An Overview of RSA and OAEP Padding
Yutong Zhong · Highlights in Science Engineering and Technology · 2022
Encryption is crucial in information communication. The secret data is transformed into secure form and transferred through various channels. It is important for encryption to prevent unauthorized access to data and the encrypted data can’t be cracked easily. The RSA algorithm was released by Rivest, Shamir and Adleman in 1978. It was the first practical asymmetric cryptosystem and now it is the most widely used asymmetric cryptosystem in the world, covering security of almost everything such as cellphone communication to online banking. In this article, we review the RSA algorithm and the padding schemes used with RSA encryption to avoid semantical insecurity such as optimal asymmetric encryption padding (OSAP).
