In 20×8,following events related to Entity A were noted:(1)Entity A sells goods with a warranty under which customers are covered for the cost of repairs of any manufacturing defects that become apparent within the first twelve months after purchase If minor defects were detected in all products sold, repair costs of RMB 6 000 000 would result. Entity A’s past experience and future expectations indicate that ,for the coming year,60 per cent of the goods sold in 20×8 will have minor defects and 10 per cent of the goods sold in 20×8 will have major defects.(2)In November20×8,a customer sued Entity A and made a claim for damages of RMB 2 500 000,as Entity A failed to deliver the goods to the customer in time according to the delivery term of relevant sales contract. When Entity A prepared the financial statements for the year ended 31 December 20×8,its lawyers advised that it was probable that Entity a Would be found liable for making a payment of RMB 2 000 000 to the customer for compensation.（3）Under new environment protection legislation, Entity A is required to fit smoke filters, which costs about RMB20 000 000,to its factories by 30 June 2008.Entity A has not fitted the smoke filters at 31 December 2008.Based on the best estimate of the management of Entity A, it is more likely that Entity A will be imposed a penalty of RMB 10 000 000.（4）Entity A is required by law to overhaul its equipments once three years. The estimated remaining useful life of the equipments is 18 years. Entity A just spent RMB 6 000 000 in overhauling is equipments in 2007.（5）Entity A entered into a sales contract with a customer in November 2008 to sell an equipment at the price of RMB 50 000 000.According to the sales contract, Entity A shall deliver the equipments to the customer in the end of 2009 and the amount of penalty is RMB 600 000 if Entity A or the customer fail to fulfill the contract. Entity A’s original estimated cost of fulfilling the sales contract is about RMB 45 000 000.However,due to the increase of the purchase prices of relevant raw materials, the estimated cost of fulfilling the sales contract increased to RMB 55 000 000 in the end of 2008.No inventory has been prepared by Entity A for the production of the equipment by the end of 2008.Requirement:According to the events described above, determine whether any provision should be recognized in Entity A’s financial statement for the year ended 31 December 2008.If any provision should be recognized, calculate the amount of provision and prepare related journal entries.

Trust is typically interpreted as a subjective belief in the reliability，honesty and security of an entity on which we depend（ ）our welfare.In online environments we depend on a wide spectrun of things,ranging from computer hardware,software and data to people and organizations.A security solution always assumes certain entities function according to specific policies.To trust is precisely to make this sort of assumptions,hence,a trusted entity is the same as an entity that is assumed to function according to policy.A consequence of this is that a trust component of a system must work correctly in order for the security of that system to hold,meaning that when a trusted（ ）fails,then the sytems and applications that depend on it can（ ）be considered secure.An often cited articulation of this principle is:＂a trusted system or component is one that can break your security policy”（which happens when the trust system fails）.The same applies to a trusted party such as a service provider（SP for short）that is,it must operate according to the agreed or assumed policy in order to ensure the expected level of securty and quality of services.A paradoxical conclusion to be drawn from this analysis is that security assurance may decrease when increasing the number of trusted components and parties that a service infrastructure depends on.This is because the security of an infrastructure consisting of many.
Trusted components typically follows the principle of the weakest link,that is,in many situations the the overall security can only be as strong as the least reliable or least secure of all the trusted components.We cannot avoid using trusted security components,but the fewer the better.This is important to understand when designing the identity management architectures,that is,fewer the trusted parties in an identity management model,stronger the security that can be achieved by it.
The transfer of the social constructs of identity and trust into digital and computational concepts helps in designing and implementing large scale online markets and communities,and also plays an important role in the converging mobile and Internet environments.Identity management（denoted Idm hereafter）is about recognizing and verifying the correctness of identitied in online environment.Trust management becomes a component of（ ）whenever different parties rely on each other for identity provision and authentication.IdM and Trust management therefore depend on each other in complex ways because the correctness of the identity itself must be trusted for the quality and reliability of the corresponding entity to be trusted.IdM is also an essential concept when defining authorisation policies in personalised services.
Establishing trust always has a cost,so that having complex trust requirement typically leads to high overhead in establishing the required trust.To reduce costs there will be incentives for stakeholders to“cut corners”regarding trust requirements,which could lead to inadequate security.The challenge is to design IdM systems with relatively simple trust requirements.Cryptographic mechanisms are often a core component of IdM solutions,for example,for entity and data authentication.With cryptography,it is often possible to propagate trust from where it initially exists to where it is needed.The establishment of initial（ ）usually takes place in the physical world,and the subsequent propagation of trust happens online,often in an automated manner.
A.SP
B.IdM
C.Internet
