The sender should not be able to falsely deny later that he sent a message. Service Reliability: The ability to protect the communication session against denial of service attacks. 1 If the message is encrypted, an intruder may have access to the data being sent but does not have access to the “information” being sent. In this case, an intruder may still be able to modify the data, leading to a modification in the information. 2 Security and Cryptography It is extremely important to realize that these are distinct independent requirements and the presence or absence of any one of them does not in any way guarantee the presence or the absence of the other(s).

However, the trapdoor is that if we know one of the prime numbers then the problem becomes the trivial problem of division to obtain the other number. So, one of the primes serves as the key here. Asymmetric key cryptography refers to the process wherein the sender and the receiver use different keys (but the same cipher/algorithm) to encrypt and decrypt messages. 4: Trap Door One-Way Functions 6 Security and Cryptography DK2(EK1(M)) = M. The decryption key is different from the encryption key and should not be derivable from the encryption key.

The set of values from which the key can be selected is known as the keyspace. The larger the keyspace, the more secure is the key since the key would be harder to guess (break). 1 Symmetric Key Cryptography Keys can be used symmetrically or asymmetrically. Symmetric Key Cryptography (SKC) refers to the process wherein the sender and the receiver use the same shared key (and the same cipher) to encrypt and decrypt messages. Such a system is represented mathematically as DK(EK(M)) = M. In our example, suppose A and B decide to use SKC to maintain the confidentiality of their transaction.
