The article is devoted to the implementation of its own approach to the verification of digital certificates using Blockchain direction to protect the Windows operating system. The methods of increasing the level of protection of the Windows operating system that can be used for certificate verification are analyzed and proposed. A new direction of Blockchain is proposed for the implementation of verification, due to the introduction of various verifications, which allows for a qualitative assessment of the authenticity of digital certificates. Today, Blockchain technology is perfect for checking, exchanging and protecting digital certificates. The list of the issuer and the recipient, the signature of the document in an open database, which is the same as in the computers on the open network, is stored. Compared to conventional digital certificates, certificates generated using blockchain technology has the following advantages: no need for intermediaries; certificate verification will be performed by an open source program; you can be sure exactly who and to whom the certificate was issued; the confidentiality of the document being signed is preserved. As you can see, this technology is able to create a powerful, secure, trusted and reliable structure that does not require any intermediaries or regular inspections. Due to the variety of inspection methods, the resources that this area provides, you can achieve maximum validation of both individual certificates and entire chain.Blockchain network is a guarantee of reliability and validity of data, but if someone still wants to confirm the validity of the certificate, you must obtain the public key of the person who signed it. Due to the lack of constant confirmation of certificates, this approach simplifies the administration of the network. The practical value of the study is as follows: the authors have proposed their own approach, which allows you to check single certificates and certificate chains thanks to the Blockchain direction, which allows you to establish a secure connection and reliable data transmission. Because the proposed approach allows multiple certificate checks, it can be further integrated into the Windows operating system and can be used to protect a personal computer or used in corporate structures.

In the modern era, digital communications play a vital role. For an elementary security, encryption is preventing a huge number of problems. When a data is passed through many number of nodes, we don’t know what vulnerability is present at each node. Our data may be affected. GPG encryption is a tool for encrypting emails, digital materials. It uses the concept of key pairs like public key, private key. The public keys are exchanged between the sender and the receiver. The private key is kept as a secret by user. This paper focus on new GNU privacy guard which is a tool to ensure security in huge users traffic and reliable data transmission .

Land Records

The land is a very valuable asset for any government. It’s government job to ensure that the land registration and transfer are done without any fraud, good speed and transparency. The current land registration method employed by the governments are not open to frauds, hacks, and corruption of land records. Fraud is one of the major problems in land registration methods. In this study, the goal is to develop the framework by incorporating the blockchain technique that secures the land data during the land registration and transfer phases by preventing the fraud. The use of blockchain gives us the transparent, decentralized and robust infrastructure to build our framework upon. The blockchain technology is implemented with the asymmetric keys encryption/decryption that securely stores the land registration/transfer data. The data is held using encrypting with the public key of the landowner and storing a hash of the data. The use of the cryptographic function of hashing using SHA. The comparison of using SHA 256 and SHA 512 is given and discussed. The dataset used to compare results is created using 200 records of JSON objects with each object being identical for both SHA256 and SHA512 to remove data bias. The proposed framework with the SHA 512 performed 29% faster than the SHA 256. The results indicate our proposed framework performing better than the works proposed in current research land registration techniques.

Public Keys

In public-key encryption, the secrecy of the public key is not required, but the authenticity of the public key is necessary to guarantee its integrity and to avoid spoofing and playback attacks. A user’s public key can be authenticated (signed) by a certificate authority that verifies that a public key belongs to a specific user. In this chapter, digital certificates, which are used to validate public keys, and certificate authorities are discussed. When public-key is used, it is necessary to have a comprehensive system that provides public key encryption and digital signature services to ensure confidentiality, access control, data integrity, authentication, and non-repudiation. That system, public-key infrastructure or PKI, is also discussed in this chapter.

Data security is important in maintaining the confidentiality of certain data that can only be known by those who have rights. If the data transmission is done by using network, there is a big possibility the data to be known by unauthorized parties.The columnar transposition algorithm is one simple transposition password. Columnar transposition is one of the classic cryptographic algorithms. Columnar transposition is one part of the transposition cipher with cryptographic method where the message is written in a row from a specified length, and then the column per column is read again with a reading sequence based on a keyword. Series length is determined by the length of the keyword. The order of column readings is based on column order.RSA Algorithm is one of asymmetric cryptography, which is a type of cryptography that uses two different keys: public key and private key. Thus, there is one key, namely the public key, which can be sent through a free channel, without any particular security. In this case there are two keys arranged so that they have a relationship in modulo arithmetic equation. In this case, combining both columnar transposition algorithms and RSA algorithms allows security in the form of message data to be very effective for locking the data even better.Keywords: Cryptography, Columnar Transposition, RSA, Java

Vehicular adhoc structures (VANETs) handle the Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs) for their security. In any PKI structure, the check of a got message is performed by checking if the check of the sender is joined into the current CRL, Verifying the reliability of the certification and standard for the sender. In this paper, it has been propose a Vehicular Digital Hash Gen show up (VDHG) for VANETs, which replaces the dull CRL checking process by a profitable revoking checking process. The renouncing check process in VDHG uses a Private Key Infrastructure (PKI), where the key used in finding the VDHG is shared particularly between On-Board Units (OBUs). In like manner, VDHG uses a novel probabilistic key stream, which extras with OBUs to trade and revive an issue key. VDHG can on a very basic level lessen the data torment in light of the message declaration deferral pulled back and the standard assistance structures using CRL.

Communication Scheme

Due to the unique characteristics of blockchain, such as decentralization, anonymity, high credibility, and nontampering, blockchain technologies have become an integral part of public data platforms and public infrastructure. The communication between the stakeholders of a given blockchain can be used as a carrier for covert communication under cover of legal transactions, which has become a promising research direction of blockchain technology. Due to the special mechanism of blockchain, some traditional blockchain covert communication schemes are not mature enough. They suffer from various drawbacks, such as weak concealment of secret information, cumbersome identification and screening of special transactions, poor availability, and low comprehensive performance. Therefore, this paper designs a scheme of covert communication in the Bitcoin blockchain, which takes normal transactions as a mask and leverages the Bitcoin transaction mechanism to embed secret information in the public key hash field. Specifically, we propose a novel key update mechanism combined with the hash algorithm to construct a covert channel. It ensures security and can update the channel to prevent the related problems caused by address reuse. We are taking advantage of the feature of Bitcoin that cannot be double-spent to solve the problem of burning bitcoin when paying bitcoin to a fake public key hash. In our scheme, both parties to the communication are anonymous, and the attacker cannot detect the covert data or track the transaction and address. Our proposed scheme was tested in real Bitcoin blockchain network, and the experimental results were analyzed to verify its security, availability, and efficiency.

And Storage

Public Key Infrastructure (PKI) based or Identity-based Encryption (IBE) based authentication schemes are introduced into network storage systems recently. However, the schemes have unavoidable disadvantages:(1)the exchange of digital certificates are complicated.(2)the public key is long.(3)the transmission of private key is vulnerable. In this paper, we design a network storage authentication scheme using Double-PKG. The theoretical and experimental results show that it can ensure the confidentiality, integrity, availability and non-repudiation during data transmission and storage. Our scheme uses the double authentication infrastructure. And it can effectively protect the key transmission. The data encryption and decryption in experiments are relatively stable, so the overall scheme efficiency has been greatly improved.
