As I noted in this post, RSA encryption is often carried out reusing exponents. Sometimes, the exponent is exponent 3, which is subject to an attack we’ll describe below [1]. (The most common exponent is 65537.)
Suppose the same message m is sent to three recipients and all three use exponent e= 3. Each recipient has a different modulus Ni, and each will receive a different encrypted message
What is CASB? CASB, or cloud access security broker, is a relatively new term in the cybersecurity space. It is used to define the industry of solutions that protect the data stored in cloud applications, such as Google G Suite and Microsoft Office 365. Though, some argue that CASB is already outdated in favor of Cloud Application Security Platform (CASP).
Gartner defines a CASB as: "on-premises, or cloud-based security policy enforcement points, placed between cloud service consumers and cloud service providers to combine and interject enterprise security policies as the cloud-based resources are accessed."
