  • 1. Cryptkit 1
  • 2. College Name 2
  • 3. HOD Name 3
  • 4. Students Name 4
  • 5. CRYPTKIT using JAVA 5
  • 6. Abstract The purpose of Cryptkit is to implement a real time cryptographic system to enhance security over networks. 6
  • 7. Abstract It uses various cryptographic techniques such as, TDES RSA RABIN PC-1 7
  • 8. Abstract This is an endeavor to implement a real time cryptographic system to enhance security over the networks. There are about various encrypting techniques available for secure transmission of data. But, we use here the standard algorithms namely RSA, RABIN, TDES and PC-1 working on text messages. 8
  • 9. The transmission of data can be made through conventional modems through the telephone lines or via the internet which may be performed using various socket programs. We have used both symmetric and asymmetric encryption algorithms so as to provide a large coverage for the user. The algorithms used were selected by keeping in mind their effectiveness and efficiency. This project was built on JavaTM and can be used in any operating system 9
  • 10. System Configuration Software Requirements: Operating System : Any OS. Language : JAVATM . Java Version : JDK1.2 and higher. 10
  • 11. System Configuration Hardware Requirements: Processor : Pentium II Hard disk : 4GB RAM : 128MB 11
  • 12. TDES(Triple Data Encryption Standards) TDES is a block cipher. It is a symmetric key algorithm. It uses 3x16 rounds for encryption. It is tedious to break the cipher text,since it has 2168 possibilities. It uses the same key for both encryption and decryption. It is mainly used in Defense Security. 12
  • 13. RSA Algorithm RSA is a block cipher. It is an Asymmetric algorithm,since it uses different keys for encryption and decryption. It uses two large prime numbers to generate the public key and private key. It is widely used in network security systems. 13
  • 14. RABIN This is a Block Cipher Algorithm. It is an Asymmetric Algorithm, since it uses different keys for encryption and decryption. The Security lies on the difficulty of finding square roots modulo of a composite number. It is widely used in ATM and Credit Card security systems. 14
  • 15. PC-1 It is a Stream Cipher and works on retroaction function. It is a Symmetric Algorithm. It uses an 128 bit key and operates on 8 bit message blocks. It is mainly used in credit card security, military radio’s and satellites. E.g. to encrypt the launch code of thermonuclear missiles. 15
  • 16. Advantages The algorithms used in this project are the most difficult to break. Since our project is built in JAVA, It can run on any Operating System. It has a good look and feel. It is simple and User Friendly. 16
  • 17. Current Trends The RSA-DES challenge was conducted in order to develop more efficient and stronger cryptographic algorithms. The Finalists of the competition were MARS,AES and TDES. Out of these algorithms AES is widely used in US military communications and TDES is used in all other countries. 17
  • 18. Future Enhancements • We are trying to implement our project in J2ME so that a secure communication can be established even when using mobile phones, that is, while messaging using mobiles. • We are trying to add some more algorithms to our project, that can provide voice and image encryption too. 18
