the type of key (asymmetric or symmetric) to use. Please formulate a possible solution‚ and describe the advantages and disadvantages of any solution employed. The best type of key to use in this situation would be public-key cryptography‚ also known as asymmetric cryptography. It is a type of cryptographic algorithm that requires two separate keys. One of those keys is private‚ and kept secret. The other is public and distributed to those who need it. The keys are both needed since they are part

Premium Cryptography Encryption Certificate authority
securely and privately exchange data and money through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority. The private key system is sometimes known as symmetric cryptography and the public key system as asymmetric cryptography. The Hash algorithm (or hash function) is an algorithm that computes a value based on a data object such as a message or file. The object is usually of variable length‚ possibly very large‚ thereby mapping the data object

Computer security and cryptography A computer program system that is supposed to be used only by those authorized must attempt to detect and exclude the unauthorized. Access to it is therefore usually controlled by insisting on an authentication procedure to establish with some degree of confidence the identity of the user‚ thence granting those privileges as may be authorized to that identity. Common examples of access control involving authentication include: * A captcha is a means of asserting

1. Frequency Division Multiplexing Frequency Division Multiplexing is a technique that can be applied when bandwidth of the link is greater than combined bandwidth of signals to be transmitted. Frequency Division Multiplexing technique is the process of translating the frequency of individual channel into per-assigned frequency slots within the bandwidth of the transmission medium. Different carries frequencies are assigned to different users. We can use any modulation scheme to assign carrier

Digital Signature Act 1997 The primary intent of the Digital Signature Act 1997 is to regulate the use of digital signatures and to provide for matters connected therewith. We start with the privacy implications of digital signatures in general. A digital signature is a ’message digest’ encrypted using the sender’s private key. The recipient can recreate the message digest from the message they receive using the sender’s public key. He can then compare the two results to satisfy himself
