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

http://www.socialresearchmethods.net/kb/sampaper.php Communication Theory of Secrecy Systems? By C. E. 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

SMS encryption using Diife-Hellman May 4‚ 2012 Introduction 1.1 Background Nowadays mobile phone communications (phone calls) are used mostly by everyone due to the GSM technology. In mobile phones there are several services a person can use to communicate other than making a phone call such as; SMS‚ MMS‚ contact registry and cameras. The most commonly used service after phone calls is the SMS that most of us find it easier even faster to share or to communicate with one another. An SMS
