Existing System. Key pre-conveyance framework (KPS) (a.k.a. no interactive gathering appropriation framework) can be viewed as a non-intelligent gathering key exchange. For this situation, the mutual key of a given gathering is settled after the setup. In the event that a gathering is overhauled, then the mass key changes to the common key of the new amass. The disadvantage of KPS is that the client key size is combinatorial huge in the aggregate number of clients (if the framework is genuinely secure). Another downside is that the gathering key of guaranteed gather can't be changed regardless of the possibility that it is spilled surprisingly (e.g., cryptanalysis of figure writings bearing this key). The key size issue might be overcome if a calculationally secure framework is utilized, while the key spillage issue is difficult. Assist, calculationally secure KPS is just familiar for the two party case and the three-party case KPS with a gathering size more noteworthy than 3 is still open. The client key size is combinatorial substantial in the aggregate number of clients (if the framework is unequivocally secure).The assemble key of a given gathering can't be changed regardless of the possibility that it is spilled suddenly.

Existing System. Electrical service for the Building is supplied by National Grid. The existing generator at the Bulding supports life-safety systems within the Building, and may also be used by other tenants of the Project. Subject to system capacity, Tenant shall have the right to install two 60-AMP circuits on the UPS system and back-up generator currently existing at the Building at Tenant’s sole cost and expense. Landlord makes no representation or warranty concerning the said UPS system and/or back-up generator and SPECIFICALLY DISCLAIMS ANY AND ALL REPRESENTATIONS AND WARRANTIES, INCLUDING WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTIBILITY OR FITNESS FOR A PARTICULAR PURPOSE. TENANT’S USE OF, INTENDED USE OF, AND/OR RELIANCE ON SAID UPS SYSTEM AND/OR BACK-UP GENERATOR SHALL BE AT TENANT’S SOLE RISK. The UPS system and back-up generator shall be separately metered and Tenant shall be responsible for a pro-rata share of electrical and maintenance costs and expenses. Landlord shall have no obligation to maintain, repair, service or replace said UPS System and/or back-up generator.
Existing System. The electronic healthcare (e-health) system has been evolved into a patient-oriented service with smaller and smarter wireless devices. As these convenient smart devices have limited computational capacity and memory size, it is harder to protect the user’s massive private data in the e-health system. In the existing system, biometric authentication system is used in order to secure the user’s private data. The Biometric Features is basically used to identify the individuals Face, Fingerprint, Handprint, Voice etc. If we consider the Handprint, it will also be unique for each and every person. In the existing system handprint/fingerprint is used as an authentication factor using various hash functions, bio hash functions and dynamic mechanisms in order to provide security to the user’s private data.
Existing System. Xxxxx and Xxx [9] proposed a property-based proxy re-encryption scheme to enable users to achieve authorization in access control environments. However, Xxxxx and Au [10] pointed out that this scheme does not have Adaptive security and CCA security features. Sun et al. [12] introduced a new proxy broadcast repeat encryption (PBRE) scheme and proved its security against selective cipher text attack (CCA) in a random oracle model under the decision n-BDHE hypothesis. Xx and Xxx [13] proposed a broadcast agent encryption (RIBBPRE) security concept based on revocable identity to solve the key revocation problem. In this RIB-BPRE scheme, the agent can undo a set of delegates specified by the principal from the re-encryption key. They also pointed out that the identity-based broadcast agent re-encryption (RIB-BPRE) schemes do not take advantage of cloud computing, thus causes inconvenience to cloud users. Xxx et al. [14] proposed a secure multi-owner data sharing scheme for dynamic groups in the cloud. Based on group signature and dynamic broadcast encryption technology, any cloud user can share their data anonymously with others. Xxxx et al. [15] proposed a cloud user data integrity check scheme based on polynomial authentication tag and agent tag update technology, which supports multi-user modification to resist collusive attack and other features. Xxx et al. [16] proposed a secure data sharing cloud (SeDaSC) method using a single encryption key to encrypt files. This scheme provides data confidentiality and integrity, forward and backward access control, data sharing and other functions. Xx et al. [17] proposed a new attribute-based data sharing scheme to assist mobile users with limited resources based on cloud computing. Authentication and key agreement is a method that enables both parties to secretly calculate the session key on a public channel, which have been widely studies [18]–[31]. As early as 1993, Xxxxxx [18] proposed that only a difference in the received signals helps achieving perfect cryptographic security, regardless of the enemy’s computing power. But they have not considered the advantage of legitimate communicants. suffices for achieving perfect cryptographic security, regardless of the enemy’s computing power. Xx and Xxx [19] proposed a medical key negotiation scheme based on patient symptom matching. However, He et al. [32] pointed out that Xx’s scheme does not provide an identity tracking and resistance modification function and furthe...
Existing System. The Contractor is responsible to maintain the complete CCTV system and equipment existing at this Facility. The Contractor will have a maintenance Full Service Contract with quarterly service checks (every 3 months) by a qualified licensed contractor to maintain the CCTV system. A copy of the maintenance service checks will be submitted to NYCDOT every quarter. The existing CCTV system includes CCTV cameras with lenses and tamper proof housings with ceiling mounts, Multiplexer(s), DVD recorder(s) and all system cabling and associated conduits. The Contractor shall maintain and secure the existing CCTV system at its own expense. Failure to maintain the system or provide quarterly service reports shall result in the Contractor being subject to the assessment of liquidated damages of $100.00 per day. The Contractor is required to maintain the existing closed circuit TV system (CCTV) at the Facility. The system must be maintained by licensed qualified contractor. If the system fails, it must be repaired or replaced within 8 hours of the system going down. Failure to comply shall result in the Contractor being subject to assessment of liquidated damages of $100.00 per hour over 8 hours specified unless a reasonable explanation is given and approved by NYCDOT’s Parking Operations.
Existing System. The System Design shall be designed so that the high capacity 6 GHz/30 MHz System allows unimpaired, continuous operation of Incumbent's existing low capacity 6 GHz/10 MHz system until Cutover; provided Pathnet shall have the right to temporarily turn down the signal on Incumbent's 6 GHz/10MHz system upon Incumbent's prior written approval as to schedule for such outage.
Existing System. In cloud computing, a resource provisioning mechanism is required to supply cloud consumers a set of computing resources for processing the jobs and storing the data. Cloud providers can offer cloud consumers two resource provisioning plans, namely short-term on-demand and long-term reservation plans. Cloud providers which offer IaaS services with both plans. In general, pricing in on-demand plan is charged by pay-per-use basis (e.g., 1 day). Therefore, purchasing this on-demand plan, the consumers can dynamically provision resources at the moment when the resources are needed to fit the fluctu- ated and unpredictable demands. For reservation plan, pricing is charged by a onetime fee (e.g., 1 year) typical- ly before the computing resource will be utilized by cloud consumer. With the reservation plan, the price to utilize resources is cheaper than that of the on-demand plan. In this way, the consumer can reduce the cost of computing resource provisioning by using the reserva- tion plan
