RSA Algorithm Definition

RSA Algorithm is a widely used cryptographic algorithm for secure data transmission. Based on the principle of public-key cryptography, it uses two keys: a public key for encryption and a private key for decryption. The RSA algorithm is foundational in securing internet communications, ensuring confidentiality and authenticity. Its strength lies in the computational difficulty of factoring large prime numbers, making it secure against most attacks when implemented properly.

RSA Algorithm Explained Easy

Imagine you want to send a secret message to a friend, but you don’t want anyone else to read it. Your friend gives you a special lock (public key) that only they can unlock with a secret key (private key). You lock your message and send it, knowing only your friend can open it. RSA works like that—keeping messages secure using math instead of physical locks.

RSA Algorithm Origin

Developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman at MIT, the RSA algorithm revolutionized cryptography by introducing public-key encryption, enabling secure communication over open networks.

RSA Algorithm Etymology

The name RSA comes from the initials of its inventors: Rivest, Shamir, and Adleman.

RSA Algorithm Usage Trends

With the growth of digital communication, RSA has been pivotal in securing emails, digital signatures, and financial transactions. However, as quantum computing evolves, concerns about RSA's long-term viability are prompting the development of post-quantum cryptography.
