Answer: Requirements phase
Explanation:Requirement phase in the SDL(secure development life-cycle) is the phase where the security is fused with integrity part for any product. This mechanism is done to know about the requirement of the product in the security field. This is done to achieve the completeness in the product and to recover the mistakes that had happened earlier in the product due to security issues.
Other phase given in the option are for making the code, designing the model of product and testing the products aspects respectively.
Input statements allow the user to enter data that a program uses to perform necessary computations. Users enter the data when they <u>encounter the statements like the scanf() or gets() functions in the program.</u>
<u>Explanation:</u>
The scanf() is the function that is used to take inputs from the user with the help of the standard input device,i.e, the keyboard.
scanf() function is capable of taking any data type as an input, though it has to be specified first like %d for integers, %s for strings and %f for floating-point type. The gets() function can only take a string as an input.
Answer:
The concealment cipher.
Explanation:
A concealment cipher also known as null cipher can be defined as an obsolete encryption format that typically involves the mixture of plaintext with non-cipher elements. This ultimately implies that, the plaintext is hidden in another message through encryption.
The concealment cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem.
Basically, the concealment cipher is solely dependent on the clues of the physical factors that mainly affects the sender and receiver in a communication system.
