well- defined steps that can be followed as a procedure.
- 13. SUBSTITUTION CIPHER A substitution technique is one in which the letters / number / symbols of plaintext are replaced by other letters/numbers/symbols. Ex.: A→D, T→Z, 2→5, 3→6
- 14. TRANSPOSITION CIPHER In the transposition technique the positions of letters / numbers / symbols in plaintext is changed with one another. Ex.: 1 2 3 4 5 6 M E E T M E A F T E R P A R T Y 4 2 1 6 3 5 T E M E E M E F A P T R Y R A T Plain text: MEET ME AFTER PARTY Cipher text: TEMEEMEFAPTRYRAT KEY USED: 421635
- 15. CIPHERTEXT In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it.

- 17. TYPES OF KEYS Public Key Private KeySecret Key SYMMETRIC KEY CRYPTOGRAPHY ASYMMETRIC KEY CRYPTOGRAPHY
- 18. SYMMETRIC VS ASYMMETRIC SYMMETRIC KEY CRYPTOGRAPHY ASYMMETRIC KEY CRYPTOGRAPHY 1) The same algorithm with the same key is used for encryption and decryption. 1) One algorithm is used for encryption and decryption with a pair of keys, one for encryption and one for decryption. 2) The key must be kept secret. 2) One of the two keys must be kept secret. 3) Symmetric encryption takes relatively less time than the asymmetric encryption. 3) Asymmetric encryption takes relatively more time than the symmetric encryption.
- 19. APPLICATIONS OF CRYPTOGRAPHY • Defence services • Secure data manipulation • E – commerce • Business transactions • Internet payment systems • User identification systems • Access control • Data security
- 20. CONCLUSION By the use of cryptography a fair unit of confidentiality, authentication, integrity, access control and availability of data is maintained.
