Why security of Rs A depends on problem of factoring large number?
RSA security relies on the computational difficulty of factoring large integers. As computing power increases and more efficient factoring algorithms are discovered, the ability to factor larger and larger numbers also increases. Encryption strength is directly tied to key size.

What is factorization cryptography?
Prime Factorization (or integer factorization) is a commonly used mathematical problem often used to secure public-key encryption systems. A common practice is to use very large semi-primes (that is, the result of the multiplication of two prime numbers) as the number securing the encryption.
Why is factoring important in cryptography?
Prime numbers have the unique property in that they have exactly two factors: 1 and themselves. The reason factoring is so important is mathematicians and computer scientists don’t know how to factor a number without simply trying every possible combination.
What do you call to the process of finding the factors of a given expression?
Factoring (called “Factorising” in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like “splitting” an expression into a multiplication of simpler expressions.
What are the main characteristics of modern cryptography?
There are three major characteristics that separate modern cryptography from the classical approach. It manipulates traditional characters, i.e., letters and digits directly. It operates on binary bit sequences. It is mainly based on ‘security through obscurity’.
What is the art and science of breaking the cipher text?
The art and science of breaking the cipher text is known as cryptanalysis. Cryptanalysis is the sister branch of cryptography and they both co-exist. The cryptographic process results in the cipher text for transmission or storage.
What is the history of cryptography and its evolution?
Only after the 19 th century, cryptography evolved from the ad hoc approaches to encryption to the more sophisticated art and science of information security. In the early 20 th century, the invention of mechanical and electromechanical machines, such as the Enigma rotor machine, provided more advanced and efficient means of coding the information.
What is the difference between steganography and cryptography?
In steganography, an unintended recipient or an intruder is unaware of the fact that observed data contains hidden information. In cryptography, an intruder is normally aware that data is being communicated, because they can see the coded/scrambled message.
