BILATERALLY GENERATED ENCRYPTION KEY SYSTEM

摘要

Bilaterally Generated Encryption Key System is a variable password based computationally non intensive symmetric encryption key system dispensing with memorization and exchange of keys, capable of providing one encryption key for each object exchanged between two parties, two different encryption keys per transaction and a plurality of encryption keys for a session, integrating authentication and securing transactions preventing breaking attempts. The Password/Encryption Key is a random permutation of Character Units of Variable Character Set System of authentication devices { Fig. 3}, generated by a Call of random numbers from SERVICE PROVIDER and corresponding Response of USER. Bilaterally Generated Encryption Keys and Non Repeating Bilaterally Generated Encryption Keys are two types of Password/Encryption Keys. Secures every Internet/network transactions of USERs {Fig. 6} including Previously Unknown USERs, by generating many Password/ Encryption Keys of required length using a padding method, from single Password/encryption key input of users and previously unknown users at the instant of transaction.
