The Journal of Telecommunication Systems & Management is a peer-reviewed, open-access journal. Depending on several other parameters, there different types of Analog and Digital Modulation. The different types of Analog Modulation are: Amplitude modulaiton and Angle modulation. The Digital modulation methods are: frequency-shit keying, phase-shift keying, aplitude-shift keying, on-off keying, continuous phase modulation, orthogonal frequency divison multiplexing, wavelet modulation and quadrature amplitude modulation. These different modulation techniques differ in a varying a single parameter during modulation and keeping the others constant. After transmitting information using the appropriate modulation for a specific application, security of the information is the next priority. Earlier forms of tranport layer security used the Secure Network Programming (SNP) application programming interface (API). Secure Sockets Layer (SSL) was the first cryptographic protocol that contained many flaws in its application. Transport Layer Security (TLS) was developed as an upgraded version of SSL. TLS later became a widely used cryptographic protocol for information security. These protocols, before exchanging information, agree upon a pre-decided cipher/encrypted code, to clear to secure access. Some of the various known TLS/SSL attacks are: renegotiation attack, version rollback attacks, BEAST attack, CRIME and BREACH attacks, Padding attacks, Truncation attacks, RC4 attacks and Heartbleed bug.
