  3. decrypted

  4. All of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Data are sending by email for security purpose in encrypted form.

End-to-end email encryption is a method of transmitting data where only the sender and receiver can read email messages. With end-to-end email encryption, the data is encrypted on the sender's system. Only the intended recipient will be able to decrypt and read it.

Email encryption involves encrypting, or disguising, the content of email messages in order to protect potentially sensitive information from being read by anyone other than intended recipients. Email encryption often includes authentication.

________ is a personal security code for GSM subscribers 

  1. SMS

  2. Advice of change

  3. Voice mails

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Voicemails is a personal security code for GSM (global system for mobile communication) subscribers.

GSM (global system for mobile communication) services are a standard collection of applications and features available to mobile phone subscribers all over the world. The GSM standards are defined by the 3GPP collaboration and implemented in hardware and software by equipment manufacturers and mobile phone operators. 

GSM provides recommendations, not requirements. The GSM specifications define the functions and interface requirements in detail but do not address the hardware.

A voicemail system is a computer-based system that allows users and subscribers to exchange personal voice messages; to select and deliver voice information; and to process transactions relating to individuals, organizations, products and services, using an ordinary telephone. The term is also used more broadly to denote any system of conveying a stored telecommunications voice messages, including using an answering machine.

In ___________ cryptography same secret key is used by the sender and the receiver. 

  1. Public key

  2. Private key

  3. Symmetric key

  4. Asymmetric key
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In Symmetric key cryptography same secret key is used by the sender and the receiver.

symmetric-key cryptography. An encryption system in which the sender and receiver of a message share a single, common key that is used to encrypt and decrypt the message. Contrast this with public-key cryptology, which utilizes two keys - a public key to encrypt messages and a private key to decrypt them.

Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext. ... The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information link.

The shared secret is either shared beforehand between the communicating parties, in which case it can also be called a pre-shared key, or it is created at the start of the communication session by using a key-agreement protocol, for instance using public-key cryptography such as Diffie-Hellman or using symmetric-key.

Avalanche effect in encryption is  ____________.

  1. Desirable

  2. Undesirable

  3. Cannot be said

  4. Depends upon the context
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Avalanche effect in encryption is Desirable.

Avalanche effect. ... In cryptography, the avalanche effect is the desirable property of cryptographic algorithms, typically block ciphers and cryptographic hash functions, wherein if an input is changed slightly (for example, flipping a single bit), the output changes significantly (e.g., half the output bits flip).

Avalanche effect, in physics, a sudden increase in the flow of an electrical current through a nonconducting or semiconducting solid when a sufficiently strong electrical force is applied.
