Public-Private Key. ☐ Hashing. First of all‚ which cryptographic technique can be used to verify the identity of a message’s sender? ☑ Shared Secret Key. ☐ Public-Private Key. ☐ Hashing. OK‚ and how would you use public-private key cryptography to identify the sender of a message? There are two different asymmetrical keys that are used to identify the sender. The way this works is that is it part of a mathematical equation and if it is correct the receiver will know what the message

SHANNON 1 INTRODUCTION AND SUMMARY The problems of cryptography and secrecy systems furnish an interesting application of communication theory1. In this paper a theory of secrecy systems is developed. The approach is on a theoretical level and is intended to complement the treatment found in standard works on cryptography2. There‚ a detailed study is made of the many standard types of codes
