SSL/TLS communication is bound by SSL certificates. See More: What Is Cybersecurity? Definition, Importance, Threats, and Best Practices How SSL/TLS works A user who sees HTTPS can be assured that all data they enter into the website will be encrypted when sent to the backend server. HTTPS (Hypertext transfer protocol secure) is an extension of HTTP that uses SSL or TLS. TLS 1.3 has changed in the supported ciphers and fixes to the known security vulnerabilities of the previous versions. Currently, version 1.3 is the most secure and efficient so far. They are the starting point of all communication between the client and the application’s servers.Īfter three version releases of SSL, an upgraded protocol named Transport layer security (TLS) was released. Browsers use HTTP to render websites on user devices. It was designed to encrypt traffic that moved using the Hypertext transfer protocol (HTTP). These encryption protocols, like the Scytale, provide a way to encrypt and transfer data between a web client (typical browsers such as Google Chrome) and a web server (where applications like Youtube and Venmo are hosted). PII can be used for blackmail, fraud, or even identity theft.Īt a corporate level, unsecured intercepted data can contain trade secrets, sensitive employee information, or, worse, customer data. This leaves a broad attack surface for Personally Identifiable Information (PII) to be poached by cybercriminals. With many applications and use cases, sensitive data is almost constantly in transit. They use cloud-based SaaS solutions for independent sections of their operations, such as Salesforce for customer relationship management (CRM). įor example, corporations use software for everyday functions, like Slack and Google Workspace, for collaboration. Every sector, be it healthcare or education, runs on applications hooked to the cloud. Governments are increasingly moving their systems online to be more efficient and accessible. The average individual does everything from streaming music to banking on online applications. According to a 2022 report by Statista’s research department, around 180 zettabytes of data will be created by 2025, from the 64.2 zettabyte-volume in 2020. Radicati’s 2021 Email statistics report forecasts that 347 billion emails will be sent every day in 2023. Today, encryption is used in everyday communication, not just in military scenarios. The field of cryptography was also created in the context of the military. Most historical mentions of encryption and encryption protocols involve war or military communications. The cipher is the act of winding and unwinding the strip over the cylinder in a specific direction. The encryption protocol consists of cylinder measurements and the width of the parchment strip. In this case, the mode of encryption is the Scytale. When unraveled, the parchment would not make sense unless the reader rewound it across another cylinder of the same length and circumference. A strip of parchment was wound upon this cylinder, and the message was written across each loop. The Scytale was a cylinder of agreed-upon dimensions. The Spartans of ancient Greece used a tool called a Scytale for encrypting military dispatches. The first recorded use of encryption dates back to 500 B.C. Ciphers are the techniques or algorithms used to do the actual encryption and decryption based on the agreed protocol. Encryption protocols lay out both sides’ structure, tools, and rules. This communication could be between people, servers, organizations, or government agencies. Any mention of SSL/TLS or just SSL usually translates to the latest version of TLS.Įncryption is coding messages so that only the sender and the intended receiver understand them. SSL is the predecessor of TLS, though the terminologies are used interchangeably today. SSL/TLS are encryption protocols that authenticate and protect communication between any two parties on the internet.
